Schneebergite is a rare antimony oxide mineral that typically occurs as an alteration product of antimony-bearing ores in hydrothermal veins. It is most easily identified by its characteristic octahedral crystal form and resinous luster. Collectors prize it primarily as a rare mineralogical species found in historic mining districts.
Is this schneebergite?
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 schneebergite with a known reference. Schneebergite sits at Mohs 5-5.5, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Schneebergite leaves a yellow streak.
- 3Read the lusterHold the specimen under a strong light. Schneebergite typically shows a resinous luster.
- 4Match the color rangeCompare against the expected color range: yellow, yellowish-brown, brown.
- 5Look at form & habitCrystal system: cubic. Typical habit: octahedral, granular, massive.
Often confused with
Schneebergite vs. its common look-alikes, and how to tell them apart in the field.
How to tell apart: Streak differs, so Schneebergite leaves yellow, Stibiconite leaves white; luster reads resinous on Schneebergite and dull on Stibiconite.
How to tell apart: Luster reads resinous on Schneebergite and earthy on Bindheimite.

Field-hunting tip
Look in hydrothermal vein deposits country, the host setting where schneebergite typically forms. If you start seeing stibnite, quartz, calcite in float, you are in the right ground. Field specimens usually show a octahedral, granular, massive habit, so train your eye for that shape before scanning the outcrop.
