I have a pendant that I purchased about 15-20 yrs ago at a psychic fair. I was told that this particular stone was rare and the supply would soon be all gone. If I'm remembering correctly, I think they told me it was synthetic or man-made. It is a beautiful teal color with dark areas. The color seems to have crystallized with the color spreading throughout the stone like ice sometimes crystallizes.
I would like to identify this particular stone and can find nothing online that even resembles it. The dealer I purchased from was traveling through and I have no way of contacting them. If I sent you a picture of this stone, could you help me identify it?
