Citrine is yellow quartz. German metallurgist Georg Bauer recognized the rare qualities of citrine 450 years ago and named it "citrine," from the French "citron" for lemon and the Latin "citrus."
Citrine is a yellow variety of quartz displaying hues ranging from pale yellow to brown. Natural citrines are rare; most commercial citrines are heat-treated amethysts or smoky quartzes. Citrine is visually similar to yellow topaz, but they differ in hardness. Citrine has ferric or iron impurities and is rarely found naturally.
LOCATION: Rio Grande do Sul, Brazil
We acquire Brazilian Citrine from the Rio Grande do Sul, home to the best quality of citrines in the world. This section borders both Uruguay and Argentina. Currently there are two mines producing citrine, the Serra and Iraâ mines. Each mine yields a minor portion per month and we are fortunate to acquire its supply from the Serra mines.
