Boulder Opal Ring
This ring features a natural, untreated piece of Boulder opal from Australia. This was one of my finds from Tucson. I picked this piece up as well as some others from a dealer directly from Australia. Its opalescence carries colors of purple and shades of blue with bits of green flashes. This precious stone measures 13mm x 36mm and sits in a sterling silver, prong setting. This ring is a size 9.
