Known by the poetic phrase “emerald by day, ruby by night,” the alexandrite gemstone represents the pinnacle of gemological wonder, combining extreme rarity with an optical phenomenon that has captivated gem aficionados for nearly two centuries.
This comprehensive guide will take you through everything you need to know about alexandrite stones, from their fascinating discovery in Imperial Russia to the modern challenges of finding authentic natural alexandrite in today’s market. Whether you’re a collector, jewelry enthusiast, or simply curious about this remarkable gem, you’ll discover why alexandrite commands such extraordinary prices and how to navigate the complex world of alexandrite jewelry with confidence.
What is Alexandrite?
Alexandrite is an extremely rare variety of the mineral chrysoberyl, distinguished by its remarkable ability to change colour with different light sources. This strongly pleochroic gem displays a dramatic transformation from bluish green or green in daylight and fluorescent light—often displaying green—to purple red or brownish red under incandescent light. Under incandescent light, alexandrite changes to a purplish-red or raspberry hue. The gem's pleochroism—the ability to show different colours when viewed from different directions—means that alexandrite can exhibit green, orange, and purple-red hues depending on orientation. However, the notable colour change is caused by the gem's unique light-absorbing characteristics rather than pleochroism itself. The finest alexandrites are typically clean and have few inclusions, which enhances their value and appeal, as minimal inclusions allow better light transmission. Alexandrite gemstones with minimal inclusions are highly sought after for their improved light transmission.
The scientific explanation behind this colour change lies in the crystal structure and trace elements within the stone. Chromium ions embedded in the chrysoberyl family matrix selectively absorb specific wavelengths of light. Under daylight, rich in blue and green wavelengths, the stone appears green, while under incandescent light, which contains more red wavelengths, it reveals its ruby-like character.
Alexandrite belongs to the chrysoberyl family, sharing the chemical formula BeAl₂O₄, but its unique optical properties set it apart from other stones in this group. The International Gem Society recognizes alexandrite as one of the most sought-after gemstones, with fine quality alexandrite commanding prices that rival or exceed those of diamonds, emeralds, and rubies.
What makes alexandrite truly exceptional is not just its colour change, but the intensity and purity of that transformation. The most valuable specimens show a complete shift from a vivid green to an intense red, with no muddy or brownish intermediate tones. This perfect colour change is exceptionally rare, making authentic alexandrite practically unaffordable for most collectors when found in larger sizes.
The Fascinating History of Alexandrite Discovery
The story of alexandrite begins in 1830 in Russia’s Ural Mountains, where Finnish mineralogist Nils Gustaf Nordenskiöld first identified this remarkable gemstone. The discovery occurred in emerald mines near the Tokovaya River, where workers initially mistook the green crystals for emerald. However, when examined under candlelight that evening, the stones revealed their true nature by displaying brilliant red flashes. Historically, the Ural Mountains were the primary source of natural alexandrite.
The gem was named after Alexander II, who would later become Czar of Russia. This naming proved prophetic, as the stone’s red and green colours perfectly matched the military colours of Imperial Russia, making it an instant symbol of Russian heritage. The timing of the discovery, coinciding with Alexander II’s coming of age, seemed almost mystical to Russian nobility, who embraced the gem as a symbol of good fortune and imperial power.
George Kunz, the legendary gemologist working for Tiffany & Co., played a crucial role in introducing alexandrite to international markets. His expertise and marketing helped establish alexandrite’s reputation as one of the world’s most desirable gemstones. Kunz recognized that the gem’s rarity and unique properties would appeal to wealthy collectors seeking something truly extraordinary.
By the early 1900s, the original Russian mines in the Ural Mountains had become largely depleted, making Russian stones incredibly valuable antiques. Today, alexandrite is sourced from Brazil, Sri Lanka, Tanzania, and East Africa, with varying quality. Original Russian alexandrites are considered the gold standard for quality and command premium prices at auction houses worldwide. The depletion of these historic mines marked the end of alexandrite’s first chapter and the beginning of a global search for new sources.
Alexandrite’s Unique Colour-Changing Properties
The colour-changing phenomenon in alexandrite is a result of complex interactions between the gem’s atomic structure and different light sources. Unlike simple pleochroism seen in other gemstones, alexandrite exhibits what gemologists call the “alexandrite effect”—a dramatic and complete transformation between two distinct colour appearances.
The science behind this effect centers on chromium absorption at approximately 580 nanometers wavelength. This critical absorption point lies perfectly between the blue-green and red portions of the visible light spectrum. Under daylight or fluorescent light, which is rich in blue and green wavelengths, the stone appears green to bluish green. When illuminated by incandescent light, which contains more red wavelengths, the gem transforms, displaying purple-red to brownish-red hues.
True alexandrite must demonstrate this dramatic colour change to be considered genuine. Many stones in the chrysoberyl family exhibit colour variation, but only those that display the characteristic green-to-red transformation qualify as authentic alexandrite. This distinction is crucial for collectors, as colour change intensity directly correlates with value.
Quality grading for alexandrite colour change follows a specific scale. The finest specimens show a complete transformation from pure green to pure red with high colour saturation in both appearances. Secondary colours or muddy tones significantly reduce value. Most alexandrites show some degree of secondary colouration—Sri Lankan alexandrite often displays yellow undertones, while stones from East Africa may show brown modifiers. The cut of the stone also plays a vital role in enhancing the gem's colour and can reveal or intensify its colour-changing properties, making the overall appearance more vivid and valuable.
The strength of the colour change also varies significantly between specimens. Fine colour material demonstrates an immediate and dramatic shift that’s visible even in mixed lighting conditions. Lower quality stones may show only subtle colour variations, while even lower quality stones might display muddy or indistinct colour changes that barely qualify as alexandrite effect.
Types of Alexandrite
Alexandrite, celebrated for its dramatic colour change and exceptional rarity, comes in several distinct types that reflect its origin, colour profile, and overall quality. Natural alexandrite is the most coveted, with stones from different regions displaying unique optical properties and hues. Russian alexandrite, the original and most sought-after, is renowned for its striking blue-green colour in daylight and a vivid purplish-red under incandescent light. These stones are extremely rare and command premium prices, especially when they exhibit a strong, clean colour change with minimal secondary tones.
Sri Lankan alexandrite, while rare, often displays a slightly different palette—typically green in daylight, transitioning to brownish red or orangey red under incandescent light. These stones are available in larger sizes and are prized for their clarity, though their colour change may be less intense than that of their Russian counterparts. Sri Lankan alexandrite often appears deep olive-green in sunlight and can show good colour intensity, adding to its appeal.
Brazilian alexandrite is another important type, known for its pale blue-green to pale mauve colour shift. While Brazilian stones may not always achieve the same colour saturation as Russian or Sri Lankan alexandrite, they are still highly valued for their beauty and rarity, especially when they display a clear, distinct colour change. Brazilian alexandrites are among the most sought-after and have experienced major price increases due to their desirability.
In addition to natural varieties, synthetic alexandrite—also known as lab-created alexandrite—offers a more accessible alternative. These stones are engineered to mimic the colour change and optical properties of natural alexandrite, making them a popular choice for those who appreciate the gem’s allure but seek a more affordable option. While synthetic alexandrite can be visually stunning, natural stones remain the gold standard for collectors and connoisseurs due to their geological origin and extreme rarity.
Cat’s Eye Alexandrite
Among the rarest and most mesmerizing forms of alexandrite is cat’s eye alexandrite, a gemstone that displays a luminous, moving band of light across its surface—a phenomenon known as chatoyancy. This effect is caused by the presence of fine, needle like inclusions within the stone, which reflect light in a way that creates the appearance of a cat’s eye. As the stone rotates, the eye seems to glide across its surface, adding a dynamic, mysterious quality to the gem.
Cat’s eye alexandrite is extremely rare, with only a small fraction of alexandrite stones exhibiting this unique optical effect. The sharpness and intensity of the cat’s eye, combined with the stone’s ability to change colour in different directions and lighting conditions, make these gems especially prized among collectors. Sri Lankan alexandrite is particularly renowned for producing high-quality cat’s eye stones, with some specimens displaying a crisp, well-defined eye that appears to follow the viewer’s gaze.
The value of cat’s-eye alexandrite is determined not only by the stone's clarity and colour change, but also by the strength and definition of its chatoyancy. Stones that combine a vivid colour shift with a sharp, centred cat’s eye are considered true treasures in the world of fine jewelry. For those seeking a gemstone that embodies both the magic of colour change and the intrigue of optical phenomena, cat’s eye alexandrite stands in a class of its own.
Global Sources and Mining Locations
Following the depletion of Russia’s Ural Mountains deposits, the jewelry industry has identified several new sources of alexandrite worldwide, each producing stones with distinctive characteristics. Brazil’s Minas Gerais region emerged as a significant source in the 1980s, producing alexandrite with exceptional colour saturation despite typically smaller carat weight. Brazilian stones often show intense colour change with good clarity, though most specimens remain under one carat.
Sri Lanka has long been known for producing alexandrite with excellent transparency and good colour change, though Sri Lankan alexandrite typically displays lighter colours than Russian or Brazilian material. These stones often show yellow or brown secondary colours, but can achieve impressive sizes with good clarity. The alexandrite colour in Sri Lankan material tends toward yellowish-green in daylight, transforming to orangish-red under incandescent light.
African sources, particularly Tanzania and Madagascar, have produced some remarkable alexandrite specimens in recent decades. East Africa has yielded stones with intense colours and good size potential, though many show brown overtones that affect their desirability. Tanzanian alexandrite often displays strong colour change intensity but may lack the pure hues of the finest Russian material.
Madagascar has emerged as another important source, producing alexandrite of varying quality. Some Malagasy stones rival the finest material from traditional sources, while others show weaker colour change or significant secondary colours. The quality diversity from Madagascar means careful evaluation is essential when considering these stones.
Each source location imparts characteristic features that help gemologists identify the origin. Russian stones remain the benchmark for quality, featuring pure colour change and exceptional colour intensity. However, fine quality alexandrite from any source commands significant premiums due to the gem’s overall rarity in the marketplace.

Evaluating Alexandrite Quality: The 4Cs
Colour
The most important factor is the strength and purity of the colour change—from pure green in daylight to pure red under incandescent light. High colour saturation and a complete transformation are rare and highly valued. Stones with muddy or secondary colours like yellow or brown are less desirable.
Clarity
Natural alexandrite often contains inclusions, including needle-like ones that can produce the rare cat’s eye effect—a phenomenon known as 'cat's eye' that is highly prized in chrysoberyl gemstones for its striking optical appearance and significance in grading. While eye-clean stones are preferred, some inclusions are acceptable due to the gem’s rarity. In rare cases, unique inclusion patterns in alexandrite create 'cat's eye alexandrite', which displays a distinct chatoyancy effect and is especially valued by collectors. The cat's-eye effect occurs when alexandrite is cut as a cabochon, resulting in a sharp, luminous band of light across the surface that enhances the gemstone's attractiveness and value and aids in its identification. Inclusions also help distinguish natural from synthetic stones.
Cut
Cutting alexandrite requires skill to maximize the colour change and brilliance, balancing weight retention with optical performance. The quality of the cut can significantly enhance or reveal the gem's colour and its remarkable colour-changing properties, increasing both its visual appeal and value. Popular cuts include oval, cushion, and round brilliant, chosen to best showcase the gem’s unique properties.
Carat Weight
Size greatly affects price; stones over one carat are rare, and those above three carats are exceptionally scarce and much more valuable. Most alexandrites that are available weigh under one carat, and those over five carats are very rare. Prices increase exponentially with size, making larger stones highly sought after by collectors and investors. Zimbabwean alexandrites are typically small, weighing under one carat, and produce a fine colour change.
Natural vs Lab-Created Alexandrite
The development of synthetic alexandrite technology since the 1960s has created a parallel market of lab-created alexandrite that replicates the colour-changing properties of natural stones. Several methods produce synthetic alexandrite, including flux growth and floating-zone techniques, creating stones chemically and physically identical to natural alexandrite.
Distinguishing natural from synthetic alexandrite requires advanced gemological equipment and expertise. Both natural and lab-grown stones share identical chemical composition (BeAl₂O₄ with chromium), crystal structure, and optical properties, including the characteristic colour change effect. Visual inspection alone cannot reliably separate natural from synthetic material.
Professional identification relies on internal features visible under magnification. Natural alexandrite typically shows curved growth lines, characteristic inclusion patterns, and specific fluorescence behaviors under ultraviolet light. Synthetic stones often display straight growth lines, different inclusion types, and subtle variations in spectroscopic signatures.
The price differential between natural and synthetic alexandrite is enormous. While lab-grown alexandrite offers colour-changing experiences at accessible prices, natural stones can cost thousands of dollars per carat due to their geological rarity. This price gap makes professional certification essential for high-value purchases.
Market acceptance varies significantly between natural and synthetic alexandrite. Collectors and investors focus almost exclusively on natural stones, viewing them as rare geological treasures. Fashion jewelry markets readily accept synthetic alexandrite for its beauty and affordability, creating distinct market segments.
Simulated alexandrite represents another category entirely, typically using other colour-changing materials or treatments to approximate alexandrite’s appearance. These simulants lack the chemical and optical properties of true alexandrite and should not be confused with either natural or synthetic versions.
Alexandrite Pricing and Value Factors
Natural alexandrite prices vary widely by quality, with the finest stones commanding over $50,000 per carat, making them among the most expensive coloured gemstones. This high value stems from alexandrite’s extreme geological rarity and strong collector demand. Unlike other precious gems with multiple sources, high-quality alexandrite remains scarce worldwide, driving prices to exponential heights for stones with exceptional colour change and clarity. Size also dramatically impacts price, with larger stones commanding premiums far exceeding those of most other gems. Russian antique alexandrites fetch additional premiums due to their historical significance and legendary status.
The investment appeal of alexandrite is fueled by its rarity, distinctive colour-changing property, and limited supply, making it a sought-after alternative to traditional precious stones. While synthetic and simulated alexandrite exist, natural stones with perfect colour transformation and high clarity remain the most valuable and desirable. Collectors and investors should focus on acquiring top-quality specimens, as these offer the greatest potential for long-term appreciation compared to other gemstones.
Gemological Properties and Characteristics
Alexandrite’s technical properties reflect its position within the chrysoberyl family while highlighting the unique characteristics that create its famous colour change. The orthorhombic crystal structure provides the foundation for the gem’s optical properties, including its pleochroism and birefringence. The gem's pleochroism is particularly strong—alexandrite is a trichroic gemstone that displays green, orange, and purple-red hues depending on its orientation. However, it is important to note that the notable colour change of alexandrite is caused by its unique light-absorbing characteristics rather than pleochroism itself.
With a hardness rating of 8.5 on the Mohs scale, alexandrite ranks among the most durable gemstones suitable for fine jewelry. This hardness places it above quartz (7) and topaz (8) but below corundum (9) and diamond (10), making it highly resistant to scratching and suitable for everyday wear in protective settings. Alexandrite has a Mohs hardness rating of 8.5, making it a durable gemstone suitable for any jewelry setting.
The specific gravity of alexandrite ranges from 3.70 to 3.78, reflecting its dense crystal structure. This relatively high density helps distinguish alexandrite from lighter simulants and provides another diagnostic tool for gemological identification.
Refractive index measurements range from 1.746 to 1.755, resulting in moderate brilliance and light return when properly cut. The birefringence (0.008-0.010) contributes to the gem’s optical character while remaining low enough to avoid problematic doubling effects in most cutting styles.
The chemical composition BeAl₂O₄ with trace amounts of chromium defines alexandrite’s fundamental character. The chromium content, typically less than 1%, creates both the colour and the colour-changing properties that make alexandrite unique among gemstones.
Fluorescence properties vary in alexandrite, with some specimens showing red fluorescence under long-wave ultraviolet light. This characteristic can aid in identification but varies significantly between sources and individual stones.
Treatments and Enhancements
Natural alexandrite rarely receives treatment due to its extreme value and the risk of damaging such precious material. The rarity and high cost of rough alexandrite make most enhancement procedures economically unfeasible, as any damage could result in catastrophic value loss.
Heating is occasionally used in alexandrite treatment to improve clarity or colour intensity. However, such treatments carry significant risks and may not achieve desired results. The complex chemistry responsible for alexandrite’s colour change makes it unpredictable under heat treatment.
When treatments do occur, full disclosure becomes essential for maintaining market integrity. Professional certification from recognized gemological laboratories provides documentation of any treatments, allowing buyers to make informed decisions about treated versus untreated stones.
Detecting treatments in alexandrite requires sophisticated gemological equipment and expertise. Changes in inclusion characteristics, internal stress patterns, or spectroscopic signatures may indicate treatment, though these signs can be subtle and require professional evaluation.
Market acceptance of treated alexandrite differs significantly from that of untreated material. Collectors and investors typically prefer untreated stones, viewing them as more authentic and valuable. The premium for untreated alexandrite reflects this preference and the rarity of finding natural stones that require no enhancement.
Verification of untreated status requires certification from reputable gemological laboratories with experience in the examination of alexandrite. These institutions possess the equipment and expertise necessary to detect subtle signs of treatment that might escape less sophisticated analysis.
