Citrine is a variety of quartz that is prized for its warm golden hues. Ranging in color from pale yellow to a deep orangey brown, citrine is often referred to as the “sun stone” due to its ability to retain and emanate the energy of sunlight. This sunny appearance has linked citrine to feelings of joy, energy, and prosperity throughout history, making it one of the most popular gemstones.
Unlike many precious gems, citrine is widely available and affordably priced. Its yellowish color is caused by traces of iron impurities present during the stone’s formation. Citrine’s ready availability and iron content distinguish it from the rare golden varieties of beryl and topaz that it can resemble. While some citrine may be marketed under names that aim to link it to these rarer gems, citrine remains a semiprecious quartz valued for its distinctive warm tones.
As the birthstone for November and a stone associated with positive energies, citrine is fashioned into a wide array of jewelry. Its durability and affordable cost also make it ideal for statement pieces. Whether worn as a talisman to spark creativity or set in a ring to celebrate new beginnings, citrine brings a sense of optimism and light to its wearer. For these reasons, citrine continues to shine as a popular gem for jewelry designers and collectors alike.
Physical Properties
Citrine has a hardness of 7 on the Mohs hardness scale, which means it is durable enough for nearly any type of jewelry. It has a trigonal crystal system and a chemical composition consisting of silicon dioxide with iron impurities. The iron content is what produces the colorful yellow, orange, and brown shades seen in citrine gemstones.
The exact hue of citrine can vary based on the precise amount and oxidation state of the iron present. Pale yellow citrine has very little iron, while deep reddish-orange stones have more substantial iron content. Natural citrine with a clear, intense color is rare, so most commercial citrine has been heat-treated to produce a more saturated yellow to brown tone.
In addition to its iron content, citrine can be identified by its conchoidal fracturing pattern, vitreous luster, and transparency. Natural stones will often contain inclusions as well. Citrine sources worldwide, with major deposits located in Brazil, Spain, Russia, and the United States.
Metaphysical Properties
Citrine has long been revered for its sunny appearance and associated positive energies. Ancient civilizations believed it carried the powers of the sun, bringing vitality and strengthening life force. In crystal healing traditions, citrine is said to activate creativity, promote prosperity and abundance, and invoke feelings of joy, comfort, protection, and calmness.
Wearing or carrying citrine is believed to sharpen mental clarity and intellect. Citrine is also thought to encourage sharing of ideas and open communication. Due to its energizing solar associations, citrine makes an ideal crystal for depression, self-doubt, anger, and fear. It brings optimism and acceptance rather than remaining stuck in negative thought patterns.
In crystal grids and Feng Shui, citrine lends its bright, stimulating energy to enhance any space. Simply gazing upon citrine is said to uplift mood and promote positive thinking. This “merchant’s stone” can draw in success, prosperity, and riches when incorporated into spaces where work is conducted.
Geological Information
Natural citrine forms when quartz crystals contain trace amounts of iron during their growth. The iron acts as an impurity that produces the yellow to brown coloration. Most commercial citrine is created by heat treating purple amethyst or brownish smoky quartz to alter the color. Heating removes certain iron compounds and causes the remaining iron to oxidize, resulting in citrine’s characteristic hues.
Geologically, citrine is found in igneous, metamorphic, and sedimentary rocks in many environments worldwide. Major deposits are located in Brazil, Spain, France, Greece, Madagascar, Russia, and the United States. Citrine has been found on all continents except Antarctica.

History and Lore
The name citrine originates from an old French word, “citrin”, meaning lemon-yellow. It first emerged around the mid-16th century and became widely used by the 1800s. However, golden quartz was used decoratively and ornamentally since ancient times. Egyptian artisans crafted jewelry containing citrine over 3,000 years ago.
Ancient Greeks and Romans also used citrine gemstones and crystal goblets, believing they would protect against poison. Citrine was highly desired during the Middle Ages and often set in gold for Medieval jewelry. Scottish weapons featured carved citrine amulets meant to ensure victory in battle and protection against injury.
During the Art Deco era in the early 1900s, citrine saw resurgence in popularity and was featured in prominent jewelry designs. Today, it remains one of the most affordable and frequently purchased gemstones. It serves as an alternative to yellow sapphire, topaz, and amber in less expensive jewelry.
Buying Guide
When shopping for citrine, it is important to understand that completely natural stones are extremely rare. The vast majority of citrine gems and crystals have been treated to enhance their color. Heat-treated material is affordable and displays the bright, saturated hues most consumers desire.
Well-cut citrine sells for approximately $5 to $30 per carat. Pricing depends on the clarity, saturation of color, and cut quality. Larger stones over 5 carats command much higher prices. Like all quartz, citrine is easy to locate inclusion-free, so “eye-clean” gems are abundant.
Citrine works well in any jewelry setting, from antique-inspired to modern minimalist. Protective settings like bezels can help prevent damage from knocks and daily wear. Avoid prolonged sun exposure, as this can cause citrine to fade over time. Occasional cleaning with mild, soapy water is recommended.
Polishing and Cutting
In jewelry manufacturing, most citrine is faceted to maximize its optical properties. Round brilliant, oval, emerald, and cushion cuts showcase citrine’s clarity and dissipate light beautifully. Cabochon cuts display the stone’s color well but do not feature the sparkling facets.
Faceting is done mechanically by securing the rough citrine on a dop stick with wax then placing it on a lapidary machine. The facets are cut and then hand-polished on a spinning wheel. Cabochons are shaped by grinding the back of the stone on a lap wheel until smooth, then highly polishing the domed top by hand.
Other enhancing techniques like fracture filling, oiling, and irradiation may be applied to improve the gem’s durability, color, or transparency. However, heating is the most common citrine treatment and produces the most natural looking results.
Industrial Uses
While citrine’s main use is in jewelry, its durable nature and ability to hold energy also lends itself to industrial applications. Citrine crystals can hold electrical charge, so they are utilized for electrical circuits and optical equipment. The heating power of citrine is harnessed for lasers and radioactive containment.
Hardness and resistance to scratching make citrine useful for watch crystals, optical instruments, and protective windows. Citrine does not fatigue easily and can withstand high pressures and temperatures in these functions. Non-jewelry uses of citrine account for approximately 20% of its consumption worldwide.
Mystical Citrine Legends
Many intriguing myths and legends surround citrine due to its long history and associations with power and healing. It was known as the “Lion Stone” for protecting against evil thoughts and snake venom. Ancient soldiers carried citrine for strength, and tribal kings used it invoke trust in leadership.
Some believed citrine was a gift from the sun god, sent to spread solar blessings onto the earth. There is a myth that citrine can draw wealth and prosperity if placed in the southeast corner of a home or business. Citrine’s warm glow is said to invite happiness and discourage negativity.
Shamans relied on citrine to connect with higher guidance and channel positive energy. Citrine’s capacity to balance emotions was revered by early spiritual leaders. To many, this solar quartz remains synonymous with the life-giving light, vitality, and abundance of the sun.
