Lighter colors like Sky-Blue color are produced by electrons as well as the darker blue recognized as London or Swiss Blue is developed by exposure to neutrons. The process can take minutes or years, as high-energy processes call for that the topaz is stored just before it can be released safely.



The pale or colorless Topaz used within the approach is mined in Brazil , Sri Lanka , Nigeria , and China . The gemstones are generally reduce just before they're treated.



Legend says that Topaz dispels enchantment. The ancient Greeks believed that a Topaz gemstone has the energy to raise strength and make its wearer invisible in occasions of emergency. Topaz gemstones ewre also stated to modify color inside the presence of poisoned food or drink.



In 1969, Blue Topaz was named the state gem of Texas to celebrate a modest deposit of all-natural pale Blue Topaz that was located within the state.



Simply because Blue Topaz is readily offered and affordable, it might be located within a wide variety of shapes and sizes, such as unusual cuts. Large dramatic gems are readily out there.

Most topaz is clear (white) when it's mined. Then it really is treated by various strategies to turn into a colored gemstone. Swiss blue and london blue topaz is treated by radiation - from time to time taking years of a cooling period to total prior to the gems are in a position to be handled. A brand new process was developed by Azotic, a US-based science analysis enterprise, to apply a durable coating towards the pavilion (bottom) with the gemstone with optical properties to give the gem color.

Since these gems possess a coating on the pavilion, they're going to seem different from the face versus the bottom angles. The coating is semi-permanent - it may be damaged with harsh chemical compounds or ultrasonic cleaner. The catch 22 is, untreated topaz shouldn't be handled with harsh chemicals or in an ultrasonic cleaner - so it is actually actually about as permanent as any other topaz would be.

Topaz is a gemstone of all colors, and its most valuable color can be a golden orange-yellow, known as "imperial topaz". Topaz is frequently thought of as a sky-blue gem, however it was not till this century that blue topaz became widespread on the gem market. All-natural blue topaz using a deep hue is incredibly uncommon in nature; colorless to light hued stones are heat-treated to attain the blue color. Likewise, topaz hardly ever occurs naturally in pink; practically all pink topaz is heat treated from yellow or brownish material.



Some topaz from Russian localities are notorious for fading upon prolonged exposure to light. Stones from these localities are undesirable as gems. One need to always inquire about the origin from the topaz before buying it to make certain it is going to not fade.
