Citrine is defined as “a pale yellow quartz resembling topaz.” Amethyst and citrine are both varieties of quartz, one of the most common minerals in the Earth’s crust. The natural abundance and infinite variety of quartz have made it the most widely used of all gem minerals.
Citrine is rare in nature. In the days before modern gemology, its tawny color caused it to be confused with topaz. Today, its attractive color, plus the durability and affordability it shares with most other quartzes, makes it the top-selling yellow-to-orange gem. In the contemporary market, citrine’s most popular shade is an earthy, deep, brownish or reddish orange.
