Pink pearls, typically associated with the Queen Conch, are calcareous concretions rather than true minerals. They are highly sought after by collectors for their unique flame-like surface structure and distinct salmon-pink color.
Is this pink pearl?
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 pink pearl with a known reference. Pink Pearl sits at Mohs 2.5-4, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Pink Pearl leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Pink Pearl typically shows a pearly luster.
- 4Match the color rangeCompare against the expected color range: pink, salmon, rose.
- 5Look at form & habitTypical habit: spheroidal.

Field-hunting tip
Look in biogenic country, the host setting where pink pearl typically forms. If you start seeing aragonite, calcite in float, you are in the right ground. Field specimens usually show a spheroidal habit, so train your eye for that shape before scanning the outcrop. In the U.S., the densest reported localities are in Iowa. Start trip planning there.
