Ideal for professionals, collectors, and jewelry business owners.【Easy One-Button Testing】Simply turn on the pen, gently touch the gemstone tip, and wait for the audible alert. Real diamonds trigger a reading above 9 with both light and sound signals; no reaction indicates a fake stone like cubic zirconia.【Adjustable Setting for Stone Size】Easily adapt to different gem sizes using the carat adjustment button: activate 1 light for diamonds over 1.0 carats, 2 lights for 0.5 carats, and 3–4 lights for small or finely-cut stones.【Reliable Thermal Conductivity Detection】The tester uses advanced thermal conductivity sensing to distinguish diamonds from imitations. Note: metals may trigger high-frequency sound due to similar conductivity—always follow correct testing procedures and avoid use on metal, skin, or liquids.【Convenient & User-Friendly】Designed for effortless use with clear visual and audio cues. For accuracy, always touch the rear panel during testing and ensure proper tip contact—flashing or shutdown may indicate incorrect .Specification:Model：KD-MD1Working voltage：3.3-4.2VWorking temperature：10-40℃Product size：158*45*21mm Adapter (not included in this instrument)Adapter voltage：120-240V Data cable plug：type-cAdapter power：1A/2AAdapter output voltage：5VInternal lithium battery parameters Model：14500Voltage：3.7VCapacity：800mAhPacking List:1 x Diamond Tester Pen1x 1M USB Cabel1 x Testing Platform1 x User Manual ## Features - Easy onebutton testing turn on, touch gemstone tip, real diamonds trigger reading above 9 with light and sound signals - Reliable thermal conductivity detection distinguishes diamonds from imitations, avoid use on metal/skin/liquids - Adjustable setting for stone size via carat button 1 light for over 1.0ct, 2 for 0.5ct, 34 for small/finelycut stones - Intuitive and safe with LCD display and LED indicator for precise, easytoread results without damaging genuine diamonds - Convenient and userfriendly with clear visual and audio cues, touch rear panel during testing for accuracy ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0G6LK18GH | | Brand | Generic | | Brand Name | Generic | | Color | Black | | Included Components | 1 x Diamond Tester Pen, 1x 1M USB Cabel, 1 x Testing Platform, 1 x User Man | | Manufacturer | Generic | | Number of Items | 1 | | Part Number | PONelq2534878202O | | Power Source | Battery Powered | | Style | Rechargeable with UV Light, LCD Display, LED Indicator, One-Button Testing, Carat Adjustment Button, Type-C Data Cable Plug, Compact Design (158*45*21mm) Style Rechargeable with UV Light, LCD Display, LED Indicator, One-Button Testing, Carat Adjustment Button, Type-C Data Cable Plug, Compact Design (158*45*21mm) See more | | Style Name | Rechargeable with UV Light, LCD Display, LED Indicator, One-Button Testing, Carat Adjustment Button, Type-C Data Cable Plug, Compact Design (158*45*21mm) | | Unit Count | 1.0 Count | ## Images ![Rechargeable Diamond Tester Pen with UV Light High Accuracy Electronic Jewelry Gem Selector for Novice and Expert Use - Image 1](https://m.media-amazon.com/images/I/61C4ughZcfL.jpg) ![Rechargeable Diamond Tester Pen with UV Light High Accuracy Electronic Jewelry Gem Selector for Novice and Expert Use - Image 2](https://m.media-amazon.com/images/I/51QAypTBgVL.jpg) ![Rechargeable Diamond Tester Pen with UV Light High Accuracy Electronic Jewelry Gem Selector for Novice and Expert Use - Image 3](https://m.media-amazon.com/images/I/51HBeFOBG0L.jpg) ![Rechargeable Diamond Tester Pen with UV Light High Accuracy Electronic Jewelry Gem Selector for Novice and Expert Use - Image 4](https://m.media-amazon.com/images/I/512o4OmHAKL.jpg) ![Rechargeable Diamond Tester Pen with UV Light High Accuracy Electronic Jewelry Gem Selector for Novice and Expert Use - Image 5](https://m.media-amazon.com/images/I/51lyHvc+3jL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.es/products/806636892-rechargeable-diamond-tester-pen-with-uv-light-high-accuracy-electronic](https://www.desertcart.es/products/806636892-rechargeable-diamond-tester-pen-with-uv-light-high-accuracy-electronic) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-05-26*
