| Size

Like all quartz gems,
amethyst is relatively plentiful and is available
in a wide range of sizes and shapes, including very
large sizes. For extra brilliance, many Iris Amethysts
are polished into Radial CutsTM, which have clever
curved facets that focus light like lenses. |

Available |
|
Ovals, cushions, checkerboards,
round brilliants, trillions, princess cuts, Portuguese
rounds, opposed bars, and a variety of Radial Cuts. |

| Enhancement |
|
Most amethyst is untreated
but some very dark amethyst tones will be heated
at low temperatures to lighten the color slightly.
There is a synthetic amethyst that is manufactured
in Russia, China, and other places. A few suppliers,
like Columbia Gem House and Trigem Designs, will
guarantee the natural origin of their amethyst because
they control the chain of custody from the mine
to the market. Only a few labs, primarily the American
Gem Trade Association's Gemological Testing Center
in New York, can separate synthetic from natural
amethyst, so exercise caution with bargain buys. |

| Lore
& History |
|
Amethyst comes from the
Greek amethystos which means "not drunken." Wine
goblets were carved from this purple gem because
it was considered to prevent drunkenness. (Of course,
the purple color would have also allowed hosts to
water down the wine!) Buddhists believe amethyst
aids meditation, and today it continues to be used
for rosaries in Tibet. Great thinkers like Leonardo
da Vinci believed that amethyst could dissipate
evil thoughts and quicken the intelligence. Amethyst
is the birthstone for February and the zodiac stone
for Pisces. |

| Special
Characteristics |
|
The legend of the origin
of amethyst comes from Greek myth. Dionysus, the
god of intoxication, was angered one day by an insult
from a man and swore revenge on the next mortal
that crossed his path, creating fierce tigers to
carry out his wish. Along came unsuspecting Amethyst,
a beautiful young maiden on her way to pay tribute
to the goddess Diana. Diana turned Amethyst into
a stature of pure crystalline quartz to protect
her from the brutal claws. Dionysus wept tears of
wine in remorse for his cruel act. The god's tears
stained the quartz purple, creating the gem we know
today as amethyst. |
