Citrine tumbles

Citrine is the name given to the yellowish/orange variety of Quartz that has inclusions of Iron. It can be found crystallized in any form that Quartz is found in and is yellow or orange in color. Most citrines on the market have been heat treated. Specimens of low grade, inexpensive amethyst or smoky quartz are often cooked at high temperatures to produce the more profitable orange yellow citrine. Citrines whose colors have been produced by artificial means tend to have much more of an orange or reddish caste than those found in nature, which are usually a pale yellow. Much of the natural citrine may have started out as amethyst but heat from nearby magmatic bodies may have caused the change to citrine.
