Ethiopian Fire Opal Rough Gemstone Black Opal - Natural 04.10Cts. 11x12x07MM. Loose Gemstones SM04-21

As big as your pinky fingernail. Not polished , rough stone....no color

It’s very small and colorless

I mean, are you serious??? What was sent to me looks like a cloud of dirt! I don’t even think there is any gemstone at all in what I received. If there is, you certainly can not see it! This is false advertising at its finest. If I could give 0 stars, I would.

Small and what there was was almost all not opal.

I like the colors that change all the time especially when you look around the gem.

It is a nice opal but nothing like the picture. It has a little color and is mostly clear.

I've been ripped off, the gem I purchased was not the one pictured. The cover photo is a clean beautiful opal..and then I ordered and received an God awful looking opal. NOT clean and covered in matrix

Great for my collection
