Overview Introducing the GemTrue APEX DK10300 — a professional-grade synthetic diamond tester engineered for the discerning jeweler, gem-laboratory technician, or appraisal specialist. Designed to keep pace with the evolving gem-market (CVD/HPHT synthetics, low-conductive moissanite, traditional natural diamonds, simulants like CZ/glass), the APEX delivers fast, reliable results in a compact, intuitive form. Whether you’re testing rings, pendants, loose stones or trade-show parcels, the APEX gives you confidence and clarity in your identification workflow. Key Features & Benefits “5-in-One” detection capability: Validates Cubic Zirconia (CZ)/Glass, Simulants (other gemstones), Natural Diamonds, CVD/HPHT/Type IIa synthetics, and Moissanite (including low-conductivity variants). Loose and mounted-stone compatible: Accurate testing on settings, earrings, pendants, and loose gems. Advanced optical + thermal conductivity technology: Combines thermal and optical cues for high-precision differentiation of synthetic vs. natural stones. Instant visual + audio feedback: Results appear clearly on a high-resolution display and audible alert for quick decision-making at the bench or counter. USB-C rechargeable lithium-polymer battery: No need for disposable batteries; based on manufacturer specs approx. 2 hours continuous use per full charge. Professional-grade packaging & portability: Supplied in a protective case with cleaning cloth, loose-stone holder, USB-C cable and manual. Compact and bench-ready. Ideal For Retail jewellers verifying incoming stones or mounted jewellery Wholesale operations quality-checking parcels of loose goods Gemological labs and mobile appraisal services Fine-jewellery repair benches or trade-show booths needing fast turnaround Usage & Care Notes Be sure to fully charge the unit before first use; low battery may reduce accuracy. Use only the supplied USB-C cable and a 5 V/0.5 A charger (does not support high-power “PD” fast-charging). Allow gemstones to cool between successive tests and wait for prior result to clear before re-testing. Heat buildup may affect accuracy. Clean the tester’s tip gently after periods of inactivity; remove dust/oil from stones with a dry tissue for accurate results. Unexpected or ambiguous results should be referred to a qualified gemologist for confirmation. Why Choose the APEX DK10300? The APEX DK10300 gives you a high-level testing platform without the prohibitively high cost of lab-only instrumentation. For the professional jeweler or gem-lab on the move, it combines portability, speed and capability — all in one unit. With the surge in synthetics (CVD/HPHT) and advanced simulants (low-conductivity moissanite), having a tester that keeps up with market developments isn’t a luxury — it’s a necessity.
