Mineral ini memiliki goresan kuning atau coklat muda, dengan kekerasan Mohs dari 3.5–4, dan gravitasi spesifik antara 3.9–4.1. Beberapa spesimen memiliki iridesensi merah di dalam kristal abu-abu; hal ini disebut "ruby sphalerite". Varietas kuning dan merah pucat hanya memiliki sedikit zat besi dan tembus cahaya.

Weisener (2002) observed increased rates of oxidation and increased acid consumption as a function of the amount of solid-solution iron in sphalerite [(Zn,Fe)S]. Apparent activation energies of 21–28 kJ mol –1 obtained at 25–85 °C are similar to the values reported by Rimstidt et al. (1994). Weisener et al. (2003) suggested that the production of polysulfide …

Sphalerite This mineral can be recognized by its striking resinous luster and perfect cleavage. The red variety is called "ruby blende" or "ruby zinc," while the dark varieties are known as "black jack."

Is Sphalerite Toxic. As with any mineral, the safety aspect of sphalerite is an important consideration, and while sphalerite rocks are generally non-toxic, they can contain traces of cadmium. In small quantities, cadmium is harmless, but there are some health concerns to be considered when large quantities of cadmium are ingested or inhaled.
