Raite is a rare mineral typically found as fibrous, yellow-to-brown acicular needles or radiating aggregates. It is almost exclusively found in the complex alkaline pegmatites of the Kola Peninsula in Russia, often associated with other exotic titanium-bearing silicates.
Is this raite?
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 raite with a known reference. Raite sits at Mohs 2-3, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Raite leaves a yellowish-white streak.
- 3Read the lusterHold the specimen under a strong light. Raite typically shows a pearly luster.
- 4Match the color rangeCompare against the expected color range: yellow, brown, orange-yellow.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: acicular crystals, fibrous aggregates.
Often confused with
Raite vs. its common look-alikes, and how to tell them apart in the field.
How to tell apart: Apatite is the harder of the two (Mohs 5 vs. 2-3); streak differs, so Raite leaves yellowish-white, Apatite leaves white; luster reads pearly on Raite and vitreous on Apatite.
How to tell apart: Streak differs, so Raite leaves yellowish-white, Astrophyllite leaves golden-brown; luster reads pearly on Raite and submetallic on Astrophyllite.
Often found alongside raite
Minerals reported to co-occur with raite. Spotting these in float or country rock is a strong cue you are in the right ground.

Field-hunting tip
Look in alkaline igneous rocks, specifically pegmatites in nepheline syenites country, the host setting where raite typically forms. If you start seeing aegirine, nepheline, eudialyte in float, you are in the right ground. Field specimens usually show a acicular crystals, fibrous aggregates habit, so train your eye for that shape before scanning the outcrop.
