This natural spessartine garnet is very lively and glows with only a minimal amount of light, when most other gems are already dim. Its colour is best described as a vivid yellow mixed with a touch of light orange. Square cushion shape and a medium size make this garnet useful for almost any type of jewel. Inclusions in this stone are transparent and hard to see with unaided eye. They do not detract from its beauty and may possibly help to bounce the light inside of the stone, increasing its brilliance.

Spessartine or Spessartite (US) is a manganese-aluminium silicate that belongs to the garnet family.
The prime quality stones show a lively orange colour and it is not uncommon for them to be eye clean. Spessartines are coloured by trace amounts of manganese in their atomic structure. It makes them bright orange and can turn to dark red-orange/brown if iron is also present. Current sources include Namibia, with stones considered the best in terms of colour but rarely clean. Most have tiny fibrous inclusions that give them hazy look. Other notable mining sites are located in Nigeria, Tanzania and Sri Lanka.
At the moment there are no known treatments or synthetic stones on the market. Spessartines are quite durable with a hardness of 7.25 and safe to put into ultrasonic cleaners, as long as there are no liquid inclusions. Same as with other gems we recommend cleaning with a soft brush and drying with a clean cloth.
