Manganokhomyakovite is a rare member of the eudialyte group found primarily in alkaline massifs. Collectors typically look for its distinct rhombohedral crystal form in nepheline syenite environments. It is highly valued as a rare mineralogical study specimen due to its restricted distribution.
Is this manganokhomyakovite?
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 manganokhomyakovite with a known reference. Manganokhomyakovite sits at Mohs 5-6 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Manganokhomyakovite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Manganokhomyakovite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: brown, reddish-brown, yellowish-brown.
- 5Look at form & habitCrystal system: trigonal. Typical habit: rhombohedral crystals, massive.

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