Magnesiohögbomite-2N3S is a rare complex oxide mineral belonging to the högbomite group, often appearing as dark, metallic-lustered tabular crystals. It is primarily found in high-grade metamorphic rocks such as marbles or granulites. Due to its scarcity and similarity to spinel, identification often requires professional geochemical analysis or precise optical testing.
Is this magnesiohögbomite-2n3s?
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 magnesiohögbomite-2n3s with a known reference. Magnesiohögbomite-2N3S sits at Mohs 6-7 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Magnesiohögbomite-2N3S leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Magnesiohögbomite-2N3S typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: dark brown, black, reddish-brown.
- 5Look at form & habitCrystal system: trigonal. Typical habit: tabular hexagonal crystals.
Often confused with
Magnesiohögbomite-2N3S vs. its common look-alikes — and how to tell them apart in the field.
How to tell apart: Spinel is the harder of the two (Mohs 8 vs. 6-7).
How to tell apart: Corundum is the harder of the two (Mohs 9 vs. 6-7).
How to tell apart: Streak differs — Magnesiohögbomite-2N3S leaves white, Manaccanite leaves black; luster reads vitreous on Magnesiohögbomite-2N3S and submetallic on Manaccanite.

Field-hunting tip
Look in metamorphic rocks country — that is the host setting where magnesiohögbomite-2n3s typically forms. If you start seeing spinel, corundum, magnetite in float, you are in the right ground. Field specimens usually show a tabular hexagonal crystals habit, so train your eye for that shape before scanning the outcrop.
