Rose agate is a microcrystalline variety of quartz characterized by delicate pink to rose-colored bands or translucent layers. It is typically found in volcanic cavities or sedimentary nodules where silica-rich fluids deposited layers over time, often featuring beautiful botryoidal or banded structures.
Is this rose agate?
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 rose agate with a known reference. Rose Agate sits at Mohs 6.5-7, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Streak: white.
- 3Read the lusterHold the specimen under a strong light. Luster: vitreous.
- 4Match the color rangeCompare against the expected color range: pink, rose, white, reddish.
- 5Look at form & habitCrystal system: trigonal. Typical habit: banded, botryoidal, massive, nodular.

Field-hunting tip
Where it forms: volcanic vesicles and sedimentary geodes. If you start seeing quartz, calcite, goethite in float, you are in the right ground. Typical habit: banded, botryoidal, massive, nodular. Train your eye for that shape before scanning the outcrop. In the U.S., the densest reported localities are in Oklahoma, New Mexico. Start trip planning there.
