The listing, Sterling Silver Ring with Diamond and Black Stone Center - Free shipping! has ended.
This ring is of unknown size, but I have tiny fingers and it is too big on all of them, so at least a 7. The center gem is unknown but black with sparkles, similar looking to tiger's eye and it is accentuated with two diamond ingots (I do not know if they are real diamonds or not), but the ring is verified 925 silver as indicated in the photo.
