crystal opal

A rainbow crystal opal!

This was a piece of rough crystal opal that had come in a batch from Australia.  It had a slight dull flicker of rainbow colours and was on a sandstone backing. The original stone was cracked into three and I tried hard to work with the pieces but they were really quite small and fiddly.  I thought I’d have a play and mount one   onto black agate,  primarily so I could cut and polish the opal more easily.

I used a two part crystal clear epoxy and made some lamp black to darken it down. After waiting, I  dopped the stone and then trimmed the back down .  Everything felt much easier to control.

It was a real joy to work on! Every part of my cutting and polishing revealed more colour, vibrancy and brilliance. There is a small inclusion of sand on one edge but to remove that would have meant effectively destroying the stone… you can hardly see it without a loupe. When I reached the 3000 grit, the rainbow colours were really showing through.

The final polish gave me a big smile. It may only be a small stone and effectively it’s a rather thick doublet but I love it.

I’ve taken the photographs in a near daylight with an artificial source. Please feel free to comment on the post and photographs .

      That rather depends on what size rough I start out with! It will generally depend on the stone. Glad you liked it.
