The GemTrue APEX is an advanced 5-in-1 synthetic diamond tester built for jewelers, gemologists, and diamond appraisers who need fast, accurate identification of today’s Synthetic (so called, Lab Grown) diamonds. In a single handheld device, the APEX distinguishes:
Natural Diamonds
CVD / HPHT synthetics (including Type IIa)
Moissanite (including low-conductivity stones)
Cubic Zirconia / Glass
Other simulants
Why professionals choose the APEX:
True 5-in-1 detection — one device replaces multiple testers.
Intuitive color touchscreen for clear, instant readouts.
Automatic calibration — no manual setup before testing.
Tests loose and mounted stones with a metal loose-stone holder.
Rechargeable built-in 3.7V / 2200mAh Li-ion battery with USB-C charging — no disposable batteries.
Compact & portable (180 x 40 x 25 mm) for the bench, showroom, or travel.
In the box: APEX tester, metal loose-stone holder, cleaning cloth, protective bag, user manual.
Backed by GemTrue’s ASSURE-tested detection technology, the APEX gives you confident, repeatable results on natural vs. Synthetic (so called, Lab Grown) diamonds — the essential screening tool for the modern gem trade.
The Apex is a 5-in-1 tester that separates natural diamond, CVD and HPHT lab-grown diamond, moissanite and other simulants in one instrument, so a single pass answers both questions a parcel raises: is it diamond, and is it natural?
