Turquoise with white?

Any idea what type of turquoise this might be? The white portions are that white and the dark matrix is black.

Usually when you see white like this it didn’t take during the stabilizing period. I think it would be difficult to id. That coral looks like it is glued on the silver?

Good to know. I think the “red” (whatever they are) are glued on too. Haven’t gotten far enough to test for plastic yet. The stone is huge and there is a lot of silver so was thinking it could be born again as something else (or not).
