- fastest response time (test-result in 1 second)
- left-handed or right-handed use
- thinnest probe (0.45mm) tests stones as small as 0.01 carat (1 point)
- can be used with batteries (included) or USB power (cable not included)

LIMITATIONS
This is the only diamond tester, that we have come across, that will detect the new "low-conductivity" Moissanites, which show up as diamond on other diamond testers. That's good! The disadvantage is that some synthetic diamonds show up as Moisssanite.

Disclaimer
All testers must be used in conjunction with the user's skill, knowledge and experience. Under no circumstances shall QUICKTEST be liable for direct or indirect loss sustained in connection with any item. Nothing is 100% accurate, you must understand the limitations of any tester you buy. We also suggest you regularly test known samples to check for any obvious faults.

Alternatives
Please note, none of these testers will distinguish natural stones from synthetic stones. "Synthetic" is a scientific term meaning 'made by man in a factory/laboratory to the same formula found in nature'. The two are usually indistinguishable, synthetic diamond is diamond (read about synthetic diamond testers and see our ARI and ARETE models).
The testers below are to distinguish diamond from non-diamond (simulant/imitation).

QUESTIONS & ANSWERS
Ask a Question-
Hi, is this better then Presidium 111 multi tester?
We were comparing the Presidium Multi Tester III and the SAM only last week.
At first they seemed exactly the same in both speed and accuracy. Then we tested a synthetic diamond and the Multi Tester III incorrectly showed it to be Moissanite every time; the SAM tester correctly showed it to be diamond every time (see our explanation of synthetic v. natural diamonds).

Hi, in what way will the Presidium Sam perform better than the Gemtrue Multi tester ?
When we’ve had ‘low conductivity’ Moissanites, this has been the only tester to correctly identify them, every time, instantly.
It’s more responsive, the instant result gives you the confidence that it's not "thinking" about the answer.
A customer visited and brought with him a selection of ‘difficult’ stones he had been testing on various other diamond testers. He said that the SAM was far better than anything he had tried. It’s certainly better than anything else we’ve tried. -
Hi, is this tester recognise CVD (man made dimonds)?
No.
That requires a very specialist tester, see ARI. -
Hi sir presidium SAM can work on rough stage diamonds and rough moissanites or only it can identify polished diamonds and polished moissanites please give me information I need to test rough diamonds and rough moissanites. In India now many rough moissanites its very confusing to identify the diamonds in rough stage. thank you
The SAM will work on small rough diamonds/Moissanites providing the probe can make good contact, ie the crystal must be clean and smooth, not crustated, coated or embedded in another mineral.
-
Hello, do you know if this can be used on set gems? E.g. a stone in a ring?
Yes, this tester is specifically for testing stones set in jewellery.
It also comes with a stone-holder for loose stones. -
i need a vat receipt as buying these through my business
A VAT receipt is included with every order. Normally we put it in the parcel but it can be emailed if preferred.
