Review: Works amazingly well if you practice - Initially I thought this multi tester was unreliable. 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: Disappointing Performance and Accuracy - The Diamond Tester falls short in several key areas, making it a less reliable choice for those needing accurate gemstone assessments. 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.

## Questions & Answers

**Q: how do you calibrate it?**
A: Calibration is not needed as far as I know

**Q: Placing on diamonds and having no response, what does that mean?**
A: I have used this unit and had the same response on known diamonds.  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.
