Opal is the birthstone for October.
This ring features a 3mm Opal cabochon set on to a 1.5mm wide handmade polished sterling silver beaded band ring. Beaded is a simple patterned texture of solid silver wire. Since this ring is handmade, sometimes there might be small hammer or file marks.
In all the photographs, I am trying to show the fire that the stone has in it. If rainbow was a selection for stone colour that's what I would have chosen. There is blues, reds, pinks, and greens in this stone.
