This one-of-a-kind stunner reminds me of a disco ball! This 18k white gold ring consists of a genuine round, faceted Blue Topaz, made by an Italian designer and directly imported from Italy by our jeweler. The top of this ring measures 20 mm, tapering to 2.5 mm at the base of the shank. This ring has an entire weight of 8.5 grams. This ring is a finger size 7, but it can be reasonably altered at no charge. If you require a specific size please make note in the comments section at checkout.
