Topaz
is a stone of strength.
Color: Pure topaz is colorless, but
it also occurs in a broad range of colors: yellow, blue, pink,
peach, gold, green, red, and brown.
Some natural yellow stones are heated to become permanently pink
(pinked topaz).
Description: Topaz is an
aluminum fluorite silicate containing fluorine and has a chemical
formula of Al2F2SiO4. It is one of the few gem minerals which,
under suitable conditions, grow into enormous crystals. Topaz
typically occurs in cavities in rhyolites and granite, in pegmatite
dikes, and in high-temperature veins with cassiterite and tourmaline.
The stone is transparent with a vitreous luster. A light yellow,
brown and pink variety of topaz are valued as a gemstone. The
pure crystals of topaz used a great deal in jewelry.
The name's origin: The
name topaz is derived from the Indian Sanskrit word tapas, meaning
fire. According to another theory topaz derives its name from
the Island of Topazos, in the Red Sea, where the Romans obtained
a stone which they called by this name, but which was the modern
chrysolite or Topaz.
Birthstone: Topaz along
with citrine are birthstones of Scorpius (Scorpion): Oct. 24 -
Nov. 21.
Wedding anniversary: Topaz
is the anniversary gemstone for the 4th and 19th year of marriage.
Imperial topaz is the anniversary gemstone for the 23rd year of
marriage.
Varieties: Nothing compares
to the sparkling brilliance of Blue Topaz. Orange-red Imperial
Topaz is rare.
Care and treatment: As
topaz has a hardness of 8, keep your gems in separate boxes to
protect other jewelry from scratches. Also avoid large temperature
changes. Topaz often becomes paler if kept out in the sun. Do
not clean topaz in a home ultrasonic cleaner. The best way to
clean topaz is warm soapy water.
From the stone history:
It is believed that the topaz of modern mineralogists was unknown
to the ancients and that the stone called topazos was the mineral
chrysolite or Topaz.
In ancient times, a figure of a falcon carved on a Topaz was thought
to help earn the goodwill of kings, princes and magnates. Topaz
is Stone of Strength noted by Greeks. During medieval days it
was thought to heal physical and mental disorders as well as prevent
death.
In 1750 a Parisian jeweler discovered that the yellow Brazilian
topaz becomes pink on exposure to a moderate heat, and this treatment
has since been extensively applied, so that nearly all the pink
topaz occurring in jewelry has been heat-treated. Such "burnt
topaz" is often known as Brazilian ruby, as is the very rare,
natural red topaz.
Shopping guide: Topaz looks
beautiful in rings, bracelets, necklaces, and pendants. Blue Topaz
is available in a variety of shades, sizes and shapes. Red and
intense pink are the most rare and most desirable colors for topaz.
Pure topaz when brilliant-cut sometimes is mistaken for diamond.
Healing ability: Topaz
stimulates an endocrine system. It assists in general tissue regeneration.
Topaz is valuable in the treatment of hemorrhages. It also increases
poor appetite and helps fighting blood disorders.
Mystical power: Topaz balances
emotions and calms passions. It releases tension and gives feelings
of joy. Topaz is known as spiritual rejuvenation gemstone.

and in the United States (in Maine, New Hampshire, California,
Colorado, and Utah). In the United States the best topaz has been
worked near Pikes Peak, Colorado, and in San Diego county, California.
The largest known deposits are located in Minas Gerais in Brazil.
The finest British topaz is found in the Cairngorm Mountains in
the Central Highlands, especially at Ben a Buird, Scotland. The
famous topaz rock of the Schneckenstein, in Germany, yields pale
yellow crystals.
Fine topaz occurs at several localities in the Urals and in Siberia,
Russia, and beautiful crystals come from Takayama and Tanokamiyama
in Japan.
Pakistan Deposits: Topaz
is a popular and durable gem. In Pakistan, topaz occurs as euhedral
crystals in pegmatites in Gilgit and Skardu Districts. Topaz crystals
may be found in yellowish brown, golden color, honey-yellow, and
champagne. Deeper sherry-colored topaz crystals are very popular.
Pink topaz is another variety found
in Katlang, Mardan District, Northern Pakistan. The Katlang topaz
is transparent to sub-transparent, colorless, purple or pink and
good crystals are free from impurities. The orange rose or cyclamen
color is unique in the world. The largest crystal recovered so
far is over 7.5 cm in length with deep pink color. The well-formed
crystals have the usual faces of topaz. The topaz occurs in calcite
and quartz vein within limestone.
