I found this at a good price and bought it because it was different than anything else that I had. The colors you see are pretty true; they range from a slightly minty-ish green on the right to more brownish-yellow on the left, for a somewhat muddy color. Its unusual color was interesting contrasted with this very black matrix that has, when viewed under a jeweler’s loupe, some very dark brown spots of matrix that is almost as dark as the black.
@Jason Thanks for the insight! Yes…large stone, I’d say around 2.5 inches long.
Now that you’ve jogged my memory on that it could be Chinese, I’m vaguely recalling a post here, I think, where the name “dragon skin turquoise” comes to mind. I’ll have to look for that one.
