got one stone which was certified as a HPHT diamond from this lab.

It was a moissanite...
Not a good reference for them...

This is completely hearsay.
Let's see a copy of that report.
Let's see the stone described.

Call me a skeptic......cause I am. :|

No it is not. [-X
Had the stone and certificate in my hand and tested the stone.
It was moissanite. Either the lab or the seller did something wrong.

Because of that i opened this thread....

The weight itself would separate the 2....as would anything testing for HPHT.
You are implying fraud, and I wouldn't do that unless I could prove it, not just claim it.

Report copy? Listing weights and measurements
Stone in question? Listing actual weights and measurements

Sorry for that. I normally don´t keep certs or stones which I don´t buy.
In this case the weight is problematic, because the stone is set in a ring (which I did not mention).

I have a bad picture of the cert and of the ring which i took there.
So my conclusion is the cert is wrong or someone swapped the ring/stone.

He made big excuses and returned the ring to his seller, who tested the stone also to be moissanite (as he said). They now try to find out where the cert is coming from.

It was a short story for me. I got the info for a nice stone (setted) and went there to have a look.
So with 2 instruments (Diamond Combotester and Presidium Duotester) I found out that the stone is not what the cert said.
As I did buy a few stones in the last years from him I believed him he did not know, meaby he should test before he sells...

I was lucky, because normally I don´t take pictures of stones/Rings I don´t buy.
But this was the first time I stumbled upon a good looking cert which doesn´t fit to the stone.
If I get more information I will post it here.

How is your experience with certs? Do you often meet wrong ones?

In my years of comparing gems to reports, I have only found "sellers" to get mixed up.

Either buying stones and not verifying that the labs actually issued the reports, or mixing up the reports and giving a client the wrong one.

I hear the very rare "my synthetic alex was identified as natural" by GIA" Or "my orange grossular was IDd as Tsavorite"..... but I've never personally encountered something like this while appraising. Although I have encountered a few wrong reports given to a customer after a sale. :| A simple phone call fixed the problem.

Have you tried contacting this lab through this page
http://www.dia-labs.com/CONTACT

I'd be interested to hear their feedback.

Clarity??? lol that is new, HPHT Treatment cause clarity to go down not up!!!!
the whole thing looks phoney to me. their website/report/stone.....

just browse their website, at the buttom there is a US Phone number, most section is demo of the template, looks some rookie designer is making reports and the whole company. its not uncommon there used to be hundreds of fake gem labs

Clarity enhanced usually indicates lead glass filled which would be a different process than HPHT.
I don't believe the lab made that kind of a mistake. I think the moissanite is NOT the stone described in the report.
