The stone that most people call jade and is common in Chinese and oriental carving like figurines and ancient buttons and burial items is nephrite, the indigenous stone found in New Zealand, China, California, Siberia and all over the world in different color and purities. Nephrite is about the hardest stone there is and it is practically only diamonds and other pieces of nephrite that can cut it. The majority of carvings however that you see in antique stores is actually serpentine or what is lovingly called soapstone. It does have a soapy look to it buy it does not make bubbles. Nephrite also has a "wet" look to its hardness is partly due to is fiberous nature.
The gemstone often called jade is not nephrite but is actually Jadeite, a mineral related to nephrite but is unique to itself. Superb jadeite can be so translucent it can approach transparancey, and if the sample is thin and clear enough you can read a type through it. Most jadeite is at least somewhat translucent and the more transparent it is, coupled with intense colors especially a rich green makes it probably the most valuable per carat weight gemstone. Although not as rare as some other gem stones, carat to carat jadeite is much more valuable than any fancy blue diamond or ruby and it held the worlds record for gems per carat for part of the 20th century. No super 300+ carat samples are known to exist like in diamonds, and the value is dictated by the auction houses of China where bidding really has no limits these days and without doubt the finest examples may trade hands behind closed doors. The most important source of jadeite is in Burma, and there are no legal exports out of Burma, now called Mynamar at this time. The histroical deposits of Burma jadeite date no farther back than about 1840 and before that jadeite was only a legend in the east at best and unknown in the west. The mines are not well documented but there is every reason to believe that all occur in an area of 20-30 square miles. alx p.s. needless to say jadeite is one of my keen interests. a

Thanked: 23eleblu i just bought one of those stones from the jewelery website listed and i thought for the cost and $20 postage was worth trying even if it just ends up in my unused stone colection,how does the stone you got perform and of course compares to black akansas's and those new thurigans from timbertools,
alx do you know those stones on the jewelery site are made of is it nephrite or something else,are there any sites that sell genuine jade stones as i've always been intrigued by them but have not seen many for sale,

Hi Alucard
No, sorry I do not know of a specific seller of nephrite, but if you do find a seller who is selling nephrite or is claiming to sell blocks of nephrite I would demand a money back guarantee. Antique stores are full of pseudo nephrite carvings that are actually serpentine. One way to determne true nephrite is to try and scratch it with a super hard knife blade. True nephrite will not scratch, it is harder than steel. In fact for that matter if you find a piece of so called nephrite, look for test scratches. alxLast edited by alx; 07-18-2011 at 01:29 PM.
