Spharelite
Answer. Sphalerite sells between $20 and $200 per carat. The value is dependent on many factors, but cut, color, and clarity are the biggest ones. You need to find a qualified appraiser who is familiar with rare gems. The stone must be inspected in person to get any kind of accurate idea of its value. Sphalerite is usually reserved for collectors. Sphalerite is the most important ore of zinc. Around 95% of all primary zinc is extracted from sphaleritic ores. However, due to its variable trace element content, sphalerite is also an important source of many minor metals, such as cadmium,, gallium germanium, and indium. Gemstone use

Sphalerite IIa, hosted in biotite schist, occurs as coarser, irregular-shaped areas (Fig. 5a), thus being distinct from type Ia. This type is typified by inclusions of pyrrhotite and lesser chalcopyrite (Fig. 5b).
