A gorgeous and colorful Tsumeb large miniature (only technically a small cab size) with two generations of Dioptase covering a fluorescent Calcite matrix. The second generation of larger, lustrous, gemmy Dioptase crystals up to 1.3 cm rests upon a bed of GEMMY, mm-size Dioptases. The piece shimmers and sparkles like green sugar candy, and is ten times better in person than the pics can portray. One crystal in upper-left-center is broken, hence the piece looks like it should be valued higher, but we priced it at under my cost to make up for that and give a deal. It is a showy specimen in this size range!
