AURA GEMS Natural Black Opal Oval Shape-Ethiopian Opal Gemstone Wholesale Lot-Healing Crystals-DIY Jewelry Making Bulk Gemstone Deal (2 Piece Pack Of, Oval Cabochon, 8x6x4mm)

Beautiful little stones. I'm a beginner making jewelry but these are beautiful stones. Will reorder from this seller.

Beautiful and genuine black opals that are perfect for making rings

I ordered two different types of opal. The black opal was supposed to be 8*6*4. The traditional opal was purchased as 5*7. The black stone is smaller than the other stone. It should be bigger not smaller. It also has no opal coloration inside. It looks like a black stone. I am severely disappointed.

The tiny opals shown in the advertisement had lots of bright color. (The second photo is magnified 10x.) The ones I received are practically black, even under bright light. It'll be a challenge to mount them to look like anything except boring black plastic or glass.

So much prettier than I expected for cost. Out of the box, they look like onyx… just black stone. Hit them with some light and they explode into little universes that you can’t stop staring at. Will post more pics when I get them into settings. Recommend!! I’m ordering more from this seller.

Just what I ordered very nice.

These black opals were amazingly beautiful so small though such small amount for the money I do recommend this product

Not much color in all of them.
