The listing, Copper and Rhinestone Ring, Sz 7-1/2 has ended.
I have never seen a ring like this with a copper band before, but here it is. Size is about 7-1/2. The 'stone' is over 1/4" on each side! It is very cleverly cut so that it sparkles no matter which way you look a it. It may be a cz, I don't know. If you look where the band gets near the stone, you will see a bit of silver on the copper band. The maker plated the sides of the ring with silver or chrome and a bit of it spread to the copper band. This is a very eye-catching ring!
