Magical power hidden in green light

Her mysterious deep green light has been enticing people since ancient times. She has the longest history amongst jewels, providing us with comfort, creativity and bliss. The minerals formed are beryllia, alumina and silicic acid. The beautiful green is a product of a small amount of chrome within the gemstone.

Colombia is known for the world's highest grade emerald and its largest emerald mine is in Muzo. The Crescent Vert Emerald possesses colors approximately the same as emeralds from the Muzo mine, and shines strongly in blue.
