• Silicon

• Boron

This intricate blend of elements contributes to the gemstone’s unique characteristics and its exceptional beauty. The specific formula, Ca2(Mg,Al)6(Si,Al,B)6O20, reflects the diversity of its chemical makeup and its rarity in nature.

The presence of Si-Al chains, integral to its crystal formation, marks a key feature of serendibite’s structure. These chains define the gem’s triclinic crystal system, contributing to its distinct physical properties and the sharp, vitreous crystals found in nature.

Physical and Optical Properties

As a biaxial (+) mineral, serendibite displays strong birefringence and optical uniqueness with refractive indices ranging from 1.701 to 1.706. These properties make serendibite easily identifiable and highly valued in the gemological community.

The mineral’s optical characteristics, as featured in a mineralogical magazine, are further enhanced by its striking pleochroism, varying from pale yellow to deep blue, with a captivating bluish green hue in between.

Color Variations

Spanning from bluish-grey to almost black, the color spectrum of serendibite is captivating. These variations can also include grayish blue-green to deep blue, green, and brown hues, adding to the gem’s allure. Rarely, serendibite can exhibit pale yellow and greyish blue tones, making these particular stones highly coveted among collectors.
