History and Lore
Topaz has a rich and storied history that dates back thousands of years. The gemstone has been found in archaeological sites across the world, including ancient Egypt, Greece, and India. In ancient Egypt, topaz was believed to be a gift from the sun god, Ra, and was often used in religious ceremonies and amulets. The Greeks associated topaz with the sun and believed it had the power to improve eyesight and bring wisdom to the wearer.
One of the earliest recorded references to topaz is in the writings of Theophrastus, a Greek philosopher and naturalist, who described the gemstone in the 4th century BCE. During the Middle Ages, topaz was believed to have healing properties and was used to treat various ailments, including digestive issues and mental disorders. Alchemists of the time also attributed mystical properties to topaz, believing it could promote strength and courage.
Topaz also has a place in European history. In medieval Europe, it was often used in religious artifacts and royal regalia. The gemstone was a symbol of strength and protection, and it was believed that it could ward off evil spirits and provide a safe passage through life.
In the 18th and 19th centuries, topaz gained popularity in the West, particularly in the United States and Europe. It was often used in Victorian-era jewelry and was a favorite among the upper classes. The gemstone’s affordability and availability made it a popular choice for everyday wear, and it was often used in brooches, rings, and pendants.
The modern tradition of birthstones, which assigns a specific gemstone to each month of the year, dates back to the 13th century. Topaz was designated as the November birthstone during the 20th century, and it has since become an important symbol of identity and celebration. Today, topaz is a popular choice for engagement rings, anniversary gifts, and personal adornment.
Geological Formation and Sources
Topaz is a silicate mineral composed of aluminum and fluorine, with a chemical formula of Al₂SiO₄(F,OH)₂. It forms in igneous rocks, particularly in rhyolite and granite, as well as in pegmatites and cavities in volcanic rocks. The gemstone is also found in sedimentary deposits where it has been eroded from its original source and transported by water.
Topaz is known for its hardness, which is 8 on the Mohs scale, making it one of the hardest naturally occurring gemstones. It has a refractive index of 1.61–1.63, which contributes to its brilliance and fire. Topaz is also known for its excellent cleavage, which means that it can split along specific planes under stress. This property requires careful handling during cutting and setting to avoid damage to the gemstone.
Topaz is found in a variety of colors, including yellow, orange, brown, blue, pink, and colorless. The most common and highly valued color is golden yellow, which is often referred to as "golden topaz." Blue topaz, which is created through irradiation of colorless topaz, is also popular in the jewelry market. Other colors, such as pink and red, are rare and highly prized.
Topaz is mined in various parts of the world, including Brazil, Mexico, Russia, Nigeria, and the United States. Brazil is the largest producer of topaz, particularly the golden and yellow varieties. Mexican topaz is known for its high quality and vibrant color, while Russian topaz is often found in the Ural Mountains. In the United States, topaz is mined in Utah, where it is the state gemstone.
The availability of topaz in different colors and qualities makes it a versatile gemstone for jewelry design. Its durability and affordability have made it a favorite among jewelers and consumers alike.

Topaz is a doubly refractive gemstone, meaning that it splits light into two rays as it passes through the crystal. This property contributes to its brilliance and fire. It is also known for its excellent thermal stability, which makes it suitable for use in jewelry that is exposed to heat, such as in settings with gold or silver.
The gemstone's hardness of 8 on the Mohs scale means that it is relatively resistant to scratches and abrasions. However, due to its perfect cleavage, topaz can be damaged if struck in the wrong direction. This makes it important for jewelers to take care when cutting and setting topaz to avoid accidental damage.
Topaz is also known for its low porosity and minimal inclusions, which means that it is often eye-clean and requires little enhancement. Unlike many other gemstones, topaz does not typically undergo treatments such as heat or irradiation to enhance its color, although blue topaz is created through irradiation of colorless topaz.
The gemstone's availability in a variety of colors and qualities makes it a versatile gemstone for jewelry design. Whether in a classic yellow hue or a vibrant blue, topaz offers a range of options for jewelers and consumers.
