$350 · Opal Welo 6.9 Karats embeded butterfly or moth

I have for sale a 6.9 Karat Welo African Opal. A variety of good colors from red to deep purple, lots of fire in this one. 1 inch & 3/8 long and 15/16 of an inch wide. This would make a beautiful pendant I suppose. Too big for a ring. This opal appears to have a butterfly or a moth within it which makes it a bit unusual of course. Not just an average opal. There have been stories on some amazing Welo opals in the past, one being what looks like a complete kelp bed. It is hard to get a photo but this opal has a well defined wing structure that looks like a butterfly wing to me and the shape of the stone lends to the shape of a butterfly. I have had this for many years but have decided to sell it at this time. I think the price is reasonable considering the rarity of finding a stone like this one.
