QUESTIONS & ANSWERS
Ask a Question-
Will this test for jade
When you test a stone on this tester, the display gives the answer as a selection of possible stones. This is because the readings overlap, see our chart .
As you notice,a "jade" reading is unlikely to be spinel, it can't possibly be glass, chrysoberyl, topal ruby/sapphire or diamond. But it could be one of ten other gemstone groups. That is how gem testers work, they give you possibilities not an absolute answer, and it's up to you to decide which of the tester's "possibilities" apply. This particular tester is good because it will filter the results by colour. So if the tester suggests the reading could be one of five stones, select "green" and it might reduce the selection to two or three.
In real life it's not that complicated. If you collect jade you would not test a deep blue cabachon or a white sparkly stone or a semi-translucent figurine - you would know these cannot be jade. -
can it identify moissanite from diamond?
No.

Why don`t you have for sale Presidium Adamas, will you bring it? 2. If I buy and deliver in Romania, will I benefit from the warranty? How long is the international warranty? 3. If I buy the products, they will be subject to customs duty? 4. I would like some advice, I want to buy Presidium Gem tester in combination with Presidium Adamas. Would other devices be needed to identify stones and diamonds in jewelry (not at a professional level)? Thanks!
ADAMAS available to special order. We don’t sell this because the Presidium SAM is better.
