Characteristics of the Traditional Cardinal Gems
Cardinal gems are distinguished by their exceptional hardness, brilliance, and rarity, making them some of the most coveted treasures on Earth. Each gemstone possesses unique physical properties that contribute to its allure and value. The gemstone properties, such as hardness, color, and mineral composition, significantly enhance the allure of cardinal gems.
Diamonds, the hardest naturally occurring substance on Earth, score a perfect 10 on the Mohs scale of hardness. This incredible durability and dazzling brilliance make diamonds a symbol of enduring love and a favorite for engagement rings.
Emeralds, a form of the mineral beryl, are renowned for their vibrant green color, which comes from trace amounts of chromium and vanadium. Their high level of transparency and rich hue make them highly prized in the world of gemstones.

Most of the diamonds we see today hail from the rich mines of Africa, a continent that has become synonymous with diamond production.

Diamonds are formed deep within the Earth’s mantle and are brought to the surface through geological processes such as volcanic eruptions. These gems are not only a girl’s best friend but also a testament to the resilience and beauty found in nature.
