Virgin Valley Black Opal - dry

This is a 85 caret Virgin Valley Black Opal dug in 1987 at the Rainbow Ridge mine in the Virgin Valley. I dried it out over a year's time with a method suggested to my by a friend. It has been dry every since, never in the water.
I Opticoned it a year ago, intending to finish the polishing job I started way back in 1988, but at age 88 I discovered that I no longer have hand and finger control for the job!
This piece could be sawed into several cab-sized pieces if desired. And were it fully polished it would show the colors far better. I have sold all but two opals I dug in the Valley over the years and this is one of them.
