GENUINE JADE includes ONLY the minerals JADEIT, NEPHRIT and MAW SIT SIT .
Today, countless green minerals and rocks are offered as JADE, especially in the jewelry sector. "CHINA JADE" in particular is usually only SERPENTINE (much softer and available in large quantities), and there are also JADE imitations and imitations.
The JADE mineral NEPHRIT, like the mineral JADEIT, is very hard, dense-felt and tough. NEPHRITE is predominantly olive green to black in color. JADEITE, on the other hand, can occur in all possible colors. The most famous JADEITE variety is the IMPERIAL or KAISER JADE from NORTH BURMA - an emerald green, transparent JADEITE - good stones are incredibly expensive. 1 kg currently costs several million dollars!
This rough stone NEPHRITE is cut on one side, but NOT polished. The mineral is so hard and densely felted that we need a special coolant to cut it on the diamond saws - which is why the cut surface already appears polished.
The piece comes from the CASSIER MINE in BRITISH COLUMBIA - CANADA
