A rare stone, sphalerite, is essentially an ore of zinc and is known as zinc blende. It is known to a limited audience as an unusual gemstone, which makes it an exquisite piece for a collection.
Many of the greatest sphalerites on sale today on the international market are stones cut from old stocks of raw materials mined in the Spanish Aliva mine. Only a small fraction of the crystals mined before 1989 in Spain have good transparency.
Description of sphalerite gemstone:
The stone comes in yellow, orange, green, and red shades.
Place of mining:
Jewelry sphalerites are mined only in Spain (orange and yellow) and Bulgaria (green). In the rest of the deposits of other countries, only collectible crystals are found.
Bright yellow, orange, and yellowish-green specimens without zoning and inclusions are highly prized. The cost directly depends on the quality of the cut, which requires great skill of the cutter because, in addition to the low hardness, sphalerites are also very fragile stones.
Large cut samples of zinc blende are of great gemological rarity. This is the dream of many collectors. Also, rare sphalerite gemstone has amazing optical properties: its dispersion value surpasses the diamonds one by more than 3.5 times! This is generally the most "sparkling" of any existing natural stones!
Sphalerite, which forms interlayers with magnetite, quartz, chalcopyrite, and galena, is used in handicrafts. Decorative products and souvenirs made from banded minerals are unusual and beautiful.
Due to its unstable physical properties, low hardness, and high fragility, the mineral is rarely used in jewelry. Sphalerite gemstone is cut in cabochon and inserted into rings, pendants, earrings, men's rings, and bracelets, but the original appearance of stones in jewelry is short-lived.
This factor became the reason that artificially created sphalerites of green and yellow colors began to be inserted into jewelry. More often, exclusive specimens of sphalerite are exhibited in collections. Depending on the shade, some faceted specimens of the mineral are similar to zircon and garnet.
The amount of impurities in the composition of a gem affects its color and appearance. Depending on these criteria, the mineral is divided into the following varieties:
Cleiophane is an iron-free mineral in the form of transparent crystals of light yellow, honey, or greenish-yellow color.
Marmatite is a stone that got its name from its mining site in Marmato, Peru. It is a black, opaque type rich in iron.
Pribramit is a semi-transparent sample of yellow shades with a high percentage of cadmium (up to 5%).
Brunckite is earthy crystalline sphalerite with a pale yellow to whitish hue.
Marasmolite is a dilapidated structure of marmatite, characterized by fragility and a small amount of iron in its composition.
Honey blende is amber yellow sphalerite.
Ruby blende is an orange-red stone.
