CLASSIC ruby silver, mined in the late 1800s in Chanarcillo! A very showy specimen showcasing rare individualized crystals of proustite on matrix, in itself also rare as most are on massive lumpy proustite. Here we have real matrix of calcite crystals and rock. Also, as a bonus, a very nice old label! This specimen, with crystals to 1.5 cm, is beautiful from both sides. The proustite has great color and luster. There is some damage, unfortunately, but that is why its not 50k as well. Its all in context. Overall, though, I feel this is a very good cost-compromise in that you get a large specimen with freestanding crystals, matrix, color and luster without breaking the bank to do so. Such pieces are uncommon, in any event.
