ðļ How to Get the Most Accurate Identification
Getting great results from Rock Identifier is easy. Here are a few tips to make sure your photo gives the AI everything it needs.
Use natural lighting
Photos taken outdoors in daylight give the most accurate colors and clearest detail. Avoid flash photography where possible, as it can wash out luster and subtle hues.
Show a clean surface
Dirt and mud can obscure a rock's true identity. If possible, rinse or brush off the stone before taking a picture to reveal its actual surface and crystal structure.
Get close and in focus
The more detail visible in the photo, especially crystal shapes and cleavage planes, the more accurate the identification.
Show a fresh break
Many rocks look completely different on a weathered exterior than on a fresh interior break. If you have a broken face, make sure to photograph it.
Multiple photos improve accuracy
If you have several photos of the same rock from different angles, try uploading the clearest one first. Different angles reveal different identifying features.
ð§ Did You Know? Fascinating Geological Facts
Every identification comes with facts like these â discover something new every time.
There are over 5,000 known mineral species, but only about 100 are common enough to be frequently encountered.
The oldest known rocks on Earth are the Acasta Gneisses in Canada, which are over 4 billion years old.
Diamonds and graphite (pencil lead) are made of the exact same element: pure carbon.
A pumice stone is a volcanic rock that is so light and full of air bubbles that it can actually float on water.
Obsidian is volcanic glass that cools so rapidly that crystals don't have time to form.
The Earth's inner core is a solid sphere made mostly of iron and nickel, and it is as hot as the surface of the sun.
Some minerals are fluorescent and will glow in vibrant colors when exposed to ultraviolet light.
Quartz is piezoelectric, meaning it generates an electrical charge when mechanical pressure is applied to it.
Gold is so malleable that a single ounce can be beaten into a sheet covering 100 square feet.
Fossils are rarely the actual bone. Over millions of years, the organic material is replaced by minerals, turning it into solid rock.
