Leopardite is a distinctively spotted variety of porphyritic igneous rock, primarily consisting of quartz and feldspar with manganese oxide inclusions. The dark, leopard-like spots are formed by the irregular staining of these manganese dendrites within the light-colored matrix. It is highly sought after by lapidary enthusiasts for its unique aesthetic when polished.
Is this leopardite?
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 leopardite with a known reference. Leopardite sits at Mohs 6-7, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Leopardite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Leopardite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: white, cream, brown, black.
- 5Look at form & habitCrystal system: trigonal. Typical habit: massive.

Field-hunting tip
Look in porphyritic igneous rocks country, the host setting where leopardite typically forms. If you start seeing quartz, feldspar, manganese oxides in float, you are in the right ground. Field specimens usually show a massive habit, so train your eye for that shape before scanning the outcrop. In the U.S., the densest reported localities are in North Carolina. Start trip planning there.
