Phosphophyllite Gemstone & Information | Gemopedia by JTV | Gemopedia™

Phosphophyllite

Phosphophyllite gets its name from its phosphate content, and the Greek "phyllon," meaning leaf, reflecting its leaf-like perfect cleavage. This bluish, sea-green crystal is prized by collectors for its tranquil color, but is rarely faceted because of its soft, brittle nature. Yet, it represents a top prize among specimen collectors.
