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.

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.
Download Diamonds Tester today and get an instant AI read on any diamond or gemstone — then learn to check it yourself the way the pros do.
