Mint Grossular Garnet
Unique source in East Africa
Usually found growing in pockets in the Tanzanite mines in Merelani
Mint Grossular Garnets are bright pastel green Garnets that are found growing in pockets in the same mines as Tanzanite.
This is in Merelani, Tanzania by the foothills of Mt. Kilimanjaro, which is Africa’s highest mountain at 19,341ft above sea level.
They are sometimes known as ‘Merelani Mint Grossulars’ or Merelani Mint Garnets’ and are rare in sizes above 3cts.
They are the same species of Grossular Garnet as their better-known cousin Tsavorite, with the trace elements vanadium and chromium giving them their green color. These gems actually turn pink under the Chelsea filter!
Garnets are part of a large family of silicate minerals that have similar physical properties but vary in chemical composition.
Grossular Garnets have one of the widest color ranges of any species of Garnet, from near-colorless to yellows, oranges, greens and browns.
Garnet is the birthstone for January, celebrates the 2nd Anniversary and comes in almost all colors of the spectrum including the rare color-change material.
Mint Grossular Garnets are a nice green option for January birthdays!
