Eosphorite and Collinsite on Rose Quartz

Item Description

Taquaral is located in Itinga, Brazil and is well-known for its fine quality phosphate minerals, including some excellent examples of Eosphorite. This piece is a beautiful association of this classic material featuring fine quality bladed "sword"-shaped crystals of gemmy/translucent golden-brown colored Eosphorite measuring up to 6 mm, associated with "sprays" of off-white colored Collinsite measuring up to 6 mm sitting on attractive pink Rose Quartz matrix. No major damage that I can find, and the presentation is excellent. A very attractive and rarely seen example from this famous specimen-producing area in Brazil.
