I finished a triplet these days. It wasn't meant to be a triplet, but it ended like that.
When in Munchen, I bought an Ethiopian fire opal to make a pendant to Ina for her birthday. When I started to grind it, I realized there's no fire in it except the natural broken surface, so I had to add a back to make it doublet to thiner the opal. But when I wanted to polish the thin opal layer, I realized it's pretty crumble, so I added a top layer made of golden rutilated quartz from Brasil.
Here it is:
The fire in the opal is not first class (it was much nicer on the natural surface) but still there is some; you can see it better here:
Here's a side view:
And the back (pet wood from USA):
Thank you for looking.
