When I saw this thin sliver of intense blue/green boulder opal I had to have it! Thought I'd pair it with a set of meandering gemstones. Top to bottom--iolite, swiss blue topaz, green tourmaline, blue tourmaline and london blue topaz sparkling round cuts add just the color reference to the opal. I set them on one of my wave band rings with 18k gold wires running through. This ring fits a size 8.
