The S setting is the ultra-sensitive setting and can only be used to test Micro-Diamonds. This setting will cause false readings if it is used to test objects weighing more than 0.2 grams. **Q: Why does my device barely respond when I test diamonds?Why not work?** A: The L setting is specifically designed for large diamonds. If you use this setting to test small diamonds, the device will barely react. **Q: What should I do if I don't know the exact size of the diamond?** A: You can start by testing with the M setting. The M setting is for testing diamonds between 0.5 and 1 carat. ## Frequently Bought Together - HMKIS Diamond Tester Pen, Professional Jewelry Diamond Tester with 60X Jewelry Loupe Magnifier, Diamond Selector for Novice and Expert (Non-Rechargeable) - Weigh Gram 200g Digital Pocket Gram Scale 0.01g Accuracy, 200g x 0.01g Mini Digital Grams Scale, Small Food Scale, Jewelry Scale, Ounces Grains Scale With100g Calibration Weight --- ## 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.co.za/products/306078742-hmkis-diamond-tester-pen-high-accuracy-jewelry-diamond-tester-60x](https://www.desertcart.co.za/products/306078742-hmkis-diamond-tester-pen-high-accuracy-jewelry-diamond-tester-60x) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-29*
