Malaia Garnet

Discovered in the mid 1960's in Tanzania's Umba Valley, this red-orange to pink-orange variety of garnet was originally thought to be spessartite garnet. Actually a mixture of pyrope and spessartite, malaia garnets are lively gems that exhibit sparkling red flashes. Once discovered not to be spessartite, it soon became known by the Swahili word malaia, meaning "out of the family." Malaia garnets are available in numerous shades of orange, ranging from soft peach to intense reddish orange.
