Grossular and Zircon Mineral Specimens from the York River Skarn Zone Near Bancroft, Ontario

Purple zircons such as this one were a super rare find at the York River Skarn Zone near Bancroft, Ontario, Canada.       Here is a large cluster of grossulars, clinopyroxene and brucite.   

Grossular/ Clinopyroxene York River Skarn Zone, near Bancroft, Ontario, Canada. This now closed site produced some fabulous garnets in the late 1990's for a brief time. I removed the primary mineralized pod over the period of an entire summer and still have some quality pieces. These are all thumbnail specimens mounted in perky boxes. They are nothing short of fantastic. Bright orange/ red garnets in combination with dark green clinopyroxene (likely diopside). Crystals range from a few millimeters to well over 2 cm. The luster is the best you can find, the form very good and the contrasting colors make each of these superior specimens. The garnets are transparent and translucent with internal fractures and the clinos are opaque. Top shelf pieces from a location that is now a provincial park and off limit to collecting.  Be sure to read the article on this site.
