Crystal Scanner
AI crystal and stone identifier - point your camera at a rock, get an answer
About Crystal Scanner
Crystal Scanner answers a question that is genuinely difficult without training: what is this rock. Mineral identification traditionally depends on hardness tests, streak plates, specific gravity measurements and a practised eye for crystal habit, none of which are available to someone who has just picked up an interesting stone on a beach or inherited a box of unlabelled specimens. Image classification handles this category unusually well, because minerals have distinctive visual signatures in colour, lustre, transparency and crystal structure. Point a camera at the specimen and the tool returns an identification.
Rather than presenting one general classifier, the site is organised into more than twenty-five dedicated identifiers, each tuned to a specific material: amethyst, agate, aquamarine, chalcedony, citrine, emerald, fluorite, garnet, jade, lapis, malachite, moonstone, onyx, opal, pearl, rhodonite, ruby, sapphire, selenite, sodalite, topaz and tourmaline, alongside broader tools for stones, rocks, minerals, gemstones, diamonds, gold and even meteorites. That structure matters in practice: if you already suspect what you are holding, running the specialised identifier for that material gives a more focused result than a general classifier hedging across every mineral in existence. The service is free to use in the browser.
Choose the identifier that matches what you are trying to determine. If you have no idea what the specimen is, start with the general crystal, stone or mineral identifier; if you suspect a particular material, go straight to that identifier for a tighter answer. Upload or capture a photograph of the specimen, ideally in good natural light and against a plain background, since lustre and true colour are exactly the signals the model relies on. The AI analyses the visual characteristics and returns an identification along with information about the material. Because the identifiers are separate, comparing results across two or three related tools is a reasonable way to sanity-check an ambiguous specimen.
- •25+ Specialised Identifiers - Separate models for amethyst, agate, aquamarine, citrine, emerald, fluorite, jade, opal, ruby, sapphire, tourmaline and many more, rather than one general classifier
- •General Stone and Mineral Tools - Broad crystal, rock, stone, mineral and gemstone identifiers for when you have no starting hypothesis
- •Precious Material Identification - Dedicated diamond, gold and pearl identifiers for the materials where getting it wrong is most consequential
- •Meteorite Identifier - Covers the specific case of suspected meteorites, which are commonly misidentified terrestrial rocks
- •Photo-Based Analysis - Works from an ordinary photograph, requiring no hardness kit, streak plate or specialist equipment
- •Browser Based - No app installation; the identifiers run directly in a browser on desktop or mobile
- •Free to Use - No subscription or credit system gating the identifiers
- •Cross-Checking Workflow - Running a specimen through several related identifiers gives a practical confidence check on an uncertain result
For rock and mineral collectors working through unlabelled specimens, hikers and beachcombers curious about something they picked up, and crystal enthusiasts who want to verify what a seller told them they were buying. Teachers and parents get an accessible way to make geology tangible for children. Jewellery buyers can get a first-pass read on a stone before commissioning a proper appraisal. That caveat is worth stating plainly: for anything of real monetary value, photographic identification is a starting point and not a substitute for a gemologist with the specimen in hand.
