JADE STONE
This is a natural untreated parcel of jade [Nephrite] from Siberia .ideal for rings or pendants.I purchase this material from Russian sellers at the Tucson gem show.

Size 11 x 7 x 5 mm app
This material can only be mined for 2 months of the year due to the cold weather.
Nephrite is a rock comprising mostly massive microcrystalline to cryptocrystalline felted amphiboles of the tremolite - actinolite series.
Nephrite is one of the two rocks termed as jade, the other being jadeitite = jadeite jade, consisting mostly of jadeite. Both are extremely tough and resistant to fracture such that they have been used for making choppers and blades since Neolithic times.
Jadeite and nephrite are both regarded in China as 'zhen yu', 'genuine jade'. It was not until the beginning of the 19th century that mineralogists and gemmologists started to differentiate between them, since they bear a considerable resemblance to each other in terms of their appearance, their hardness and the properties they exhibit when being processed. Both are tough, since they consist of dense, close-grained, matted aggregates, but they differ from one another in their chemical composition and colours. Nephrite ranges mainly from mid to dark green or grey-green, but it can also be white, yellowish or reddish. Rarer, and somewhat tougher, jadeite displays hues which include green, but also white or pink, and reds, blacks, browns and violets. In both minerals, the way the colour is distributed varies a great deal. Only in the very finest jade is the colour evenly distributed. Both nephrite and jadeite often have veins, blemishes and streaks running through them, though these may not always be regarded as flaws. On the contrary, some of these patterns are considered particularly valuable.

Why are users outbidding themselves?
When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.
When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users maximum limit.
