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. Review: Inaccurate diamond tester - This diamond tester does not work and it is very inaccurate it reads everything as simulated even stones that I know that are genuine gia diamonds my employee tested a customer's diamond and had to tell them it was imitation they were so upset and the woman actually started crying this damaged my business beware before you buy this product ## Features - ALL-IN-ONE INSTRUMENT: The world’s first tester that tests for both colorless diamonds and moissanites in a single instrument. Powered by 3 AAA batteries. - EASY TO USE DESIGN: Ergonomic handheld design with a rubberized anti-slip grip for easy handling. Light and portable with a convenient carrying case. - THINNEST RETRACTABLE PROBE TIP: Retractable probe tip that ensures consistent pressure against the gemstone during testing for more reliable results.

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 ### ⭐⭐⭐⭐⭐ Works amazingly well if you practice *by K***5 on April 8, 2025* Initially I thought this multi tester was unreliable.
