Would you trust this lab diamond tester?

[nala]

So this pawn shop uses this tester. I see it online but I don’t see any reviews. Would you trust this tester? I want to buy an eternity ring and supposedly all the diamonds are natural yet not one shows fluorescence. I know that the lack of fluorescence does not indicate that it is lab, but of 19 or so stones—not one.
Here is the tester.

Hi nala,
At this point I consider all melee to be lab unless I’m getting them from one or two cutters we’ve been working with more than 15 years.
I agree that seeing fluorescence is “comforting”…. But we also agree that the lack of fluorescence is not conclusive.
I have not used that specific tester.
I will be glad to reach out to growers I know Monday to get the lowdown on it.

How large are the stones?

I should add that I did not see any inclusions either so it is the most flawless natural eternity band I have ever seen, or it is a lab band. Sigh. I guess if it is too good to be true…

If they are naturals, it’s an expensive piece. We’re not talking melee.
A price too good to be true seems a red flag.
Speaking as a diamond dealer….. many of us are ……less than honest. I see it all the time. I’m very concerned that sellers will take advantage of consumer lack of knowledge on labs and their prices
I guess it’s not a well established seller?

It’s a chain of pawn shops. I have been buying from them for over a decade and they are as trustworthy as my knowledge of their items, lol. Let’s just say that the employees who take in these pieces are not experts and they rely on machines to test. I have never seen this machine in any other pawn shop and my google search indicates it’s a Fairly new machine. The other pawn shops that I frequent have been using a more sophisticated one.

I’ll be glad to check it out Monday!

Nala get one of these - if none of the stones fluoresces, then its a fake.
Just watch out though because some colorless synthetics will fluoresce very pale white.
You should get +60% of natural diamonds lighting up in relative darkness in mainly very bright white, blues and greenish tinges, an occasional orange.

Just back from vacay, I have been busy as a one legged man in an ass kicking contest...haven't had a chance to check out alternatives....
BUT
1) Garry- the link shows a not available item
2) While I agree that there's a fair percentage of stones that will fluoresce....the lack of a stone showing fl is NOT conclusive proof they are lab.
Other things in this specific case- like a super low price- seem to be more useful as evidence......but who knows.....

 

[Rockdiamond]

then its a fake.

Ummmm
I love you Garry....but the word "fake" is totally unacceptable in this instance.
If they were man made, they are still REAL diamonds.....
An inconvenient truth
