This is a three carat brazilian amethyst. I had planned on having it set. My girls are still to young for this kind of jewlery, I am more of a dainty jewlery girl ( I was going through a faze I guess!!) And it's taking up space in my jewlerybox. I will throw in these black, white and lime green cabochon cut gems, I don't remember what they are, but they would be perfect for a brooch... for free.
