Citrine and basic information on this gemstone

This gemstone is the official birthstone for the month of November. It is also the Planetary stone for the Sun Sign of Virgo and the accepted gem for the 13th and 17th wedding anniversary. Citrine is a variety of quartz ranging in colors of yellow, yellow-brown, orange, dark orange-brown, reddish-brown. Crystals can form together with amethyst or smoky quartz to form a bi-colored quartz called ametrine.

CitrineAlmost all citrine that is available on the market today is heat-treated amethyst. Natural citrine is pale yellow to pale orange, much lighter than the heat-treated material which is dark orange-brown to reddish-brown. All of the heat-treated material has a red tint, while natural citrine does not. Some amethyst deposits have been found where the amethyst was changed naturally by high temperatures to brown citrine.

Most citrine comes from Brazil, but almost all of the Brazilian material is heat-treated amethyst. Natural citrine can also be found in the Ural Mountains of Russia, in France, and in Madagascar. The inexpensive low grade amethyst is heated at high temperatures to produce the popular orange, reddish and sherry colored citrine. [intlink id=”2671″ type=”post”]Rubies and Sapphires[/intlink]

Darker colors are considered more valuable, including the medium golden orange and dark sherry-colors.

This gemstone may be mistaken for the more expensive orangish-yellow topaz and, at times, may be sold as topaz by gemstone vendors. Due to this, citrine buyers are sometimes suspicious of any citrine and think it may actually be fake topaz.

It is a 7.0 on the Mohs scale of hardness. [intlink id=”52″ type=”category” target=”_blank”]Gemstones in articles[/intlink]
