Availability:
Natural Citrine is comparatively rare, whereas heat-treated Citrine is relatively
plentiful and available in a wide variety of shapes and sizes.
Sources:
Today the prime supplier of Citrine is Brazil, although Citrine can also be found
in Bolivia, France, Madagascar, Russia, Scotland, Spain, United States (North Carolina,
Colorado, Georgia, Nevada, California), Uruguay, and Zambia.
Evaluation:
Citrine is rated 7 on the Moh's Scale of Hardness, making it a durable gemstone
suitable for everyday wear. Whilst essentially sharing the same chemical make-up,
it is less expensive than its close relative, Amethyst. Thanks to its durability
and availability, Citrine is one of the most affordable gemstones available, presenting
excellent value for money. This value is further enhanced by the fact that owing
to strong availability, per carat prices do not exponentially increase with size.
Citrine is available in a variety of colors of yellow, yellow-brown, orange, red-orange,
dark orange-brown, and reddish-brown. Though the darker, orange colors of Citrine
have historically been considered more valuable, many people are today beginning
to prefer the bright, juicy, lemony shades that Citrine offers.
It should be noted that natural Citrine is pale yellow to pale orange in color,
whereas heat-treated Citrine is orange-brown to reddish-brown in color. Citrine
in the “brown” colors is almost always heat-treated Amethyst.
Common Cuts:
Due to the ready availability of large Citrine gemstone examples, Citrine is often
custom cut into intricate shapes. It is also commonly cut into Cabochons, Emerald,
Oval, Pear, Round and Square shapes / cuts. Citrine is also often sculpted into
ornaments and cut into beads.
Routine Enhancements:
Citrine gemstones are usually heat-treated in order to produce the best coloration.
This method of treatment is considered a permanent treatment and the color should
not fade over time. When purchasing any Citrine presume that the stone in question
has been heat-treated unless otherwise specified.
Care & Cleaning:
Use warm,
soapy water and a soft brush to clean Citrine. Ultrasonic cleaners are
generally safe. Never use chemicals such as hydrofluoric acid or ammonium fluoride
to clean Citrine because it can erode the stone. Much like relative the Amethyst,
Citrine
should be kept away
from prolonged exposure to extremes of heat and light
as this can cause permanent color change. Citrine should be kept in a fabric lined
box away from other jewelry items in order to avoid scratching.
