One of the November Birthstones is Topaz

The characteristics of Topaz

In recent decades, a variety of Topaz known as Blue Topaz has seen an increase in popularity. This color however, does not occur naturally and is a result of colorless Topaz undergoing specific treatments. In metaphysical beliefs, Topaz is said to improve curiosity and your sense of humor. The gem has been associated with compassion as well as communication.

Cut and Clarity for the November birthstone

Topaz typically has little to no inclusions, making these gemstones appear clean to the eye. For this reason, Topaz is a favorite alternative to diamonds and is sometimes used in diamond simulants as well. It is not uncommon to find incredibly large carat Topaz gems with a flawless appearance. Gem cutters take special care when faceting Topaz due to its cleavage potential. Topaz has a perfect cleavage, resulting in the stone potentially chipping if struck too hard. It’s also important for gem cutters to capitalize on the pleochroic nature, showcasing multiple colors. Topaz has been cut into all traditional and non-traditional shapes, though because of its typically elongated or column-like growth they are favorites in long ovals or pears and teardrops.

The value of Topaz

The more intense the color, the more valuable the specific Topaz gem is. Imperial Topaz named for its gold hue is especially favored, as well darker shades of the pink-red and orange-red spectrum. Especially valuable is the rare red Topaz which makes up less than half a percent of gem-quality Topaz found. Topaz tends to be a fairly affordable gemstone, making it a favorite for use in all levels of jewelry from costume to high-end.

Is Topaz ever treated?

All Blue Topaz is treated by irradiation first and heat treated to stabilize the color change. Due to the high amount of treatment on Blue Topaz, there have been instances of the blue color fading if left exposed to direct sunlight for a long period of time. Other Topaz colors are sometimes treated with similar methods to intensify the existing color.
