Is It Celestine or Celestite?

Описание: This is an exceptional celestine specimen. Celestine is a strontium sulfate mineral but early (very awesome) Spanish specimens were believed to be barium rich as strontium had yet to be discovered at that time. Celestine is a relatively soft mineral, brittle, not useful for jewelry or any of the like. But otherwise it's still really pretty! Especially this one with its awesome crystal lattice! NFS
