Topas smykkesten Color
Topaz ranges from colorless (white) to yellow, orange, red-brown, light to dark-blue, pink to red, violet and light-green. This is the reason why it can be mistaken for many other gemstones. Naturally colored topaz gets its color from iron and chromium; the impurities cause color, whereas pure topaz is colorless. Most unadulterated topaz is colorless or pale blue. The most rare and valuable topaz is yellow, or pink to reddish-orange, and is known as “imperial topaz” or “precious topaz”. Some yellowish-brown topaz gems can gradually fade when continually exposed to daylight. Red and violet topaz is incredibly rare. A lot of topaz is treated in order to enhance the color. Reputable gem sellers declare any enhancements.
Topas smykkesten Clarity and Luster
Topaz is transparent to translucent. It exhibits high clarity with few inclusions, so topaz gemstones can be examined by the naked eye and found to be “eye clean”, which means that no imperfections can be seen. Topaz is highly prized for its brilliance and vitreous (glassy) luster.
Topas smykkesten Cut and Shape
Topaz is a very versatile material. Therefore it can be cut into a great variety of shapes, such as square, round, octagon, pear, oval, heart and even fancy shapes such as fish or birds. Strongly colored gemstones are usually scissor cut whereas weakly colored stones are generally brilliantly cut. The facets show off the clarity and brilliance of the gem. When topaz has irregular inclusions, it is often cabochon cut. Its hardness makes it resistant to scratches. However, lapidarists must handle topaz carefully, due to its perfect cleavage, which means that it can easily fracture.
Topas smykkesten Treatment
Topaz is often enhanced to produce the most desirable colors. The most popular color for topaz is blue, but in nature, blue topaz is usually pale blue rather than bright or deep blue. The brilliant blue shades of topaz are usually achieved by artificial means. Topaz is exposed to radiation (a process known as irradiation) and then usually heated, to produce striking blue colors. A deep blue enhanced topaz is known as “London blue”; medium blue is called “Swiss blue” and light-blue is termed “sky blue”. This blue color treatment is usually performed on grayish-blue or silver-gray gemstones. The darker blue shades are more valuable because more energy is needed to produce darker colors. Orange-brown topaz is heat-treated during a process known as “pinking”, which produces a purplish-pink color.
Topas smykkesten Coating
Topaz can also be coated to change its color. Coatings are not permanent and can gradually fade over time. Stones that have been treated in this way should not be re-cut, since the coating will be taken off and reveal a different, undesirable color inside. Coating treatment produces iridescent stones known as “mystic topaz”. Azotic topaz is white topaz that has been color-enhanced by coating it with a thin film which gives it rainbow colors. It is named after the company that patented the Azotic process. Topaz is also coated to produce vivid pink and imitation “imperial topaz”. White topaz can also be exposed to diffusion treatment, which means that it is exposed to chemicals and heat, to change the surface color. This treatment is performed to produce “green topaz”, but the treatment only changes the surface color, so that if the gem is re-cut, the original, undesirable color will be revealed. As with irradiation, any surface treatments or coatings are declared by reputable gem sellers. Natural topaz can also be found.
Topaz Facts, Information and Description
Topaz occurs in a wide range of colors including red, orange, peach, pink, gold, yellow, brown and clear and is found in Brazil, Sri Lanka, Pakistan and Russia. Naturally pale to medium blue topaz is enhanced by irradiation to produce a more intense blue color.
The most famous topaz is actually a colorless topaz that was originally thought to be a diamond. It is a 1680 carat stone known as the “Braganza Diamond” set in the Portuguese Crown Jewels. Another beautiful topaz is in the Green Vault in Dresden which has one of the world’s most important gem collections.
Although topaz is a very hard gemstone, an 8 on the Mohs scale of hardness, it can be split with a single blow and should be protected from hard knocks.
