A field guide that admits what it can't tell you.

Point your camera at a stone, a crystal, or a piece of jewelry. RockLense gives you a likely match, the look-alikes it cannot rule out, and care information that has actually been checked.

A RockLense scan result identifying an amethyst cluster, showing a confidence level and the look-alikes it cannot rule out.

Most identifier apps tell you what you want to hear.

A photograph cannot separate natural stone from dyed, treated, synthetic, or imitation material. Glass, resin, lab-grown crystal, and coated specimens routinely look identical in a picture. Any app that answers with confidence is either guessing or lying.

RockLense answers with a likely match and then tells you, every single time, what that match might actually be instead.

“The purple colour zoning and hexagonal terminations are consistent with amethyst. Even so, a photo cannot rule out dyed quartz, a treated specimen, or a manufactured imitation, so this remains a visual resemblance rather than an identification.” An actual result, unedited

What it does

Three kinds of scan, one honest answer.

Add a single photo or several angles. Answer a few optional questions about colour, weight, or whether it scratches glass — they sharpen the result, and you can skip them.

Stones & crystals

Tumbles, towers, rough minerals, clusters, and cut specimens.

Jewelry

Rings, pendants, and bracelets — including hallmarks and maker's marks, read as claims rather than proof.

Shop labels

Photograph a vendor card and RockLense compares what the label claims against what the photo actually shows.

Care you can act on

The safety notes are written by a person.

Whether something is safe in water, fades in sunlight, or dissolves in an ultrasonic cleaner comes from a curated database of over 200 stones — not from freeform AI output.

  • ·Water, sunlight, and cleaner safety for every matched stone
  • ·Explicit hazard warnings for material you should not cut, grind, or dry-brush
  • ·Look-alikes named on every result, so you know what to rule out

Getting care advice wrong ruins a specimen. Getting a hazard warning wrong is worse than that, which is why those particular sentences are not generated.

Private by default

Your collection never leaves your phone.

  • ·No sign-up. No name, no email, no account to create.
  • ·No tracking and no ads. There is no analytics or advertising code in the app at all.
  • ·Location is stripped from every photo on your device before it is sent.
  • ·Photos are not stored. They are analysed and discarded; your saved collection stays local.

How it is paid for

Every scan is a real AI analysis, so scans use credits.

New users start with credits included — enough to work out whether the app is useful before spending anything. There is no subscription wall in front of the collection you have already built.
