Diamond / Moissanite Dual testers


#1

I would appreciate any feedback from Orchidians who are using a
single device which tests for Cubic Zirconia AND Moissanite. There
are several on the market, and they all seem to cost around $250
U.S… I would like your input before I buy one. Have you seen any
trade magazine articles comparing the various models?? Thank you,

Thermal & Electric conductivity testers. These dual mode models are
very popular now and the best one for the money & WARRANTY is called
the Diamonite it cost $219.00. You could order this by phone 800 221
4812 or email

The diamondnite uses a 9 volt battery commonly available and it is
made in USA.

Cheaper ones may be made in China.

David, Moissanite testers are actually sort of a scam as moissanite
is doubly refractive and diamond isn’t. Most diamond substitutes
(not synthetics) are easily distinguishable under a microscope if you
spend the time to look at them properly. I wouldn’t waste the money.

Can’t help you with the testers much, but just out of curiosity, why
bother with anything other than a good loupe? Both stones are easy
to identify under ten power… Moissanite especially, since it’s
double refractive. You get doubled facet images when you look at
back facets THROUGH the stone… Once you see what to look for, it’s
pretty obvious. I know that stores may not want to train sales
people in this, thinking it may be complex, but frankly, it really
isn’t that hard to do…

Just my two cents.

Hi Dave, I have the Gemonics model “The Veriteer” and has worked
pretty well for me. I got it from Rio about a year and a half ago.

I want to thank everyone who took the trouble to write about this. I
am well aware that Moissanite is doubly refractive, and know how to
look for that.

I am a G.G. (since 1972) and between my partner and myself, we have
almost 50years experience in this trade. I am reasonably sure that I
can ALWAYS spot a “non-diamond” but I want the gadget to backup to my
experience, so I STILL plan to buy one. Using one is a whole lot less
grief than making a mistake would be. David Barzilay, Lord of the
