Citrine occurs naturally in Scotland and in the Ural Mountains of Russia. Much citrine available today is actually smoky quartz or amethyst that has been heat-treated to achieve its characteristic color. Deep red garnet is derived from a number of minerals, including pyrope and almandine. Popularized in Bohemia in the Czech Republic, garnet has been used in decoration and jewelry across Europe for many years. Its color is generally a dark burgundy, sometimes with a hint of orange, pink, or purple.
