Jade was formed by nature, deep in the earth’s crust under high pressure and temperatures, a process that has taken millions of years to complete. Jade refers to two mineral species, Jadeite and Nephrite. Jadeite (silicate of aluminum and crystaline) is found mainly in Burma. The Nephrite (silicate of calcium and magnesium) found in British Columbia, Canada has made it the Jade capital of the world. Typically, B.C. jade is a medium to deep green colour.
