- Garnet is a group of
minerals that have been used since the Bronze Age as gemstones and
abrasives. Garnets are most often seen in red, but are available in a
wide variety of colors spanning the entire spectrum. The name "garnet"
comes from the Latin granatus ("grain"), possibly a reference to the
Punica granatum ("pomegranate"), a plant with red seeds similar in
shape, size, and color to some garnet crystals.
- The garnet varieties
are Almandine, Pyrope, Spessartine, Andradite, Grossular and
Uvarovite.The following properties are attributed to some of the
specific garnet varieties: Almandine is said to be particularly usefull
for strengthening the heart, to inspire love and to perceive truth.
Andradite is said to give vitality and to help prevent fears,
insecurity, and feelings of loneliness. Pyrope is said to enhance
understanding and wisdom. Rhodolite is said to facilitate meditation and
enhance intuition, and to inspire love. Tsavorite is said to facilitate
meditation, and to enhance spiritual awareness and telepathic abilities.
- Mantle-derived
garnet peridotites are a minor component in many very high-pressure
metamorphic terranes that formed during continental subduction and
collision. Some of these mantle rocks contain trace amounts of zircon
and micrometer-sized inclusions.
- Garnets are also
useful in defining metamorphic facies of rocks. For instance, eclogite
can be defined as a rock of basalt composition, but mainly consisting of
garnet and omphacite.
- Garnet is mined as a
gemstone and an industrial material, but it is valued primarily for its
many industrial applications. The United States developed substantial
garnet abrasive technology and applications earlier than other countries
mainly because of the large deposits of high-quality abrasive garnet in
New York.
- The United States
was the world’s largest consumer of industrial garnet, accounting for
20% to 25% of global consumption. In 2000, the U.S. apparent consumption
of industrial garnet was estimated to be 25,400 t, which was a 45%
decrease from the 1999 apparent consumption. This apparent consumption
decrease was due to a 75% increase in U.S. producer stocks. Most of
these stocks were concentrated in two of the U.S. industry’s five
producers.
- The wide price range
of industrial garnet was based on the type, source, quantity purchased,
quality, and application. In 2000, average values for crude concentrates
ranged from about $53 to $254 per ton, and average values for refined
garnet sold during the year ranged from $61 to $265 per ton. However,
spot prices reached as high as $441 per ton. Quantities sold by U.S.
producers increased by approximately 17%, and the value of sales
increased by about 21% during 2000.
- Garnet for
industrial use was mined in 2006 by four firms, one in Idaho, one in
Montana, and two in New York. The estimated value of crude garnet
production was about $3.38 million, while refined material sold or used
had an estimated value of $6.20 million. Major end uses for garnet were
abrasive blasting media, 35%; waterjet cutting, 30%; water filtration,
15%; abrasive powders, 10%; and other end uses, 10%.
- During 2006, U.S.
garnet consumption increased 8%, while domestic production of crude
garnet concentrates decreased by 12% compared with the production of
2005. In 2006, imports were estimated to have increased 25% compared
with 2005, and exports were estimated to have decreased slightly from
those of 2005. The 2006 estimated domestic sales of garnet remained at
about the same level as sales of 2005. In 2006, the United States
was a net importer. Garnet imports have displaced U.S. production in the
domestic market, with Australia, Canada, China, and India being major
garnet suppliers.
