Phoshophyllite | Gemopedia

Phosphophyllite gets its name from its high phosphate content and the Greek name for 'leaf' because this stone has a unique leaf-like cleavage. Phosphophyllite is sought after by collectors for its sea-like bright blue-green color. This gemstone is seldom cut because it is rare and easily broken during the cutting process.
