VINTAGE ESTATE 10K GOLD ART DECO RING GENUINE CITRINE GEMSTONE C 1920 faceted. About Citrine - History and Introduction. Citrine is one of the most popular gemstones available today. It belongs to the very large family of quartz (SiO2) gemstones. More specifically, it is the yellow to golden-orange variety of gemstone-quality macrocrystalline quartz (silicon dioxide). The name'citrine' was derived from'citron', a French word meaning'lemon', although its color tends to be more golden rather than lemon-yellow. Natural citrine is actually quite rare and because it is more valuable than most other varieties of quartz, much of the citrine today is actually heat-treated to obtain its attractive golden color. Almost all heated citrine will exhibit reddish tints. Citrine is very closely related to violet-purple amethyst, another variety of macrocrystalline quartz.
The only difference between citrine and amethyst is the oxidation level of iron ions (Fe3) present in colorless quartz crystal. When quartz is heated, iron impurities are reduced, resulting in less violet-purple color and more golden to orange colors.
Ametrine is the natural bicolor combination of both golden citrine and violet amethyst in a single specimen. The item "VINTAGE ESTATE 10K GOLD ART DECO RING GENUINE CITRINE GEMSTONE C 1920 faceted" is in sale since Monday, January 22, 2018.
