The Legacy of Topaz in Jewelry Design

The word “topaz” comes from Topazios, the Greek name for St. James Island on the Red Sea (presently known as Zabargad). And even though the Greeks believed that topaz protected the wearer and gave them strength, we unfortunately cannot promise that your antique and vintage topaz jewelry will give you any superhuman abilities.

Beloved by royalty, topazes were once believed to possess special powers for curing diseases and breaking magical spells. While they may not have supernatural properties, these autumnal gems are enchanting just the same.

It’s appropriate that as the temperatures cool and the leaves turn yellow, the birthstone for November is a gem found in autumnal hues. The deep browns, reds and oranges of the topaz, a stone once believed to have the power to cure fevers, is perfect for this time of year. In fact, the palette has also inspired a second birthstone for the month: citrine, which is less expensive and easier to find. Truth be told, topazes can be found in a wide variety of colors (which can get confusing since the blue topaz, along with turquoise, is a birthstone for the month of December), but it’s nice to wax poetic about the season.

The topaz can be blue, green, yellow, pink, purple and red. The colors of this allochromatic stone result from impurities in its crystal structure and are not part of its chemical composition, which is aluminum silicate fluoride hydroxide. The true color of topaz is no color at all. Isn’t it fascinating that a stone that can come in a variety of colors is colorless in its purest form?
