Description

Point your camera at any rock, mineral or crystal to get its name, its Mohs hardness and an estimated value range in seconds. Real geology data, not a one-word guess.

WHAT EVERY SCAN GIVES YOU

The specimen name plus its scientific name and chemical formula

A confidence rating (high, medium or low) so you know how sure the result is

An estimated value range in USD for the exact piece in your photo

Category: igneous, sedimentary, metamorphic, mineral, gemstone, fossil or meteorite

Mohs hardness, composition, color, luster and streak

WHAT IS IT WORTH

Most identifier apps stop at the name. Rock Identifier adds an estimated value range for the piece you photographed, shown as a typical market range such as $28 - $40. Use it to sanity check a shop price, decide which trail finds are worth keeping, or find out what is already sitting in your display cabinet.

GEOLOGY-GRADE DETAIL

Formation: how the specimen forms and what conditions create it

Typical locations: where it is commonly found around the world

Identifying features: the field tests that separate it from look-alikes

Common uses, plus a fun fact for every specimen

ASK ABOUT YOUR SPECIMEN

Ask follow-up questions in plain language, answered about the exact piece you scanned. Ask why the streak matters, how to tell it apart from a common look-alike, or whether it is a good candidate for tumbling.

YOUR COLLECTION, ARCHIVED

Every scan is saved on your device with its photo, name, date and estimated value. Search the archive, revisit an old find, and share any result. Your collection becomes an inventory.

WHO IT IS FOR

Rockhounds and hobby collectors logging trail finds and tumbling batches

Parents and kids answering "what is this rock?"

Crystal and gemstone buyers checking what a piece is and roughly what it is worth

Earth science students and teachers working on hardness, composition and formation

HONEST LIMITS

An internet connection is required. Identification runs on a server, so there is no offline mode.

Values are estimates for guidance only. This is not an appraisal, a certification or a laboratory assay, and it is not a resale guarantee.

Hardness and streak are the typical published values for the species. Your phone does not test them.

Photograph a clean, well-lit specimen. Wet, dusty or heavily polished pieces are harder to read.

Results are AI-generated and can be wrong. The confidence rating tells you when to double-check a result.
