Natural Citrine Point Calcite Malachite is also found asFrom the Latin word "citrus citron tree", Citrine is a variety of Quartz and a semiprecious gemstone known for its yellow to golden brown color. It is composed of silica (SiO2) and iron oxide inclusions that cause the yellow hue of the crystal.
