Hello, I was wondering if anyone could help me.

I am looking to purchase a diamond tester and was wondering which ones are best. Ideally I would like to purchase a diamond / mossainite tester in one, around 150$ at maximum if this isn't enough money then just a diamond tester.

I appreciate any advice. Thanks in advance.

That said, I've never actually seen this tool. I rather like Presidium tools and am very happy with mine but they are quite a bit more expensive.

I did see that one but some of the coments on it below are a bit scary as to wether the item will work properly.

Thanks for your help though, I have seen the presidium ones is that the ones you use, are they good? and which would you recomend? Thanks again.

We've been happy with the Presidium MultiTester.

Thanks for the reply Barry, but yeah the multi one costs 249$ from what I can see, that's quite a lot more than I had in mind, any other suggestions for around 150$ at max?

You got it what you paid...

I hope you don't mind me asking - but why do you need a diamond tester?

It's a gift

I would go for the quality tools, espeically if this is a gift for someone who is actually going to use it. If budget is the issue, drop out the moissanite test and get a presidium thermal tester. Moissanite isn't that hard to spot with a loupe anyway (actually cz's aren't that hard either but it's nice to have confirmation). Ceres makes good tools as well. You'll be at about $100 and get something that he/she can rely on.

Thanks again for your help!

I have been searching and have come across these: Presidium Diamond Mate A, Ceres CZeckpoint Diamond Tester, Ceres Reliance Diamond Tester-AAA Battery Operated and Ceres Reliance AC Diamond Tester with Built In Adaptor 110V, was wondering which you would recommend sorry to be a pain

Also I discovered this one Gemvue multitester with case, was wondering if you had any idea if that one is any good as it does do both and is in budget!

Thanks a lot for your help and time I do appreciate it, I have no real idea with this just know someone who will be very happy to receive one! You mentioned it is easy to distinguish between a diamond and moissanite, may I ask how?

Moissanite is birefringent: each ray of light entering the stone is "split in two". This is easily observable as a doubling of the facet lines when looking through the stone in any direction except the optic axis (one particular direction - and normally moissanite is cut so as to minimize the visibility of this effect through the table, so just tilt the stone or look through the sides!).

This effect is not present in a diamond (or a CZ), and once you see it it's pretty easy to spot it again, unless the stone is very small or set in a very enclosed setting.

I also found this one which appears to also be made by presidium any thoughts: [url][url]http://www.igem.com/a-source-diamond-moissanite-tester-as2-1t.html[/url][/url]

Also thanks for the explanation on moissanite
