Multi tester for diamond, Moissanite, white sapphire. Testerossa by Gemoro

As far as testing is concerned, the Testerossa is identical to the Ultratester 3+. including the same limitations, so please see the Ultratester 3+ for details. This is how it differs from the Ultratester 3+:: It has a larger carrying case than with the Ultratester 3+ It comes with a charging dock. Simply rest the tester in the dock to charge the batteries. This saves you from having to plug a cable into the tester.*   Included is a magnifier that can be clipped to the end of the tester to enable you to see the stone more clearly.  In addition to the display (the same as the Ultratester 3+) it speaks the results out loud. This is good for reassuring a customer (who can't see the display), or if you really don't want anyone to hear (e.g. checking stones at an auction viewing) you can turn the voice off.   * You do, of course, have to plug the charging dock into the mains. 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. Full support given for items you buy from QUICKTEST. Alternatives Please note, none of the testers listed below 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).    Model Tests mounted stones [1] Tests  Diamond Tests  Moissanite Tests Ruby /  Sapphire Other stones Diamond selector II, (DT-DS-crp) (works some of the time) ✔ ✔ Shows up as diamond ✘ No reaction on non-diamond Diamond selector II  (DT-DS) (cheap but works most of the time) ✔ ✔ Shows up as diamond ✘   No reaction on non-diamond Diamond Experior (best diamond-only tester) ✔ ✔ Shows up as diamond ✘ Non-diamond reads 'Other Stone' Moissanite tester by GemVue (Moissanite Plus) MOISS-4) ✔ ✘ ✔ ✘ You must only test stones you are certain are diamond SAM multi-tester (MULTI-SAM) ✔ ✔ ✔ ✔ Non-diamond reads ‘simulant’ Handheld presidium gem tester (GEMTEST-PGI) ✔ ✔ Shows up as diamond ✔ 31 stones Standard Presidium (GEMTEST-P2) ✔ ✔ Shows up as diamond ✔ 17 stones Presidium Duo gem tester (GEMTEST-DUO-II) [2] ✔ ✔ ✔ [3] Digital refractometer by Presidium (REFRACT-DIGI-PRESID) ✘ ✔ ✔ ✔ 55 stones Refractometer (optical not electronic) (Refract-L) ✘ ✘ ✘ ✔ Hundreds of stones [4] [1] All testers test loose stones but not all can test mounted (set in jewellery) stones.
