I JUST GOT THIS RING AND HAVE NO CLUE TO THE STONE. DOES ANYONE KNOW WHAT IT IS? YOUR HELP IS APPRECIATED AND HOPEFULLY MY HEADACHE WILL GO AWAY..
It looks to be either a green turquoise or a green chrysocolla cab.
The setting looks to have rust on it. silver would not, so, I tend to believe a poor quality turquoise or maybe an Eilat stone.
