Fluorite (fluorescent) Robertson Coll.

Item Description

Rust-red iron oxides preferentially included in some faces are a colorful and remarkable accent. Scattered modest bruising is certainy only a modest detraction to this fine large crystal. Purple fluorescence. Ex Kay Robertson Collection # 3232 and acquired in the mid-1960s.
