All solids and only 1 doublet: Black, White, Jelly Opal Collection: 110 Total Stones
Bought this collection from a minor in Australia when I was over there on a gold hunt around 1990. I have over 110 total pieces of varing sizes in this collection. Black, White, and really nice Jelly (transparent) Opals.

3 pictures to show you a few of the varing sizes of opals included in this collection. All solid stones except one Doblet. One very large Black Opal Solid (57.65 ct. or 11.53 grams or .0465 oz.). Let me know and I will send all the pictures. Assoreted Sizes and Colors.

Just make me a reasonable offer.
