Is that the same as not distinguishing between genuine or imitation?** A: Yes, and no. Imitation can be like, if they colored a Sapphire to be a Ruby. So, if you buy a Ruby, and it tests Sapphire, it might be Sapphire. You will also want to buy the Presidium Refractometer for a better accuracy (I own both). However, even with both tools, it takes a keen eye, and training to truly know what you're looking at. However, both tools have successfully identified Diamond and Moissanite for me. (Back to the issue at hand). Natural is mined, where as synthetic is lab grown. This generally means that the hardness index will be very similar to the real thing. If you find imitation, it can be anything from a different stone that's been colored, all the way to colored/dyed glass. **Q: Can i buy extra tips for my presidium i already bought** A: You can buy new probes for it. **Q: What is the newest version? And what batteries/adapter** A: yes both batteries and adapter, this is the newest version ## Frequently Bought Together - Presidium Instruments Gem Tester II (PGT II) Now with Assisted Thermal Calibration (ATC) for Identifying Diamonds/Moissanites and Common Colored Gemstones - ET-18 Mizar Gold Tester Battery Operated Electronic Gold Karat Purity Value 10K 14K 18K Tester --- ## 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.jp/products/247006042-presidium-instruments-gem-tester-ii-pgt-ii-now-with-assisted](https://www.desertcart.jp/products/247006042-presidium-instruments-gem-tester-ii-pgt-ii-now-with-assisted) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-03*
