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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worth the price *by L***N on 28 May 2025* ### ⭐⭐⭐⭐⭐ Works amazingly well if you practice *by K***5 on 8 April 2025* ### ⭐⭐ No es tan confiable, muy caro para lo que es. *by M***O on 11 February 2024* El producyo aparenta muy buena calidad, pero no es lo que promete. Tengo casos en los que un diamante HPHT es leido como diamante cuando esta sobre la placa de aluminio suministrada y una vez montado en oro lo lee como Moissanita. Casos en los que pequeños diamantes naturales los lee como Moissanitas. Y casos en los que a las Moissanitas las lee como diamantes.. Aun limpiando, aun cambiando pilas, aun verificando angulo de toma, aun con todo lo que se recomienda hacer, lls errores de lectura son persistentes, por lo que no es confiable su uso. para eso, vale mas comprar un diamond selector de 150 pesos (conductividad termica) y un Moissanita terster de 150 pesos (conductividad electrica) y con menos del 10% de lo que vale este producto tienes los mismos o incluso mejores resultados de lectura, ya que con esos aparatos baratos si temgo lecturas persistentes de lo que se trata. ## 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.tw/products/263908439-multi-tester-iii](https://www.desertcart.tw/products/263908439-multi-tester-iii) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-05-23*
