Diamonds Tester - Gem Scanner

Diamonds Tester – Diamond & Gemstone Testing with AI Curious whether that ring or stone is a real diamond — or a moissanite, cubic zirconia, or glass? Diamonds Tester helps you find out. Point your camera at a diamond or gemstone and our AI gives an instant visual estimate of what it most likely is and how genuine it looks — then walks you through the real, at-home tests you can do yourself. 💎 Honest & upfront No phone app can prove with certainty that a stone is a real diamond. Our AI gives a visual estimate from a photo — a helpful guide, not a lab certificate or appraisal. That is exactly why the app also teaches the real tests and points you toward professional verification for anything valuable. 📸 Instant AI stone scan Snap or upload a photo. Get the likely stone type (diamond, moissanite, CZ, glass or another gem), a genuine / uncertain / simulant / synthetic reading, a confidence score, what the AI saw, any red flags, and clear next steps. 🔬 Real at-home tests (step by step) • Fog / breath test • Water / density test • Loupe (10x) inspection • Sparkle & fire test • Setting & hallmark check (10K, 14K, 585, 750, 925) • Honest heat / thermal explainer (a phone cannot run a real thermal test) 🔦 UV fluorescence guide Many natural diamonds glow blue under UV while most simulants do not. Our honest guided checklist helps you observe and understand it with a real blacklight (a phone screen cannot emit UV light, and we say so clearly). 📚 Gemstone library Real-photo profiles of Diamond, Lab-Grown Diamond, Moissanite, Cubic Zirconia, White Sapphire, Quartz and Glass — and how to tell them apart. 📐 The 4Cs, explained Cut, Color, Clarity and Carat in plain English, plus a glossary of the jewelry and lab-report terms you will actually see. 🧮 Value estimator A rough estimated price range from shape, color, clarity and carat — a ballpark to set expectations, not a formal valuation. 💬 Ask the Gemologist A built-in AI chat for your diamond and gemstone questions, honest about what a chat can and cannot confirm. Plus a gemstone identification quiz, saved scans and a personal collection, and a friendly community to share and discuss your finds. ⭐ Why choose Diamonds Tester? ✔ Instant AI visual estimate of diamonds and gemstones ✔ Real, step-by-step at-home tests — not just an app gimmick ✔ A UV fluorescence guide most apps skip ✔ Clear gemstone library with real photos ✔ The 4Cs and jewelry terms explained simply ✔ Value estimator to set price expectations ✔ Ask-the-Gemologist AI chat ✔ 30 free credits to start — no card required ✔ Honest about being an educational tool, never a fake “lab result” 👥 Perfect for shoppers checking a purchase, gift-buyers, resellers and thrifters, jewelry lovers, couples ring-shopping, students, and anyone simply curious. Disclaimer Diamonds Tester is an educational tool. Its AI provides a visual estimate from a photograph and its guides teach real testing methods — but neither is a laboratory certification, a professional appraisal, or a guarantee of a stone's identity, authenticity or value. No app or phone camera can definitively prove a diamond is real. For any purchase, sale, insurance or high-value decision, please rely on a certified gemologist, an accredited laboratory (such as GIA or IGI), or a trusted jeweler.
