Most modern translations of the Bible refer to it as being the second stone of the first row in the Breastplate of Aaron. However, there is argument over the fact that stone mentioned may have actually been chrysolite instead.

Topaz is currently the official mineral of the State of Texas.

Colors of Topaz

Topaz is found to occur naturally in a wide range of colors. Some of these include: red, yellow, orange, pink, gold, blue, brown and clear. Natural pale to medium blue topaz is typically enhanced by radiation in order to deepen the color and produce the popular colors seen on the market today.

Sky Blue

The sky blue color is the lightest of the three most popular shades. The color can be natural, but is most often silver topaz that has been irradiated or heated to produce color.

Swiss Blue

This is a gorgeous shade of blue that is popular for use in sterling silver as well as fine gold jewelry. This shade is typically more expensive than sky blue because it takes a longer time to achieve the deep blue color.

London Blue

This is the darkest shade of blue available in topaz on the market. The color is close to that of blue diamonds. It is the most expensive choice in treated topaz because it takes a long time to achieve the deep blue color.


Topaz of all colors is currently found in Afghanistan, the Czech Republic, Germany, Sri Lanka, Norway, Italy, Japan, Sweden, Pakistan, Brazil, Mexico and the United States.

Brazil currently is known to have the largest clear topaz crystals. Some of them reach boulder size and can weigh in at over 100 pounds!


Most colors of topaz have been treated to bring out deeper, richer colors in the stones. A wide variety of deep blue and blue-green shades can be brought out by using a combination of heat treatment and irradiation (a bombardment of X-rays, gamma rays or ultra-violet rays.).

Care and Cleaning

Just about any commercial jewelry cleaner should be fine to use with your topaz. You may also use a soft brush and luke-warm water mixed with a mild soap. You should avoid using Ultrasonic jewelry cleaners with your stones. Blue topaz, or any other color, is hard and resists scratching. However, due to its internal structure, it can break or split when subjected to hard blows or extreme changes in temperature.
