Has anyone ever seen one of these, I can't locate anything like it, I was initially told it might be chromium in matrix, I actually live in one of the richest mineral and gemstone heavy area's of the US, so I don't have to buy. But have lots to sell, is there an easier way to identify stuff, like sapphires, rubies, and others. It's like jasper and agates tons of different types. Even my jade. Type? Anyhow what is this ? The second picture is either jadeite or Nephrite?
