What are Sphalerite Crystals and what is Sphalerite used for?
Sphalerite crystals are a mineral composed of zinc sulfide (ZnS) and iron (Fe).
It crystallizes in the face-centered cubic zincblende crystal structure, which is a member of the hextetrahedral crystal class.
The chemical formula of sphalerite crystals is (Zn,Fe)S;
the iron content generally increases with increasing formation temperature and can reach up to 40%.
All natural sphalerite contains concentrations of various impurities,
which generally substitute for zinc in the cation position in the lattice.
The most common cation impurities are cadmium, mercury and manganese,
but gallium, germanium and indium may also be present in relatively high concentrations.
The material can be considered a ternary compound between the binary endpoints.
Cadmium can replace up to 1% of zinc and manganese is generally found in sphalerite with high iron abundances.
Sphalerite has an important role as an ore for many metals such as zinc, lead and
copper due to its abundance and wide distribution throughout the world.
Its crystal habit makes it an attractive gemstone when cut into cabochons or faceted stones.
What are Sphalerite Properties?
Physical properties of sphalerite crystals are quite unique, making it easy to distinguish from other minerals.
It has perfect dodecahedral cleavage, meaning that it can be split into six planes.
This is a rare property among minerals and makes sphalerite highly sought after.
Additionally, the mineral has a distinctive resinous luster and a reddish-brown streak in darker varieties.
Sphalerite also transitions from being a semiconductor to a conductor as the iron content increases.
This is an important property for many industrial applications, such as electronics and optics.
As such, sphalerite is often used in these industries due to its ability to conduct electricity and light efficiently.
The combination of its physical properties make sphalerite crystals an ideal material for many different uses.
Optical properties of sphalerite crystals are determined by its composition and structure.
Pure zinc sulfide is a wide-bandgap semiconductor, with a bandgap of about 3.54 electron volts,
which makes the pure material transparent in the visible spectrum. Increasing iron content will make the material opaque,
while various impurities can give the crystal a variety of colors. In thin section,
sphalerite exhibits very high positive birefringence, with the refractive index ranging from 2.37
when it is pure ZnS to 2.50 when there is 40% iron content. Sphalerite is isotropic under cross-polarized light,
however it can experience pleochroism depending on the impurities present in it.
Additionally, sphalerite may fluoresce under ultraviolet light due to certain impurities present in it.
The optical properties of sphalerite are important for its use as a gemstone and for industrial applications such as
optical lenses and filters. Its transparency in the visible spectrum makes it an ideal material for these purposes,
while its ability to fluoresce under UV light can be used to detect certain types of impurities or defects in materials or components made
Gemmy, colorless to pale green sphalerite crystals from Franklin, New Jersey is a variety of the mineral known as cleiophane.
This type of sphalerite is highly fluorescent under longwave ultraviolet light and is composed of almost pure zinc sulfide (ZnS).
It contains less than 0.1% iron in its crystal structure, making it one of the rarest varieties of sphalerite.
This variety of sphalerite crystals was first discovered in Franklin Furnace,
New Jersey and has since become a popular collector’s item due to its unique properties.
The fluorescent orange and/or blue colors that appear when exposed to
UV light make it an attractive gemstone for jewelry or decorative pieces.
Cleiophane can also be used in industrial applications such as optical lenses and
semiconductor materials due to its high refractive index and low absorption rate.
Sphalerite is a mineral composed of zinc sulfide, and is the primary ore of zinc.
It has a hardness of 3.5-4 on the Mohs scale and can be found in many different colors, including yellow, red, brown, black and green.
It often contains iron and can have a metallic luster or be dull.
Sphalerite crystals are found in many places around the world, including Europe, North America and Australia.
Sphalerite crystals are also highly sought after by collectors for its beauty and rarity.
It is often cut into cabochons or faceted stones to enhance its color and clarity.
The most valuable specimens are those with bright colors that show off its unique sparkle.
Some rare varieties of sphalerite contain traces of cobalt which gives it an intense blue color known as “cobaltian” sphalerite.
This variety is especially prized by collectors due to its rarity and beauty.
What is the meaning of Sphalerite?
Sphalerite crystals are a mineral that has been known since antiquity, but was not officially named until 1847.
Ernst Friedrich Glocker gave it the name Sphalerite, which comes from the Greek word “sphaleros” meaning treacherous or deceiving.
This name reflects the difficulty of identifying Sphalerite due to its ability to combine with many different minerals and
appear differently in each specimen.
The Iron content of Sphalerite can also vary greatly, ranging from nearly clear to totally black.
Few other minerals display such a wide range of transparency as Sphalerite does.
The deceptive nature of this mineral makes it an interesting choice for those looking for something unique and mysterious.
It is often used in jewelry and art pieces because of its beautiful color variations and
its ability to reflect light in different ways depending on how it is cut or polished.
Its versatility makes it a popular choice among collectors and those who appreciate natural beauty.
