✨ What makes Selenite special?
- Water is built into its structure: two water molecules form an essential part of every Gypsum formula unit rather than merely filling cracks or pores.
- Its broad layers separate easily: perfect cleavage allows clear crystals to divide into thin sheets that transmit a soft, moonlike glow.
- Its softness contrasts with its scale: Selenite measures only 2 on the Mohs scale, yet stable geological conditions can produce crystals several metres long.
