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, 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.
