Kottigite (rare arsenate - excellent) Mullane Coll.

Item Description

Kottigite is a VERY RARE mineral from the famous Mina Ojuela and this an outstanding specimen. A fabulous, 1.4 cm, starburst of highly lustrous, platy, brassy blades with a hint of green is aesthetically set on the scultpural, sturdy gossan matrix and has the very nifty accent of a little brother starburst. Kottigite is related to legrandite, of which, Mina Ojuela is renowned. This striking piece is from the small finds of the 1960s and 70s. Kottigite is an Ojuela classic and is very difficult to obtain in this super quality. Ex Dennis Mullane Collection.
