Size is 2.5 inches and weighs about 248 grams.

Tetrahedral quartz on sphalerite is a mineral formation where quartz crystals, shaped like pyramids, grow on or around sphalerite, a shiny black or brown mineral. The clear or milky quartz contrasts with the darker sphalerite, making the combination visually striking. This formation is often valued by collectors for its unique shape and the contrast between the two minerals, showing how they form together in specific geological conditions.
