Is it a meteorite, or a meteor-wrong? Most unusual rocks people find are terrestrial. Meteorite Check helps you find out which you have, using a structured screening process built by people who handle real specimens every day. BEYOND GENERAL ROCK IDENTIFICATION This is not a generic rock identifier. It is a focused screening tool for one question: could this be a meteorite? It walks you through the same checks a specialist would run first, in plain language, and tells you honestly where you stand. HOW IT WORKS Answer a short set of physical checks: streak color, magnetism, density, surface features, interior metal, and more. The app rules out the common look-alikes first, then weighs what is left. Each check includes reference photos of real specimens and real meteor-wrongs, so you know exactly what you are looking at. HONEST BY DESIGN Your result is only as good as your answers, and the screening reflects exactly what you report, nothing more. No photo or kitchen-table test can classify a meteorite. Only a hands-on examination, and where needed laboratory analysis, can confirm one. A strong result here means your rock is worth a proper look. We tell you that plainly, and we tell you when a result is weak. OPTIONAL PHOTO ANALYSIS For a closer read, optional photo analysis examines the surface and any cut face of your specimen for the subtle signatures that point toward a meteorite and the disqualifiers that rule one out, then sharpens your result based on what it finds. A STRONG CANDIDATE? HERE IS THE NEXT STEP When a specimen screens as a strong candidate, the app produces a one page screening summary you can save and take to a laboratory. It records what was checked, what was ruled out, and the reasoning behind the result, so a lab can assess the specimen quickly. Screening is not confirmation. Only a hands-on examination and, where needed, laboratory analysis can identify a meteorite.
