Jade Geology

Jade Geology in Myanmar or Burma

Some geological processes have been unique when the earth was formed. 
Jadeite is a mineral that is restricted to rocks and boulders that have undergone metamorphism at very high pressure but low temperatures. Now, what is this? It is a change of minerals or geologic texture in existing rocks without a melting into liquid magma first.

The change is because of heat, pressure, and fluids which make the inside components and crystal structures change but the rock itself remains solid. It is found in serpentinite only,

Nephrite which is also formed like this had a bit of a different formation and is much more widespread because of this. It is mostly found inside serpentinite. The form is boulders, rocks, and cobbles in river deposits, underground or in mountains.  

The main mining source is at Kachin State Myanmar and in Sagaing division. Since most other sources got depleted by the 16th Century the only source remained here in the north of the country and in Guatemala.

There are certain variants, with traces of chromium and magnesium it becomes imperial green. Usual other colors are lavender, white, red, purple, yellow, brown and other. With traces of manganese, it becomes lavender and purple, without impurities its white. 

A blend with iron brings dark and bright red. If chromium was present at the time the stone was formed under a relatively low temperature of around 300 Celsius.

This is a high-density gemstone

and if feels heavier than usual stones. In your hand, genuine jade must feel smooth cool and somehow a bit like a soap, after holding it the hand it should warm up from the body temperature if this happens there is a good chance it is pure jade.

Burmese jade is getting more popular and prices are rising continuously one spike into the sky was when a necklace was auctioned at November 1997 at Christie's in Hong Kong for more than 70 million Hong Kong dollars.
