  • Know exactly what your find is worth with an estimated value range for every specimen, from beach pebbles to gem show pickups.
  • Distinguish genuine gold from pyrite or real diamonds from simulants using specialized tools for gold, diamond, and fossil identification.
  • Turn a child's mystery rock into a learning moment with a simple photo—no expertise needed to classify igneous, sedimentary, or metamorphic specimens.
  • Get comprehensive geological data for teaching or study—formation type and Mohs hardness delivered in seconds from a single clear photograph.
  • Identify trail-found rocks, beach pebbles, or museum-quality crystals with the same AI that analyzes color, luster, grain size, and fracture patterns against thousands of known types.
  • Confirm a diamond's authenticity by uploading a photo of raw, cut, or simulated stones—no scratch tests or special equipment required.
  • Discover if your fossil find is an ammonite, trilobite, or shark tooth using the dedicated fossil identification tool.
  • Upload JPG, PNG, WebP, or HEIC images up to 50MB and get accurate results even from dull specimens—just wet the surface to highlight colors and grain patterns.

Frequently Asked Questions

Rock Identifier.io is an AI powered application that helps to identify different types of rocks, crystals, minerals or stones from an uploaded photograph. The advanced AI technology in the app analyses features such as color, luster, crystal structure, grain size, and fracture patterns, comparing them against a massive reference set to provide the user with an accurate identification.
Rock Identifier.io recognizes different types of rocks, crystals and other geological specimens by analysing features from a user uploaded photograph. These features include color, luster, crystal structure, grain size, and fracture pattern. The AI technology in the application then matches these features against a reference set of thousands of known rock and mineral types to identify and classify the specimen.
When a rock is identified by Rock Identifier.io, the user receives comprehensive information about the specimen. This includes the name of the rock, its type classification (igneous, sedimentary, metamorphic), its Mohs hardness, how it was formed and an estimated value range.
Yes, the Rock Identifier.io can provide an estimated value range for the identified rock. This adds an exciting possibility for users to discover if the rocks they've found could possibly have a notable monetary worth.
Rock Identifier.io is designed to identify a multitude of different rocks, crystals and minerals. This includes common finds such as beach pebbles and trail found rocks, as well as more unique discoveries like gem show pick-ups and children's mystery rocks.
Yes, Rock Identifier.io is designed to work with a variety of geological specimens. Regardless of whether it’s a rock, crystal, mineral or stone, as long as it has discernible characteristics that can be captured in a photograph, Rock Identifier.io is capable of identifying it.
The Rock Identifier.io includes several specialized tools for focused identification. This includes a Crystal Identifier, Stone Identifier, Gemstone Identifier, Mineral Identifier, Fossil Identifier, Diamond Identifier, Gold Identifier, and a Rock Value Estimator.
A wide range of individuals can benefit from using Rock Identifier.io. This includes hobbyists, collectors, students, teachers, and geology enthusiasts. Essentially, anyone who has a curiosity about rocks, crystals, minerals, and stones can find the application immensely useful.
In Rock Identifier.io, users can upload JPG, PNG, WebP, and HEIC images of their specimens. The maximum file size is 50MB. The photograph should ideally be taken in such a way that it allows the AI to analyze the key features of the specimen, which include its color, luster, crystal structure, grain size, and fracture patterns.
To get the best possible identification from Rock Identifier.io, it’s recommended to use a clean, well-lit photograph shot straight-on so that the surface of the specimen fills the frame. If the rock appears dull, you may wet it first to better highlight colors and grain patterns. Using natural light and brushing off any loose dirt can also significantly improve the accuracy of the identification.
Rock Identifier.io determines the Mohs hardness of the identified specimen by applying its advanced AI technology to analyze visual cues. However, a user can confirm this hardness with a simple scratch test at home.
Yes, the Rock Identifier.io does offer a tool specifically for identifying gold. This can help distinguish genuine gold from other substances like pyrite that can often be mistaken for gold.
Yes, Rock Identifier.io can be used to identify common macrofossils such as ammonites, trilobites, and shark teeth. However, microfossils or fragmented specimens might be more challenging for the system to identify confidently.
It does, Rock Identifier.io offers a Diamond Identifier capable of distinguishing raw, cut and simulated diamonds. However, remember that for formal gemstone grading, a certified gemologist is still required as AI cannot measure refractive index from a photo.
Rock Identifier.io's AI inspects the photograph along several parameters. These include color, luster, grain size, fracture pattern, and transparency. The system then cross-references these parameters against a massive database of known rock and mineral types to arrive at an identification.
Yes, Rock Identifier.io is designed to let users identify the type of rock they have from just a photograph. However, for optimal results, taking a clear, straightforward photo under natural light works best.
Absolutely, Rock Identifier.io is a user-friendly application that can easily identify mystery rocks found by children. Kids just need to take a clean, clear photograph and the AI will match it to a vast reference set of known rock and mineral types.
Yes, Rock Identifier.io is an extremely useful tool for geology students and teachers. It rapidly provides accurate, comprehensive data about various geological specimens, making it a super practical resource for learning and teaching.
Rock Identifier.io is highly reliable for hobbyists and collectors. The AI technology analyses the specimen's features comparing them with a vast reference database, and gives an accurate and quick identification. However, for high-value specimens, it is recommended to also consult a geologist.
The Rock Identifier.io's AI compares the uploaded images against an expansive database that consists of thousands of known rock and mineral types. This massive reference set allows Rock Identifier.io to analyze each uploaded image and provide a highly accurate identification.
