Topaz is an infamous stone that has been known for millennia. The name Topaz was first given by the Greeks (called topazos), which meant any yellow stone. Unfortunately, this custom of calling any yellow stone Topaz lasted for thousands of years and in many ways still today. Many times Topaz is incorrectly labeled as Citrine or Yellow Quartz. It is neither of these gemstones. Topaz not only comes in a wonderful yellow, but a host of other great hues.
Topaz is a fluorosilicate. Fluorosilicates include aluminum, fluoride, silicon and oxygen. They also have other trace elements such as chromium that can cause different colors within the Topaz. Topaz are known to have color centers and while color centers are not fully understood, the color of Topaz can change, usually with the help of intense heat or radiation.
Topaz comes in a wealth of beautiful colors including blue, pink, red, lavender, yellow, brown, orange, colorless and green. It should be noted that both red and lavender are usually extremely rare colors. Colorless topaz and yellow are fairly common.
It should be noted that Blue Topaz is one of the most popular gemstones sold commercially, usually due to its affordability and beautiful rich hues. The vast majority of Blue Topaz is treated, usually with heat or radiation to enhance the color of the Topaz. Usually Blue Topaz is formed from colorless Topaz, but it can be created from Blue or even yellow Topaz.
Topaz does have certain mystical and magical qualities associated with it, such as protecting one from illness or evil, to make one fertile and to make one happy or stable emotionally.
