About Spessartite Garnet - History and Introduction
Spessartite garnet is an orange to red-brown gemstone that belongs to the large and varied garnet species of gems. The garnet group can be classified into two primary classes; pyrospites (aluminum) and ugandites (calcium) garnets. The name, "spessartine" comes from the Bavarian word, "Spessart", meaning "forest", which is a mountain range in Germany where spessartine garnet deposits were found in the 1880s. Spessartite garnet was not often seen in jewelry until deposits were mined in Namibia and Mozambique in the 1990s. Spessartite with intense yellow-orange color are often traded as 'Mandarin garnet'. Mandarin garnet is famed for its fiery color and its wonderful brilliance.
The spessartine garnet species includes a variety of garnet gemstones, including rare color-change garnet and a hybrid garnet known as Malaya garnet (or Malaia). Color-change garnet is extremely rare and is highly prized for its ability to change color when viewed using differing light sources. Color-change garnet is typically a hybrid too, a mix of spessartite and pyrope garnet. Malaya garnet is a rare garnet variety that is gets its name from the Swahili word meaning "outcast" or "prostitute". This is because when malaya garnet was first discovered, it didn't fit into the accepted garnet categories and was therefore cast aside. Malaya garnets are interesting and unique colors, such as pinkish-orange, reddish-orange and yellowish-orange with scintillating flashes of red.
Spessartite garnet can be identified by its orange color. Garnet in general can be distinguished from other gem types by its occurrence in metamorphic rock, its hardness (6.5 - 7.5 on the Mohs scale), color, refractive index and cubic crystal structure. However, the quickest way to identify garnet is with the use of strong neodymium magnets. Garnet is attracted to neodymium magnets because it contains high concentrations of iron and/or manganese. Spessartite garnet can be distinguished from other garnet types by its high range of magnetic susceptibility (SI).

Spessartite Garnet Color
Spessartite garnet can range in color from warm yellow to orange-red. The most desired color for spessartite garnet is a reddish-orange, which is known as "aurora red" or "mandarin spessartite". This is a pure orange without brown tints. Spessartite is ideochromatic, which means its color is owed to an important element in its composition (manganese). It is the manganese which produces its attractive, striking orange color.
Spessartite Garnet Clarity and Luster
Spessartite garnet's high refractive index and vitreous luster means that it has good brilliance. Spessartite garnet is transparent to translucent. "Eye clean" gemstones are quite rare for this variety of garnet, especially 'mandarin garnet' mined from Namibia. Namibian material often contains small fibrous inclusions of tirodite, a mineral which gives this orange garnet a stunning sleepy look.
Spessartite Garnet Cut and Shape
Translucent spessartite garnet is commonly cut en cabochon, while high-quality transparent material is cut in a variety of faceted shapes. Spessarite is often cut with extra faceting techniques to bring out its brilliance. Ovals, cushions, trillion and octagon (emerald-cut) shapes are most common, as these shapes maximize the final weight of the rough stone to be cut. Since garnet lacks pleochroism, proper orientation of the stone is not an issue for gemstone cutters.
Spessartite Garnet Treatment
Like all garnet varieties, spessartite garnet is not known to be treated or enhanced in any way. Spessarite is one of the best gemstone choices available today when it comes to those looking for high quality untreated gemstones for their gemstone jewelry.

Spessartite Garnet: Related or Similar Gemstones Back to Top
As a member of the garnet family, spessartite is related to the other garnets, such as andradoid garnets (melanite, demantoid and topazolite), almandine garnets, pyrope garnets (rhodolite), grossularite garnets (hydrogrossular, hessonite, leuco garnet and tsavorite) and uvarovite. Spessartite garnet can sometimes be confused with hessonite garnet, but due to low levels of iron in hessonite, an N-52 magnet can be used to tell the difference between the two garnet varieties. Hessonite is not attracted to the magnet whereas spessartite is.
Spessartite can sometimes be confused with other gemstones such as andalusite, chrysoberyl, fire opal, sphene and topaz.

Spessartite Garnet Gemstone and Jewelry Design Ideas Back to Top
Spessartite garnet has a good level of brilliance and an attractive vitreous luster, so when set with white or yellow precious metals, the results can be fantastic. Spessartite can be used as a statement gemstone or it can be mixed with other colored gemstones for a cascade of colors such as in Dior's "Dentelle Opale d'Orient" bracelet. Spessartite is often seen mixed with diamonds or other colorless gemstones such as white sapphire or white topaz. Emerald or other green gemstones such as deep forest-green chrome diopside provide a wonderful contrast for spessartite garnet, as seen in Bulgari jewelry designs. Like all garnet varieties, spessartite garnet is perfectly suitable for all types of jewelry; including daily-wear spessartite garnet rings. Garnet gemstones are quite hard and considered to be very durable, especially when compared to many other types of gemstones used in the jewelry available today, such as opal or turquoise for example.
Note: Buy colored gemstones by size and not by carat weight. Colored stones vary in size-to-weight ratio. Some stones are larger and others are smaller than diamonds by weight in comparison.
