Hey guys,

I know that heat treatment is not detectable by standard gemological testing, but are there any advanced tests out there that can conclusively prove heat treatment in aqua? or are there any indications generally?

Thank you!

Not to my awareness.
But, an aqua having a green modifier is an indication of no treatment.
