Citrine is a gemstone of the quartz family, yellow, whose name comes from the Latin word "citrus", lemon. Its color can change from pale yellow to orange tones. This gem has a hardness of seven on the Mohs scale.
The process of formation of the citrine quartz occurs when the violet of the amethyst is so pale that loses its value as a gem. Because of this effect, the use of citrine has become more common. The countries that exploit this procedure to obtain the citrine stone are Uruguay and Brazil.
Natural citrine is hard to find, so to get a similar stone the amethyst is heated. The violet amethyst is considerably more common.
However, we have a wide selection of citrine within the citrine geodes category.
