CITRINE
: The Yellow variety of
Quartz is known as Citrine Quartz, or
simply Citrine, despite the fact that
generally the colour is nothing like
lemon yellow. It was and still called
Topaz or Topaz Quartz as well, because
of a similarity in colour, much to the
detriment of true Topaz. It has a good
lustre and is generally a clear stone.
Citrine is one of the most affordable
gemstones, thanks to the durability and
availability of this golden quartz.
Named from the French name for lemon,
"Citron," many citrines have a juicy
lemon colour. Although normally good,
its lustre is slightly inferior to that
of Topaz. Its lustre lasts for a very
long time. Colour Zoning, where present

Citrine is the most affordable of all
the earth-toned gemstones, thanks to its
durability and availability. It has
become increasingly popular with
budget-minded women looking to expand
their work and leisure jewelry
wardrobes.
Citrine, a form of quartz, derives its
name from the French word for lemon,
"citron." It is available in a range of
golden hues from lemon to straw to sun
yellow to gold, as well as oranges,
browns, and deep madeira red. It is
generally more inexpensive than amethyst
and is also available in a wide range of
calibrated sizes and shapes, including
very large sizes.
Citrine's lively colors can brighten
almost any jewelry style, and it blends
especially well with yellow gold. Its
low cost makes it an ideal stone for
popular free-form fancy cuts for
one-of-a-kind and customized pieces. And
good cut is as important in determining
citrine's quality as it is for more
expensive yellow counterparts, such as
yellow sapphire.
As
with other stones, citrine in very large
sizes (above three carats) in rich, deep
colors has always been rare and
therefore the most valuable form of the
gem. Although this stone's dark orange
and red shades traditionally have been
the most prized, its bright lemony hues
have become very popular in recent years
because they mix better with pastel
colors.
In
ancient times, citrine was carried as a
protection against snake venom and evil
thoughts. It was also thought to give
calmness and mental balance to its
wearer.
Citrine is the birthstone for November,
as well as recommended jewelry gift for
couples celebrating their 13th wedding
anniversary.
Most
citrine is mined in Brazil. Supplies are
most plentiful in the Brazilian state of
Rio Grande do Sul, particularly from the
Serra mine. The Ira' mine also produces
large quantities of the gem.
These
stones generally start life as either
smoky quartz or amethyst geodes. Heat
treatments first turn them clear and
then give them a permanent color ranging
from yellow to brownish red.
Sometimes citrine is referred to as
topaz quartz, which is incorrect. The
name refers to the color, which is
sometimes similar to topaz. But since
topaz is a separate mineral, the name
could be confusing and should not be
used.
Occasionally, Mother Nature combines the
colors of amethyst and citrine into a
single gemstone called Ametrine.
With
a ranking of "7" on the Mohs Scale of
hardness (from 1-10, with "10"
representing a diamond, the hardest
mineral on earth), citrine has excellent
durability and is suitable for everyday
wear. However, since much of the citrine
on the market today has been heat
treated to improve its color, it should
be kept away from prolonged exposure to
strong light or heat.
The
Hindi Name for the Gemstone being "SUNHERA".
Appearance :
The colour varies from pure yellow to
dull yellow, honey, or brownish yellow.
As with Amethyst the colour is often
broken up into patches or bands,

zoning is less obvious. It has a good
lustre and is generally a clear stone.
