Ivanyukite-K is a rare titanium silicate mineral found primarily in the alkaline massifs of the Kola Peninsula. It typically forms small, pale bluish rhombohedral crystals or crusts within pegmatitic cavities, often requiring micro-analysis for definitive identification.
Is this ivanyukite-k?
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 ivanyukite-k with a known reference. Ivanyukite-K sits at Mohs 4, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Ivanyukite-K leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Ivanyukite-K typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: pale blue.
- 5Look at form & habitCrystal system: cubic. Typical habit: cubic crystals.

Field-hunting tip
Look in alkaline pegmatites country, the host setting where ivanyukite-k typically forms. If you start seeing microcline, aegirine, nepheline in float, you are in the right ground. Field specimens usually show a cubic crystals habit, so train your eye for that shape before scanning the outcrop.
