This article will systematically examine the history and lore of citrine, its geological sources, its defining gemological characteristics, the metaphysical beliefs attributed to it, and practical advice for its care and maintenance.
History and Lore
The history of citrine is as vibrant as its color, tracing back to ancient civilizations that revered its golden hues. The gemstone's name is derived from the French word citron, meaning lemon, a direct reference to its primary color range. This etymological root highlights the long-standing association between the gem and its citrus-like appearance.
Historical records indicate that citrine was in use as early as 300 B.C. by the ancient Greeks, who valued its luminous energy and wore it as jewelry. The Romans also held the stone in high esteem, associating it with the sun god Apollo. Both cultures believed that citrine could bring prosperity, joy, and abundance to the wearer, attributing to it a powerful connection to solar energy and positive outcomes.
The gemstone's appeal extended into the 19th century, where it experienced a significant resurgence in popularity during the Art Deco movement. Its warm, sunny tones perfectly complemented the geometric designs and bold colors characteristic of the era, making it a favored material for jewelry artisans of the time. This period cemented citrine's status as a fashionable and desirable gemstone, a role it continues to fulfill in contemporary jewelry design.
In 1952, the Jewelers of America officially recognized citrine as one of the birthstones for November, placing it alongside topaz. This formal designation significantly bolstered its popularity, integrating it into the modern tradition of birthstone jewelry. The historical journey of citrine—from an ancient talisman to a modern birthstone—illustrates its consistent cultural and aesthetic value across millennia.
Geological Formation and Sources
Citrine is a variety of quartz, one of the most abundant minerals in the Earth's crust. Its chemical composition is silicon dioxide (SiO₂). While quartz is common, natural citrine is relatively uncommon. Most citrine available in the commercial market today is the result of heat treatment applied to amethyst, another variety of quartz. This thermal treatment process alters the crystal lattice and the oxidation state of iron impurities within the amethyst, transforming its purple color to various shades of yellow, orange, or brown.
The sources of citrine are diverse, with Brazil being a prominent location for mining. The country is known for producing impressive large citrine geodes, which are often showcased at major gem and mineral shows. These geodes are found in Brazilian basalt fields and can be quite substantial, sometimes standing several feet tall as crystal towers. When first discovered, these geodes are not filled with the familiar orange to orangy-brown citrine; they typically contain clear or smoky quartz crystals that are later heat-treated to achieve the desired citrine color.
Other sources for citrine, though less frequently mentioned in the context of large-scale production, include locations such as the Madeira Islands. The name "Madeira citrine" is used for gems with rare reddish orange and reddish brown colors, named after the wines produced in this autonomous region of Portugal. This nomenclature indicates that specific color varieties of citrine have been historically recognized and named based on their resemblance to other naturally occurring hues.
Gemological Properties
Understanding the gemological properties of citrine is essential for identification, valuation, and proper care. As a member of the quartz family, citrine shares many characteristics with its relatives but possesses distinct features that define its identity.
Color and Clarity
Citrine's color is its most defining attribute. The color range is broad, encompassing yellow, orangey-yellow, yellowish orange, and brownish orange. The name "citrine" is applied to any transparent quartz within this color spectrum, regardless of saturation. Stones with faint color are abundant and typically inexpensive, while those with a rich, uniform color are rare, valuable, and highly sought after by buyers. A specific and rare color variety is Madeira citrine, which exhibits reddish orange to reddish brown hues.
In terms of clarity, citrine is generally a transparent gemstone. High clarity is a common feature, contributing to its appeal and making it suitable for various jewelry settings where transparency and brilliance are desired.
Hardness and Durability
Citrine has a Mohs hardness of 7. This level of hardness makes it a durable gemstone suitable for everyday jewelry, such as rings, earrings, and pendants. However, its durability should be considered in context. While citrine has a hardness of 7, topaz, the other November birthstone, has a hardness of 8. Despite topaz's higher hardness, it is a brittle mineral that is prone to cleavage (a tendency to break along flat planes), which can make it less durable in certain settings. Citrine, with its good hardness and lack of pronounced cleavage, offers a practical and resilient alternative for jewelry wear.
Cut and Carat Weight
Citrine is cut into a wide variety of shapes and styles to maximize its color and brilliance. Its transparency allows for faceted cuts that enhance its light performance. As a relatively abundant material (especially in its treated form), citrine is available in a range of sizes, making it accessible for both small and large jewelry pieces. Large, well-formed citrine crystals are also valued by collectors.

Symbolism and Metaphysical Beliefs
Citrine is rich in symbolism and is often associated with a range of positive attributes and metaphysical beliefs. These associations have evolved over centuries, from ancient sun worship to modern holistic practices.
Historically, citrine was linked to the sun and solar deities like Apollo, leading to beliefs in its ability to bring warmth, vitality, and joy. It was thought to dispel negative energy and promote positive emotions, making it a popular talisman for healing and protection in ancient rituals.
In modern times, citrine has acquired several nicknames that reflect its symbolic meanings. It is frequently called the "merchant's stone" or the "stone of success." This association stems from the belief that citrine attracts wealth, prosperity, and good fortune. Many business owners keep citrine crystals in their cash registers or offices, hoping to harness its purported energy to enhance business success and financial stability.
Beyond commerce, citrine is also linked to personal attributes such as achievement, self-esteem, and self-perception. It is believed to energize the wearer, fostering a sense of confidence and clarity. In various metaphysical systems, citrine is associated with the solar plexus and sacral chakras, which are related to personal power, creativity, and emotional balance. It is also connected to the planets Sun and Jupiter, and the element of Fire, further emphasizing its qualities of energy, expansion, and warmth.
While these beliefs are popular in crystal healing and New Age practices, it is important to note that they are considered metaphysical and are not supported by scientific evidence. However, they contribute significantly to the gemstone's cultural allure and its popularity among those who value its perceived energetic properties.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of citrine jewelry. Given its gemological properties, citrine is relatively easy to care for, but certain precautions should be observed.
With a Mohs hardness of 7, citrine is resistant to scratching from most common materials. However, it can be scratched by harder substances like corundum (sapphire and ruby) or diamond. Therefore, it is advisable to store citrine jewelry separately from other pieces to prevent abrasive contact. Using a soft cloth or individual jewelry boxes is recommended.
For cleaning, citrine can be safely washed with warm, soapy water and a soft brush. Ultrasonic cleaners are generally safe for untreated citrine, but caution is advised for stones that have undergone fracture filling or other complex treatments, which are not typically mentioned in the context of standard citrine. Steam cleaning is not recommended, as sudden temperature changes can potentially cause damage, especially if the stone has internal inclusions.
Regular cleaning and proper storage will help preserve the gemstone’s luster and color, ensuring that it continues to be a cherished piece of jewelry for generations. Given its durability and affordability, citrine is an excellent choice for everyday wear, but like all fine jewelry, it benefits from mindful handling and maintenance.
