This is an unusually swirled piece of nephrite, with some slight chatoyance. It almost resembles seraphinite, but it's definitely jade. DSC_0378_Nephrite jade cabochon by Stephan Telm, on Flickr Nephrite jade has a chemical composition of Ca2(Mg,Fe)5Si8O22(OH)2. When the proportion of iron to magnesium is higher, the jade is darker green. With the amounts of iron and magnesium being variable, all iron yields "black" jade; all magnesium yields white ("mutton fat") jade. In this piece, one can see nearly both extremes and some in-between compositions.

Very cool cab. Pattern is awesome! Somewhere, I have a big block of similar material from the jade beds at Darrington, Washington if I've not slabbed it up yet....Mel
