This halite–sphalerite specimen from the Empire State Zinc Mine #4 in the Balmat district of New York displays a striking balance of clarity, color, and contrasting mineral textures. Water-clear halite crystals rise in an ice-like cluster with sharply defined faces, each reflecting light with a crisp, glassy brilliance characteristic of the locality.

Warm golden sphalerite crystals accent the halite surfaces, adding depth and tonal contrast, while subtle calcite associations reinforce the classic Balmat paragenesis. As the piece shifts under natural light, the halite’s internal clarity and reflective planes alternate between transparent glow and sharp specular flashes, while the sphalerite reveals its resinous luster and rich amber color.

Weight: 136 g (0.30 lb)
Size: 66 × 52 × 52 mm (2.60 × 2.05 × 2.05 in)

A meaningful addition for collectors who appreciate the distinctive sulfide–halide mineral combinations from Balmat, especially specimens displaying both transparent halite and intact sphalerite crystals from documented mine levels.
