I have a large emerald cut synthetic amethyst that was just taken out of a ring. It is 12mm by 5mm. It weighs 4.41 grams (just over 22 carats). I have a couple of pictures of what it looked like in the ring before it was removed but this is just the stone without a band. The last picture is the back of the stone, which is also in good condition. At $3 per carat it would be $66.15. I’m asking just $40. See my other ads for jewelry, artwork, home decor and more.
