Placer gold is native gold that has been weathered out of primary lode deposits and concentrated in stream beds or gravels by water action. It is typically found as rounded nuggets, flattened flakes, or fine dust, prized by collectors for its natural shape and high purity.
Is this gold placer?
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 gold placer with a known reference. Gold Placer sits at Mohs 2.5-3 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Gold Placer leaves a golden yellow streak.
- 3Read the lusterHold the specimen under a strong light. Gold Placer typically shows a metallic luster.
- 4Match the color rangeCompare against the expected color range: golden yellow, brass yellow.
- 5Look at form & habitCrystal system: cubic. Typical habit: nuggets, flakes, grains, wires.

Field-hunting tip
Look in alluvial deposits and stream sediments country — that is the host setting where gold placer typically forms. If you start seeing magnetite, hematite, quartz in float, you are in the right ground. Field specimens usually show a nuggets, flakes, grains, wires habit, so train your eye for that shape before scanning the outcrop. In the U.S., the densest reported localities are in New Hampshire — start trip planning there.
