Russian "Dianite" Blue Jade Bangle - 55.5 mm #1
$2 500,00
This particular bangle is a fairly consistent blue with mixes of black and blue shades throughout. There are no cracks/fractures. This bangle is so rare that I have never seen another bangle made from this material. I was lucky to have a large enough piece to make one bangle from the material. The grain direction was extreme on this material making it extremely difficult to have a consistent clean surface and high polish. Because of this difficulty, you can make out some slight unevenness and not perfect high polish but this bangle turned out very nice and will be the conversation piece to have because of it's rarity. A truly one of kind.

Material History
Siberian Blue Jade "Dianite" jade history:
Dianite was named in honor of Diana, Princess of Wales, she was killed in a car crash in Paris since it was discovered in the Eastern Siberian Region of Russia, in 1997, equivalent year. Dianite is just a selection of the Amphibole Group of minerals and contains been called Siberian Blue Jade. It is a form of blue Jade consisting of strontian potassic richterite mixed with whitish quartz-Microcline aggregate that is porcelaneous. It is not cosidered a "true" nephrite jade but is very close and works like a coarse felted nephrite making it difficult to avoid orange peel and undercutting during the final polish.
About My Bangles
I am adding additional information on the grading of each bangle. The purpose is to help educate all buyers and give people the appropriate information to better understand their purchase, and in the case of “high-end bangles,” their investment. This grading information is my personal attempt to inform others of the qualities of the material on a particular item. There are so many false jades, modified jade and simply inferior jade being passed off to uninformed buyers. I usually only work with high quality, untreated materials, but the materials do vary in quality even within the same stone so this will point out and identify everything about each bangle. When artists work on a piece of jade (in this case, a bangle), they get to personally know everything about the bangle. Many online sellers (including ETSY), are selling bangles made by production methods (CNC or many operators doing only one part of the process at a time), which also means a seller will have no personal knowledge of the item.
** Note: Many items stated to be "Jade" on Etsy and Ebay are not. In many cases, price does not indicate this either so buying an expensive item may be a jade replica like glass. There are many other stones including agate, grossular garnet, serpentine (many forms), aventurine... being sold as jade. To make it worse and more complicated, many jadeite stones are being reconditioned and died to be very attractive so they pass general tests to be real. If you see very clear bangles, odds are they are agate, glass or something else. If you see very bright colors of red, yellow, purple... most likely not real. I say this as many buyers are being fooled on-line by these practices.
