Citrine is a variety of quartz with colors that range from yellow to yellow-green. It is still unclear what causes the color. In some citrines, it is believed that iron or aluminum-based and irradiation-induced color centers similar to those in smoky quartz may be responsible for the color. This is supported by the fact that some citrines tend to have smoky shades or transition to smoky colors. Most natural citrines are a pale yellow.
It is rare to find natural citrine. Heated amethyst, usually of lesser quality, is sold as citrine. Some smoky quartz can have its color altered to yellow when heated, as well. Inclusions of yellow iron oxides (“limonite”) may mimic citrine, as can thin layers of iron oxides on colorless quartz. Most of the “citrine” found on the market today is in fact amethyst or smoky quartz found in Brazil or Uruguay and have a deep orange – reddish tint, which is not found in natural citrine. However, albeit rare, natural citrine was found in Ural Mountains, Russia, as well as Kazakhstan or Madagascar.
Citrine is found mostly in quartz veins. In most cases, the size of natural Citrine is a few carats. A lot of times, this stone is confused with topaz. It differs significantly from topaz. In Citrine, iron deposits are found within the crystalline structure. Citrine shares the same composition with Amethyst, only its oxidizing state differs.
Citrine can be be prismatic, striated, or massive granular, and it is often twinned. Citrine name is derived from citrin, which means yellow in French. It has basically the same properies as Amethyst, and they share their chemical composition with the larger and common quartz family.
Citrine was often referred to in old times as “The Merchant’s Stone.” People believed it would bring wealth and prosperity to a person. In ancient China it was believed that citrine was the “stone of success” and that only generous people should be given it.
