Native tin is an extremely rare element in nature, typically found as small, dull, silver-white grains in alluvial deposits. Collectors should look for heavy, soft metallic fragments that exhibit a bright luster on fresh surfaces, though they are prone to rapid tarnishing in air.
Is this native tin?
5-step field checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry to scratch native tin with a known reference. Native Tin sits at Mohs 1.5 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Native Tin leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Native Tin typically shows a metallic luster.
- 4Match the color rangeCompare against the expected color range: silvery-white, gray.
- 5Look at form & habitCrystal system: tetragonal. Typical habit: rarely found as crystals, usually occurring as small grains, flakes, or rounded nuggets in placer deposits.

Field-hunting tip
Look in placer deposits, occasionally in igneous or metamorphic rocks country — that is the host setting where native tin typically forms. If you start seeing cassiterite, gold, platinum in float, you are in the right ground. Field specimens usually show a rarely found as crystals, usually occurring as small grains, flakes, or rounded nuggets in placer deposits habit, so train your eye for that shape before scanning the outcrop.
