Its performance is inconsistent, often failing to distinguish between diamonds and simulants effectively. This can lead to confusion and potential errors, especially when assessing valuable or delicate stones. The build quality is also lacking, with a flimsy design that feels less durable than expected. Frequent calibration issues can result in unreliable readings, requiring constant adjustments to maintain accuracy. The user interface is not as intuitive as one would hope, making the testing process more cumbersome than necessary. Additionally, the display is small and hard to read, which can be frustrating during detailed examinations. The overall functionality does not justify the investment, particularly when compared to other more reliable and accurate testers on the market. Customer support is reportedly slow to respond, which is a drawback if issues arise. For those serious about gemstone testing, it’s worth considering alternatives that offer better reliability and accuracy. Overall, the Diamond Tester fails to deliver on its promises, making it a less advisable choice for enthusiasts and professionals alike. ## Features - ALL-IN-ONE INSTRUMENT: The world’s first tester that tests for both colorless diamonds and moissanites in a single instrument.

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 ### ⭐⭐⭐⭐⭐ Ok *by F***S on August 14, 2026* Excelente ### ⭐ Disappointing Performance and Accuracy *by M***E on July 31, 2024* The Diamond Tester falls short in several key areas, making it a less reliable choice for those needing accurate gemstone assessments.

Turns out I was the weak link. After reading other reviews and watching the product videos, I realized I wasn’t putting adequate pressure on the stone. After being mindful of the stone cleanliness, probe angle, and pressure, I’m identifying stones with precision. This is a prograde device which does require practice and patience. I’m extremely happy with the purchase. ## 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.no/products/3228232-presidium-multi-tester-iii-pmut-iii-all-in-one-instrument](https://www.desertcart.no/products/3228232-presidium-multi-tester-iii-pmut-iii-all-in-one-instrument) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-17*
