would an appraiser be able to tell??

Let''s say you bought an uncertified diamond and it was lab enhanced in some way, but they didn''t tell you that. If you got that diamond appraised later, would the appraiser be able to tell the diamond was lab enhanced if he wasn''t looking for it?

I would hope a good appraiser could pick up on a CE stone but I suppose it depends on how hard they are looking.

Laser drill holes are fairly easy to see. Fracture filling can be another story, but it is my understanding that the substance used to fill the void reflects a certain color when the diamond is viewed just right. There was a great link to a website with pictures of this...do a search for CE diamonds on PS and it should come up. I would think that an appraiser is trained to look for this...

Edited to add: check out this link where PSers talk about fracture filling

An appraiser, a decent appraiser, ALWAYS "looks for it". We are born suspicious and curious. It is a trait of a good appraiser to nit pick and see what others don't much care about. If there is a CE treatment, we think we will see it without being prompted.

It is possible to attempt to treat a diamond and basically fail to improve it, yet a tiny residual of the treatment might be visible upon very careful examination. however, in terms of value, a failed treatment does not count as a treatment. A 1% success would be no better than a 0% success. A 100% success, a 85% success, even a 20% success would all qualify as treated. If the treatment is obviously detectable with 10X, then it is deemed treated. If the treatment is superficial and barely visible at 10x, then we'd report the attempt and say that other than a residual amount, the stone was unsuccessfully treated.

I know this is a little confusing, but without complexity, we'd have no appraising. Complexity makes for expertise........Life's good.
