- High Accuracy Thermal Conductivity Testing – HomeToDou professional diamond tester pen adopts advanced thermal conductivity technology and a high-precision chip,which can quickly and reliably identify real diamonds and distinguish them from common simulants like cubic zirconia,glass and crystal within 1 second.With stable performance and low error rate,it provides professional and trustworthy authentication results for jewelry testing,whether you’re checking personal collections or reselling items.
- Built-in 365nm UV Light for Fluorescence Detection – Equipped with a professional 365nm UV light,this HomeToDou diamond tester can clearly show the fluorescence color and intensity of diamonds,offering an important reference for further authenticity verification and quality evaluation of your gemstones.The UV light function also helps assist in screening moissanite (which has different fluorescence characteristics from natural diamonds),making your testing more comprehensive.
- Clear LED Indicator & Sound Buzzer Alarm – After 25 seconds of warm-up,the color-coded LED display (1-8 scale) shows precise testing readings, allowing you to clearly understand the detection results at a glance.When a real diamond is detected,the red indicator flashes continuously and the buzzer emits regular,clear alert sounds;for fake simulants,there will be no buzzer and the LED will stay on at a low scale,ensuring intuitive and accurate judgment without professional knowledge.
- Wide Testing Range for Small & Mounted Stones – This HomeToDou diamond tester accurately detects diamonds as small as 0.02 carats (2pt),perfectly suitable for both loose stones and mounted jewelry such as rings,earrings,necklaces and bracelets.Just touch the conductive metal panel on the tester with your finger during testing and keep the probe 90° vertical to the diamond surface to avoid metal interference,ensuring the most accurate test results every time.
- Complete Portable Kit for All Users – This compact pen-style testing set comes with a 60X LED magnifying loupe (for observing tiny details of gemstones),a durable protective carrying case (for safe storage and portability),1 x Tweezers,1 x Jewelry Scale Popular and a 9V battery (included,no additional purchase needed).Lightweight and easy to carry,it’s ideal for garage sales,flea markets,store checks,jewelry collection inspections and daily use,suitable for both beginners and professional jewelers.
- User-Friendly Design & Energy-Saving Function – The HomeToDou diamond tester features a simple one-switch operation,with clear power and ready indicators to guide you through the testing process easily—no complicated setup required.It also has an automatic power-off function to save battery power when not in use for a long time,extending the service life of the battery and the tester itself.The smooth pen grip and detachable probe cover also enhance the overall user experience,making it comfortable to hold and use for extended periods.
