Product Name: Men's Silver orders Fire Opal Ring Size 12/12.5
Got this off eBay a few years ago from a opal jewelry store. Put up a picture of what the seller is has it for. Haven't worn it because it never fit so it's new. 15g Included sellers orders original description below. This is a one of a kind and wraps halfway around the finger and at the same time, is extraordinarily comfortable. This piece measures in at slightly over 1 inch, (knuckle to knuckle). It holds 15 impressive quad-hued opals on the table in blue, red, dark blue, and white. On each shaft is a large triangular shaped opal measuring in at just under 3/4 of an inch wide. One side holds the black opal the other side holds a red opal. Hallmarked at 925, it is solid sterling silver. The ring tapers in the back for comfort down to 10 mm, so you still have full use of your had to write, type, hold a cup, or make a fist. Also, the makers initials are stamped inside. The ring is finished underneath with nothing to scratch or dig into your skin. It is simply a divinely handsome opal ring.
