This is a koroite opal that I love from my collection. The green faceted stones are tourmalines that I was saving for several years to do a individual design for. I thought they were too special to include with another stone. But they were such a perfect match for the green in the opal, (A match that would otherwise be close to impossible.) that I used them in this design. And given how beautifully the stones work together, I'm really glad I did. It's sterling and the actual size is 2.5"
