Mogovidite is a rare titanium-bearing garnet species characterized by its dark, often near-black appearance. Collectors typically find it in alkaline complexes, where it forms distinct dodecahedral crystals associated with nepheline syenites and related igneous rocks.
Is this mogovidite?
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 mogovidite with a known reference. Mogovidite sits at Mohs 7 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Mogovidite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Mogovidite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: black, brown.
- 5Look at form & habitCrystal system: cubic. Typical habit: dodecahedral crystals, granular.

Field-hunting tip
Look in alkaline igneous rocks country — that is the host setting where mogovidite typically forms. If you start seeing nepheline, aegirine, titanite in float, you are in the right ground. Field specimens usually show a dodecahedral crystals, granular habit, so train your eye for that shape before scanning the outcrop.
