Topaz is a wonderful gemstone that is extremely popular and found in many regions around the world. Topaz has been known to man for millennia and the name Topaz was generally used for any stone that was yellow in color.
Topaz is a type of fluorosilicate. It is created from many elements including aluminum, fluoride, silicon and oxygen. Besides these elements, it also can include trace elements that can help create or enhance the color of the Topaz. Topaz is found usually near silica rocks that are volcanic in origin. It is also found in volcanic cavities and in pegmatites.
Topaz is pretty hard and scores an 8 on the Moh’s hardness scale. However, it should be noted that because of its cleavage, it can be very brittle at times and must be cut properly. Topaz comes in many colors including yellow, blue, green, pale pink, red, lavender, brown and colorless. Usually blue, colorless and yellow are the most popular and red and lavender are the most rare.
Topaz sold commercially is usually enhanced by heating or radiating the color centers. Usually blue is the most enhanced and certain Topaz gemstones are known to fade due to intense heat or even sunlight. Topaz is available in many regions and is specifically mined in Brazil, Mexico, Africa, Sri Lanka and Myanmar. However, some colors are usually mined at specific locations. For instance, blue from Brazil, pink from Sri Lanka and yellow from Germany. |
