15dm068 ((TOURMALINE)), $5 MINIMUM BID, 1.5 .5 x .5 cm, Minas Gerais, Brazil, Thumbnail | |
Here is a very dark blackish green lustrous terminated Tourmaline. It is hard to tell but I do not think it is opaque black. Edge seems to show a bit of color when back lit. ex Dennis McMurdie collection, a local Utah teacher and mineral collector. |
