Although, often cut as a gemstone, citrine is actually somewhat rare in nature. 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 with colors 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. Interestingly, a popular gemstone on the market is a mixture of half amethyst and half citrine and is given the name ametrine. Unfortunately, citrine is often confused with the more expensive orange-yellow topaz and is at times sold as topaz by unscrupulous dealers. This practice has soured many potential citrine fanciers who see citrine as a fake topaz and not as a legitimate gemstone.

Quartz is the most abundant mineral in the earth’s continental crust. In jewelry, the quartz group is notable for the large variety of gemstones that can be offered at affordable prices. The quartz gems comprise several different groups including both crystalline varieties like citrine, amethyst, and rock crystal as well as the crypto-crystalline varieties like chalcedony, jasper, chrysoprase, and a host of other agates. The name quartz derives from the Greek word 'krustallos' meaning ice, because the Greeks believed that quartz was ice that never melted because it was formed by the gods.

Quartz is formed in many different ways and occurs in many igneous and metamorphic rocks, particularly in granite and gneiss. It is also a common gauge mineral in mineral veins and most crystals are found in this type of occurrence. With a hardness of 7, quartz is tough enough to resist weathering and is commonly found in alluvial sands and gravels. 

Quartz is found throughout the world. The most abundant deposits of amethyst occur in Africa and Brazil. Madagascar, Brazil and Namibia are important sources for rock crystal. Chrysoprase occurs in Africa, Brazil and Australia. Jasper, chalcedony, and other agates are found on every continent.
