Bournonite!
A group of exceptional bournonite specimens from a recent find in Bolivia. Many of these pieces have lusters that are about as good as one could hope for from the species, and display excellent cogwheel form. Bournonite from this mine tends to have somewhat tarnished, altered surfaces, or crystals that are somewhat thinner. In fact, the last time this mine produced particularly good lustrous crystals was 2012-- there was another find of large blocky crystals around 2015, but they didn't have much going for them as far as luster was concerned, nor did I see any on matrix.
