Tourmaline
Tourmaline's name comes from the Sinhalese tura mali, which means "mixed
stone." Available in a rainbow of
colours and colour combinations,
Tourmaline lives up to its name.
Legend
says Tourmaline inspires artistic
expression and enhances your intuition.
Certainly this gem's varied palette
inspires designers to create jewelry to
suit every mood.
Tourmaline offers an enticing rainbow of
options for your jewelry wardrobe. Cranberry red, hot magenta, bubblegum
pink, peach and orange, canary yellow,
mint, grass and forest green, ocean
blue, violet, and even bicolour pink and
green stones: Tourmaline is all these
and more.
The most valuable colours of Tourmaline
are the rare electric blues and greens
discovered in Paraiba, Brazil in 1989.
Such gems can command tens of thousands
of dollars per carat. Blue
indicolite, red rubellite, and green
chrome Tourmaline are also coveted and
fine-quality material is hard to find
and highly valued.
Pink and mint green
Tourmaline, however,
is widely available and more affordable,
with prices in the hundreds of dollars
per carat. The Empress Dowager Tz'u Hsi, the last empress of China,
loved pink Tourmaline above all other
gemstones.
She imported tons of
Tourmaline from Southern California in
the early twentieth century, creating a
gem rush in San Diego during the period.
In addition to unusually varied beauty,
Tourmaline has unusual electrical
properties. Crystals acquire a
polarized electrical charge when heated
or compressed. This property has
also made Tourmaline the latest miracle
ingredient in moisturizers:
manufacturers claim the gem helps pull
pollutants from your skin.
Almost every colour of Tourmaline can be
found in Brazil, especially in Minas Gerais and Bahia. In addition to
Brazil, Tourmaline is also mined in
Tanzania, Kenya, Nigeria, Madagascar,
Mozambique, Namibia, Afghanistan, Sri
Lanka, and California and Maine in the
United States.
Because they grow in thin pencil-like
crystals, Tourmalines are most often cut
into long rectangular shapes known as
emerald cuts.
The pink
colours of Tourmaline can be
enhanced with exposure to radiation and
some blues and greens improve with heat
but the results are stable and
undetectable, so no one knows how common
these practices are. Red
Tourmaline,
which is often very included, can
sometimes have surface-reaching fissures
filled with resin to make them less
visible.
Tourmaline is durable and suitable for
everyday wear. Clean with mild dish
soap: use a toothbrush to scrub behind
the stone where dust can collect.
