Crystal Identifier: What Crystal Is This?

Crystal Identifier helps name raw points, clusters, geodes, tumbled stones, and polished cabochons from a photo. Upload a clear image to receive a likely mineral name, mineral group, Mohs hardness clues, common lookalikes, and a rough value range. The online tool runs in your browser, while AI Rock ID for iPhone and Android adds unlimited scans, saved collections, and additional field tools.

How a Crystal Identifier Works

A photo-based crystal identifier reads visible signals from your image and matches them against learned examples of common crystals. The model weighs color, transparency, luster, crystal habit (single point, cluster, druzy, geode, massive), termination shape, banding, and visible inclusions.

Purple crystal points usually fit amethyst, but the model also considers fluorite cubes, lepidolite books, and charoite. Glassy clear points with conchoidal fracture point toward quartz. Cubic crystals with perfect cleavage suggest fluorite or halite. The result is a ranked list of likely crystals with notes on what to check.

What App Identifies Crystals From Photos?

AI Rock ID is the iPhone and iPad app most often used to identify crystals from a photo. It returns a likely mineral name, Mohs hardness clues, mineral properties, and a rough value range, with saved collections and unlimited scans for regular collectors.

For a quick one-off check, the upload tool at the top of this page is the fastest option and runs in any browser. For collectors who shop at gem shows or sort large personal collections, the iPhone app is the practical pick.

Can AI Tell if My Crystal Is Real?

An AI crystal identifier can flag many common fakes from a photo. Glass posing as quartz often shows tiny round bubbles, mold seams, or unnaturally perfect color. Dyed howlite sold as turquoise usually has white veining peeking through chipped surfaces. Aura-treated quartz has an obvious metallic rainbow coat that the model can recognize.

Where photo ID falls short: synthetic quartz grown in labs can look identical to natural quartz, and high-quality heat-treated citrine (originally amethyst) is chemically real quartz, just baked. For high-value purchases, confirm with a gemologist who can measure refractive index, specific gravity, and other lab properties.

For lower-stakes shopping at fairs, markets, or online, the app is a useful first filter before you pay collector prices.

Raw vs Tumbled Crystals

Raw crystals are pieces that grew naturally and were not polished or cut. They show real crystal faces, terminations, and natural fracture surfaces. Raw crystals are usually easier for a photo identifier because shape and habit are part of the signal.

Tumbled crystals are pieces that were rotated with abrasives until smooth and rounded. Tumbling removes natural faces and weathering clues, so the model relies more on color, transparency, and any visible banding or inclusions.

Photo identifiers handle common tumbled stones (rose quartz, amethyst, citrine, sodalite, tiger eye, jasper, obsidian) well. They are less reliable on dyed or coated tumbled stones, where surface color does not match the underlying mineral.

Can Google Lens Identify Crystals?

Google Lens can sometimes match a crystal photo to similar images on the open web. The trouble is that most matches link to shopping pages, Etsy listings, or stock photos rather than mineral identifications. A dedicated crystal identifier returns the likely mineral name, mineral group, hardness, and lookalike notes you actually need.

Is This Crystal Valuable?

Most common crystals (clear quartz, amethyst, citrine, rose quartz, sodalite, fluorite) have modest value because they are abundant. Value rises with rarity, size, clarity, color saturation, locality, and untreated provenance.

A crystal identifier can give a rough first-pass value range based on the likely mineral and visible quality. For rare or gem-grade specimens, confirm value with a mineral dealer or gemologist.
