Painite is one of the world's rarest gem minerals, first discovered in the Mogok region of Myanmar. It typically occurs as hexagonal prismatic crystals and is prized by collectors for its extreme scarcity and deep, saturated reddish-brown color.
Is this painite?
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 painite with a known reference. Painite sits at Mohs 8 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Painite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Painite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: dark red, brownish-red, orange-brown.
- 5Look at form & habitCrystal system: hexagonal. Typical habit: prismatic crystals.

Field-hunting tip
Look in marbles and skarns country — that is the host setting where painite typically forms. If you start seeing corundum, spinel, zircon in float, you are in the right ground. Field specimens usually show a prismatic crystals habit, so train your eye for that shape before scanning the outcrop.
