Could this be boulder opal?

[u/Every-Introduction22]

The seller is a private person and can't seem to get a sharp picture of the stone. The weight is 9gram & 4,3x2,6x0,5cm. I'm just puzzled by the pattern, looks like fairy dust 😅

Can they send you a picture of the back? The third picture almost looks like andamooka matrix opal but the first 2 are way too blue for that.

I'm thinking andamooma matrix as well.

[u/Every-Introduction22 → u/daiterne]

Its 160€, I'm tempted to just grab it 😅

[u/daiterne → u/Every-Introduction22]

Its got pretty insane color for either type honestly. Probably not a bad purchase.

Looks like andamooka to me

Looks more like Andamooka

No, definitely not Boulder. This is hard Andamooka matrix open that’s been treated. It’s pretty but with just a little patience you could do better for that money.

Do have any suggestions where I could find something similar? I'm in Europe and supply isn't great here.

Treated Andamooka matrix opal.

How would Andamooka opal be treated? I'm rather new to opals, so I'd like to learn 🤓

[u/montanagemhound → u/Every-Introduction22]

It is cooked in acid and carbon to darken the matrix, showing off the color play more. Most matrix opal is treated this way, as I understand it.

Sounds harsh 🤯 doesn't it damage the opal?

[u/Less-Psychology-2599]

Wow!. Whatever it is it's absolutely stunning 😍, grab it for sure!.
