Topaz is a beautiful gemstone belonging to the silicate family so topaz crystals range from transparent to translucent. This relatively hard gemstone comes in at 8 on the Mohs scale of mineral hardness, it is still eligible for chips and cracks due to its perfect cleavage. Since the cleavage of topaz gemstones is on the growth lines across the base, it is very fragile so be careful not to expose topaz jewelry to situations where it can be hit. Don't do household chores or play sports if you want your topaz jewelry to stay in one piece. To clean gemstone jewelry set with topaz, simply rub it with a jewelry cleaner and a soft toothbrush, then polish it with a rouge polishing cloth to bring out the gemstone's shine.
The wide range of colors of the topaz gemstone (colorless, blue, green, orange, red, and yellow) are a result of impurities like water and fluorine. The majority of topaz colors are caused by heat treatments and irradiation, but most topaz is a yellowish brown. Blue topaz gemstones always undergo heat treatments since the intense blue colors that are in such high demand in gemstone jewelry is not natural. Light blue topaz gemstones undergo gamma treatments and are then heated to reach the more vivid shades of blue. Blue topaz is actually the state gemstone of Texas.
Although topaz has been found in Afghanistan, Czech Republic, Germany, Italy, Japan, Mexico, Norway, California, Utah, Russia, and Pakistan, Sri Lanka, the majority of topaz gemstones are from Brazil.

Topaz is said to have the power to affect spirituality and improve creativity, tranquility, and wisdom. Orange topaz is the birthstone for the month of November.
