Lovdarite is a rare beryllium silicate mineral primarily known from highly alkaline pegmatites. It typically forms attractive, clear-to-white tabular crystals or radiating sprays that are highly prized by systematic mineral collectors.
Is this lovdarite?
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 lovdarite with a known reference. Lovdarite 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. Streak: white.
- 3Read the lusterHold the specimen under a strong light. Luster: vitreous.
- 4Match the color rangeCompare against the expected color range: colorless, yellow, yellowish white, white.
- 5Look at form & habitCrystal system: orthorhombic. Typical habit: prismatic, radial.
