Andradite on Chalcopyrite with Quartz

Here is an interesting combination piece. Host rock consisting of a mixture of andradite, chalcopyrite and epidote(?) opens to a vug lined with brick red andradites on which a quartz and 1.5cm andradite formed. Collected in 1974. A one off that you find in self collected collections! Ex Ken Roberts collection.

Locality: Garnet Hill, Calaveras County California

Composition: multiple species
