About
Emerald
Emerald is the green variety of the mineral beryl, colored primarily by chromium and sometimes vanadium. Unlike ruby and sapphire, emeralds typically contain natural inclusions known as jardin, which are accepted as part of the stone’s character. High-quality emeralds are rarer than diamonds, and fine specimens command premium prices. Historically favored by royalty and scholars, emerald symbolizes renewal, harmony, and intellect.
