What Is Topaz?
Topaz, symbolized by the chemical formula Al2(F1OH)2SiO4, is a rare silicate material. This semi-precious gemstone can vary in color from pale yellow to red and blue and is specifically associated with November as its birthstone.
Topaz crystals form within igneous rocks as magma cools and fluorine, required for topaz formation, is released.
Why Is It Called Topaz?
Several theories exist regarding the origin of the name “Topaz.” Some suggest it comes from the Greek word “Topazion,” derived from the Sanskrit word for fire. Others believe it was named after Topezos, an island in the Red Sea. Another explanation ties it to the Hindu word for heat. In Hinduism, topaz is highly significant, believed to be one of the nine sacred stones and a symbol of the Kalpa Tree.
Where Is Topaz Found?
Topaz is found worldwide, with significant deposits in Brazil, Russia, Pakistan, Australia, Mexico, the United States, Japan, and Sweden. The largest topaz deposits are located in Brazil and Russia.
Different Types of Topaz
Imperial Topaz
Among the rarest varieties, Imperial Topaz gemstones can range from warm orange to deep rose. Also known as Precious Topaz, these gemstones can be very valuable.
White Topaz
White topaz is actually clear and is often used as an accent stone in jewelry. While lacking the sparkle of diamonds, these colorless gemstones are a cost-effective and lovely option for accentuating colored gemstones.
Blue Topaz
Blue topaz is a popular choice among jewelry shoppers, available in various tones and saturation levels. Notably, Swiss Blue (a light-toned, bright blue stone) and London Blue Topaz (a dark blue stone with moderate to dark tone and saturation) are the most sought-after varieties.
What Impacts The Value of a Topaz Gemstone?
The value of a topaz gemstone is affected by carat weight and clarity, but the most critical factor is color. The most valuable topaz stones are those with pink and red hues, followed by orange and yellow colors.
Color
The color of a topaz gemstone significantly impacts its value. Red or “Imperial Topaz” gemstones, representing less than 1% of facet-grade topaz, are highly prized. Gold or yellow topaz is more abundant and less valuable compared to those with red overtones.
Colorless or white topaz is abundant, and a wide variety of treated blue topaz is available. Through heat and radiation treatment, blue topaz can be acquired at reasonable prices in various tones.
Carat Weight/Size
As with most gemstones, carat weight significantly impacts topaz’s value. However, the rate of value increase differs based on the gemstone’s color. For example, Imperial Topaz’s value increases rapidly with size, whereas treated blue or pale yellow topaz sees a lesser price increase.
Cut
Topaz crystals, being unusually elongated, are frequently cut into pear and oval shapes. Strongly colored topaz gemstones may also be seen with an emerald cut.
Clarity
Topaz is typically referred to as “eye clear,” meaning inclusions are not visible to the naked eye. Unlike diamonds, topaz is not graded similarly; visible flaws would devalue the gemstone.
Ring Styles
You can manage the cost of topaz jewelry through its design. A solitaire topaz may be pricier than a halo ring with a center topaz. Using accent stones allows you to own a stunning topaz with a smaller carat size than required for a traditional solitaire design. Similarly, a three-stone ring design lets you showcase the beauty of the topaz without relying on a single large stone.
