Keep in mind that you MUST allow the "lamp" to power up and you MUST be holding the item with your fingers. This device will not determine genuine gemstones (i.e. rubies or sapphires) nor distinctions in metals (i.e. gold, silver or steel). So it will not determine if rubies, sapphires or turquoise are real. The only true way to do that is through a reputable jeweler. They have devices (light refractors) and experience to make those determinations but it may cost you for them to provide that information. I hope this helps. **Q: Does it come with instructions for testing turquoise, rubies and saphires?** A: I only tests diamonds, it was misleading in the description **Q: What is the difference between the black and multicolored tool?** A: The difference would be what the tool is capable of measuring. It measures the hardness of the stone. If a real diamond, it will light up and beep. Precious stone light it up in the mid area range. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by D***I on 1 June 2025* Good ## Frequently Bought Together - Dupeakya Professional Diamond Tester, Gem Tester Pen Portable Electronic Diamond Tester Tool for Jewelry Jade Ruby Stone - WELLZEER Keychain Magnet for Testing Brass,Keychain Pocket Magnets for Purse with Strong Magnetic Rare Earth Neodymium,Gold,Silver, Jewelry,Ferrous Metals Test Magnet (2PACK-D12mm) --- ## 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.be/products/265343296-dupeakya-professional-diamond-selector-ii-gold-testing-pen-portable-electronic](https://www.desertcart.be/products/265343296-dupeakya-professional-diamond-selector-ii-gold-testing-pen-portable-electronic) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-18*
