Minerals: How to Identify Minerals

To identify minerals, lead with measurable traits: Mohs hardness, streak, luster, and crystal habit — then rule out lookalikes. Open any mineral below for property checks, photo tips, and “how to identify …” depth; use the rock-types guide when your find is a rock mixture rather than a single mineral.

Quick field checks for minerals

Collectors win by stacking cheap tests: streak on unglazed porcelain, hardness vs glass or a knife, and whether cleavage planes repeat. Color is the least reliable cue — pyrite and gold, hematite and magnetite, fluorite and amethyst all need a second check. Each Batch-1 mineral page below lists the tells RockScan surfaces after photo ID so you can confirm before you file the specimen.
