Product Name: Boulder Opal & Iolite Pendant in Sterling Silver, shop One of a Kind
Absolutely Fabulous shop Boulder Opal and Iolite Pendant set in Sterling Silver. This Pendant appears to be a one of a kind Artisan piece as I could not find a piece like this. The Boulder Opal is in a trapezoid type shape and is bezel set. The opal has gorgeous deep blue and green colors. There is a deep purple/blue stone that I believe is an iolite, prong set next to the swirl shaped bail. This piece is about 2 1/4 inch long and about 1/2 inch at its widest. The bail is wide and can accommodate a large chain. The back is stamped, Sterling with makers mark Noble. I was unable to identify the designer and therefore felt it was a one of a kind piece by an artisan. This Pendant is in excellent pre-owned condition. Estimated Retail Value is $300.
