RM3588   Astrophyllite
K2NaFe2+7Ti2(Si4O12)2O2(OH)4F
  -  9. Silicates

A particularly aesthetic specimen from this important locality with thick, platy crystals with a metallic luster radiating from a central portion on matrix. This structure gives it its name, from the Greek άστρον ("astron") for "star" and φύλλον ("phyllon") for "leaf," alluding to its star-shaped spray pattern and micaceous appearance. Very good size.

Size: 9.6 x 7.7 x 4.8 cm.
Main crystal: 25 mm.
Classic locality
