| SF-1: Fluorite, Jamesonite, Calcite
Sabinas mine, Sombrerete, Zacatecas
Specimen size: W: 6.0, D: 4.0, H: 5.0 cm
Description: pyramid-like grown fluorite crystals to 2 cm in size with cubic and dodecahedral faces. Countless hair-like jamesonite crystals to about 1 cm in length are included in the light-green and colorless fluorite. Due

Description: On the matrix rock (massive arsenopyrite-quartz-bornite) are sitting milky white quartz crystals up to 2 cm in length. Pseudo-cubic bornite crystals (max.
7 mm along edges) are perched on the quartz crystals. The bornite crystals are covered with a very thin spongy crust (a mixture of native silver and covellite); small wires of native silver grow from the bornite crystals. These bornite crystals represent the largest ones I have seen from this deposit.
