From the American Gem Trade Association ...."All About Citrines"
Posted on 06 November 2014
"Shining with a golden glow, people have long treasured citrine as a gift from the sun. Citrine, a variety of transparent quartz, is named after the French citron , or lemon. Its color ranges from a juicy lemon yellow to a bright orangey brown.
In all of its glorious golden and yellow colors, citrine is one of the most affordable of all the earth-toned gemstones, the perfect complement to all the warm tones in your wardrobe. Its sunny shades are also a lovely way to light up black and gray or contrast against blue.
In ancient times, citrine was said to have the power to ward off snake bite. Even more powerfully, the ancients believed citrine also protected against the venom of evil words and thoughts. Citrine is an alternate birthstone for November.
Citrine was particularly popular in the retro jewelry of the 1940s. Its sunny color and dramatic proportions suited the streamlined style and bold gold of the era. It was often set with ruby, peridot, and aquamarine in colorful brooches, necklaces and bracelets. Jewelry designers today also love to set citrine in yellow gold, either alone or in combination with amethyst, blue topaz, or peridot.
Most citrine is mined in Brazil, particularly the state of Rio Grande do Sul. Citrine originate as purple quartz, called amethyst, and, after more years of pressure and heat, the purple fades and a golden yellow takes its place.
Sometimes vitrines are referred to as topaz quartz. Many yellow gems have been called topaz over the years. Since topaz is a separate mineral, the industry has ruled to eliminate this name as confusing.
Citrine is generally more affordable than amethyst. Like all quartz gems, citrine is relatively plentiful and is available in a wide range of sizes and shapes, including very large sizes. Joan Crawford often wore an emerald-cut citrine ring that was more than 100.carats. with a matching cuff bracelet and necklace also set with huge citrines.
Like other quartz gems, citrine is durable and great for everyday wear. Clean with jewelry cleaner recommended by your local jeweler. Avoid exposure to high heat, which may fade its color."
