From the customer I learned that the green opal is the matrix that surrounds raw opals. She pointed out the green flecks of shiny opal running through the stone. So nice to know that the necklace went to someone who knew what it was and who really appreciates the stone.I have several more of these beauties to turn into new treasures.
I was also invited to go to a meeting of a local gem and mineral club. I could really use more education on the stones I work with. I just might have to check out this group.
