[Precision & Safety] Our professional diamond tester combines an LCD display and LED indicators for clear, instant readings. Engineered for rapid and secure gemstone verification, this diamond selector tool guarantees zero damage to jewelry during operation. Trusted by jewelers, collectors, and gem enthusiasts, it delivers unmatched accuracy for diamonds and simulants like cubic zirconia (CZ). Compact and user-friendly, it offers exceptional value as both a workspace essential and a thoughtful gift for gemology enthusiasts.
[Effortless Gemstone Verification] Simplify testing with the HMKIS Diamond Tester Pen's one-touch functionality. Power on the device, gently place the probe on the stone's surface, and await the audio-visual result. Authentic diamonds trigger alerts above "9" on the display with audible confirmation, while non-diamonds (e.g., glass, CZ) yield no response. Ideal for quick checks on rings, loose stones, or vintage jewelry, this gemstone tester requires no technical expertise—perfect for hobbyists and professionals alike.
[Smart Calibration for Reliable Results] Optimize accuracy by adjusting the diamond selector's settings based on gem size. For stones >1.0 carats, activate one green LED; 0.5 carats require two LEDs, while intricate cuts or small gems (e.g., melee diamonds) need 3-4 LEDs. Position the probe vertically and avoid button contact during tests to prevent errors. Note: This thermal conductivity-based diamond tester may emit high-frequency alerts on metals due to similar heat-transfer properties—always follow guidelines to avoid testing on skin, liquids, or non-gem materials.
[Advanced Thermal Conductivity Technology] This gemstone tester distinguishes diamonds from imitations by analyzing heat dispersion rates. Metals trigger false signals due to overlapping conductivity, so avoid accidental contact with bands or settings. For best practices, test clean, dry stones on the included platform. If the pen flashes or shuts off, recalibrate settings or check probe alignment. A dedicated testing surface minimizes interference from ambient temperatures, ensuring consistent performance.
[User-Centric Features & Package Contents]: Select the appropriate carat mode via the +/- buttons before scanning. Maintain skin contact with the rear sensor panel to stabilize readings—improper handling may skew results. The kit includes a USB-rechargeable diamond tester pen, 1-meter charging cable, anti-slip testing base, and illustrated manual. Compact and travel-ready, it's a must-have for auctions, estate sales, or jewelry workshops. Store in a dry, room-temperature environment to prolong probe lifespan.
