💎 Is your diamond real or fake? Find out in seconds.
Diamond Tester turns your phone into a smart, pocket-sized diamond checker. Snap a photo of any stone, ring or piece of jewelry and our AI gives you a fast real-vs-fake estimate — reading the sparkle, fire, facets and the tell-tale signs of a fake — then shows you exactly how to confirm it.
Buying an engagement ring? Checking an inherited piece? Curious about a stone in a drawer? This is the easiest way to tell a real diamond from a moissanite, cubic zirconia (CZ), white sapphire or glass imitation — no lab and no jeweler appointment to get started.

🚀 HOW IT WORKS

3. Get your real-vs-fake estimate — then confirm with the built-in home tests
✨ PERFECT FOR
• Engagement ring and jewelry shoppers
• Inherited, vintage and estate jewelry finds
• Resellers, pawn and second-hand buyers
• Gemology students and curious diamond lovers
💍 COMMON FAKES YOU CAN SPOT
• Moissanite — extra rainbow fire and doubled facet edges
• Cubic zirconia (CZ) — heavy, glassy sparkle with a flawless face
• White sapphire and white topaz — softer, greyer sparkle and little fire
• Glass, paste and rhinestone — bubbles, rounded facets and low brilliance
The app also explains natural versus lab-grown diamonds, so you always know exactly what you are holding.
Real diamonds have a look that is hard to fake: bright white-light return (brilliance), balanced flashes of colour (fire), razor-sharp facet edges and tiny natural inclusions. Simulants often give themselves away with an over-the-top rainbow, soft or doubled facet edges, air bubbles or a “too perfect” flawless face. Diamond Tester helps you spot these clues — and become a smarter, more confident buyer.
⚠️ IMPORTANT — PLEASE READ
A photo can NEVER certify a diamond. Brilliant fakes like moissanite and cubic zirconia can look incredibly real, so every result is a visual ESTIMATE for education and curiosity only — not a certified, professional or laboratory test. Always confirm with the home tests, and for anything valuable have the stone verified by a certified jeweler or gem lab (GIA / IGI). Diamond Tester does not grade, appraise or guarantee the authenticity or value of any stone.
