Stone Question… I have a ring, probably originally purchased by the
owner in the 30’s or 40’s. The stone is 3/4 inch x 1/2 inch, black
stone, with what looks like turquoise in two spots. The black part
is marked up, not smooth at all, the blue green part is smooth and
seems to be surrounded by the black.
What is this? Is it turquoise? If so what kind? what is the black
stone part? I’ve looked at pictures, seems more like Tibetan
Turquoise but the amount of black inthe ring and the amount of
Turquoise as far as surface area seems to be equal. I’ve never seen
a ring like this before.
Cautious to work on this piece, Ilene
