Gold Identifier
Who Publishes This
Gold Identifier is built and published by MD TECH. The app is available on the Apple App Store and Google Play, and everything on this site, the guides included, is written and maintained by the same team that builds the app.
You can reach us directly at app-support@md-tech.in. We answer support mail ourselves; there is no outsourced help desk.
How the Identification Works
When you photograph an item, the app runs an AI image analysis over what the camera can actually see: color, luster, form, surface texture, wear patterns and any stamps legible in the frame. From that it names the most likely item type, gives a confidence score, and explains what any visible hallmark means.
Separately, the app holds a reference database of hallmark and purity standards, and pulls live gold spot prices so the built-in calculator can convert a weight and a purity into a current value.
What We Will Not Claim
This is the part most apps in this category are vague about, so we would rather be blunt.
A photograph cannot measure metal content. No camera-based tool can, ours included. The app reads appearance and markings. It cannot see through plating, it cannot weigh an item, and it cannot distinguish a well-made tungsten-cored fake from solid gold, because those two look identical from the outside.
That means every karat figure and every value figure the app produces is an estimate. It is a fast first-pass screen and a genuinely useful reference. It is not an appraisal, not an assay, and not a substitute for either. When money or insurance depends on the answer, get an acid test or a free XRF scan at a jeweler. Our guides say the same thing, repeatedly, because it matters.
How the Guides Are Written
The guides are built from published, checkable standards rather than opinion: national hallmarking regulations and assay office marks, the millesimal fineness system, mint specifications for bullion coins and bars, and the standard physical and chemical tests used in the trade.
Where a test has a known failure mode, we say so in the same breath as the test itself. The magnet test does not prove gold, it only rules out ferrous metal. The density test fails on tungsten. The acid test marks the piece and only reads the surface. A guide that lists tests without their limits is worse than no guide at all, because it produces confident wrong answers.
Every guide carries a last-updated date. When gold market conventions, hallmarking rules or our own understanding change, we revise the guide and move that date.
Corrections
If you find something on this site that is wrong, tell us at app-support@md-tech.in and we will correct it. If you are a jeweler, assayer, refiner or dealer and something here does not match your bench experience, we especially want to hear it.
