SCIENTIFIC INFORMATION: Grossular Garnets are from a group of very
closely related calcium silicates. The Chemistry for the Grossular
variety is Ca3Al2Si3O12. These Garnets range in color from yellow, pink
and brown through white and colorless. The hardness ranges between 6-1/2
ENVIRONMENT: Grossular occurs with wollastonite, calcite, and vesuviani-
te in hornfels of contact metamorphic rocks.
OCCURENCE: Being the commonest of all garnets, it is found in a variety
of locations. Fine colorless crystals up to 1/2″ across occur in
Gatineau and Magantic Cos., Quebec, fine lusterous pale brown crystals
up to 3″ across were found near Minot, Androscoggin Co., Main, and
beautiful white and pick crystals up to 4″ across have been found near
Xalostoc, Morelos, Mexico.
GEMSTONE INFORMATION: Grossular also has the typical crystal form of
garnets, occuring in isolated crystals which are often complete, in the
shape of a rhombic dodecahedron, sometimes combined with a trapezo-
hedron. They vary from transparent to semiopaque. The typical color is
light (gooseberry) yellowish green; but they can be a strong to bluish
green, honey yellow or pinkish yellow, or even colorless. When transpar-
ent, the crystals have good luster. Like other garnets, they have no
cleavage. The greenish to yellowish varieties are used as gems.
Grossular is not a rare mineral. The types used as gems mainly come from
the gem gravels of Sri Lanka (honey yellow variety); the the United
States, Canada, Mexico, Madagascar, Kenya. The green variety of
grossular garnet, discovered a few decades ago and found mainly in
Kenya, near the Tsavo National Park, is also known as Tsavorite (or
Tsavolite) It is a light, verdant, or dark green, similar to the color
of the better green tourmalines and sometimes, it is said, even
comparable to African emerald. It has good luster. These gems, which are
usually given a round or pear-shaped mixed cut, or occasionally a
brilliant cut, are generally small, rarely exceeding one carat and never
more than a few carats.
NAME: Grossular is from the New Latin [grosssularia,] “gooseberry,”
because some Grossular crystals are pale green like the fruit.
LEGEND and LORE: I do not find anything referring specifically to yellow
or green garnets in my sources.
MAGICAL PROPERTIES: While deep red garnets focus on “Will” and orange–
red garnets focus on “Desire”, yellow garnets are focused on Personal
Power and Personality. In addition they are (because of their color)
associated with athletic prowess and Oriental philosophies.
HEALING: Being linked to the Solar Plexus Chakra, yellow garnets are
energizing. They can be used for the digestive organs, the diaphram (and
the breath) and eyesight. Green garnets center their healing on the
NOTES: Garnets are used in industry as an abrasive.
