Sometimes the stone is dirty and needs a cleaning. This can throw off results. Also, my unit is getting returned when I have a suitable replacement. It sometimes takes 3 or more tries to get it to register. Clean the stone and try touching it with a firm but not point grinding pressure a few times and if it doesn't work try another tester. Assuming of course you know the diamond is real. **Q: why one is 17.00 and other cost 265.00 same dis tester** A: By cheap get cheap **Q: How can I get a replacement tip?** A: You can get it replaced from manufacturer, fill out the return form. ## Frequently Bought Together - Presidium Multi Tester III (PMuT III) All-in-One Instrument for Testing Diamonds, Moissanites and Diamond Simulants - Honoson 3 Pack Diamond Tweezers Gem Stone Jewelry Locking Tweezers Stainless Steel Diamond Claw Holder Beads Ball Grabber Jewelers Pick up Tool Tongs for Jewelry Making(Claw and Tweezers) --- ## 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.at/products/3228232-multi-tester-iii-pmut-iii-all-in-one-instrument-testing](https://www.desertcart.at/products/3228232-multi-tester-iii-pmut-iii-all-in-one-instrument-testing) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-26*
