This is a beautiful sterling silver and 24 K gold ring. Featuring one boulder opal, this ring was made by Bimonia, based in Paris, France. Photos used by Bimonia's permission. Handmade and signed. Size 5.5 to perhaps 5.75, see photo. Silver is matte finished with 24K gold sheeting pieces soldered on the silver...really shows up in the sun! Opal has typical rough spots, inclusions and odd spots. It is offset so layering is possible with this ring. I had it resized to be 5.5- 5.75 (not 6.5 in description in photo.) Very good condition and comfortable to wear.
