Product History
The Artisan Designer Floral Piece is actually created from Pure Silver PMC3 clay and is a much higher Silver content than that of the Sterling Silver you purchase elsewhere. Its Silver content is .999 pure silver.
True topaz is a silicate of alumina, containing hydroxl and fluorine; hardness, 8; specific gravity, 3.4 to 3.6. Being three and one half times as heavy as water, topaz can be readily distinguished from other stones resembling it by those accustomed to handling them. Topaz cannot be fused on charcoal before the blowpipe, but it is partially decomposed by sulphuric acid. Its hardness enables it to take a high polish, and the colourless variety has been cut in brilliant or rose form so as to resemble the diamond, for which it might readily pass in day-light. However, it is but weakly doubly refractive and dispersive, and its comparative softness makes its distinction from the diamond a simple matter. Although infusible, when sufficiently heated, the faces of crystallisation of topaz become covered with small blisters which crack as soon as formed; and with borax it slowly forms a clear glass. Some varieties assume a wine yellow or pink tinge when heated. The rose-pink topaz sometimes appearing mounted in jewelry, is not natural; the delicate tint of this gem with an artificial complexion results from a simple process called "pinking," applied to yellow or brown kinds. A topaz selected to be "pinked" is packed in magnesia, asbestos, or lime, and carefully and gradually heated to a low red heat; the stone then being slowly cooled. If the temperature attained has not been sufficiently high, the desired rose-petal tint is not obtained and a salmon tint appears; if the temperature rises too high, or is too long continued, the colour completely disappears. Pulverised topaz changes to green the blue solution of violets. Topaz generally becomes electric by heat, and if both terminations of the subject specimen are perfect, polarity will be developed; transparent varieties are susceptible to electrical excitation by friction.
Citrine is one of the most valuable forms of quartz. The most common use is as a gem by jewelers but is also valuable to mineral collectors. It has also substituted for the more expensive gem Topaz.
Citrine is transparent to translucent and yellow to gold-brown in color with a vitreous luster. The name citrine is derived from the old French word for lemon, citrin. Its color comes from the presence of Iron impurities within the crystal. The darker colored Citrine crystals, named Madeira for their color’s resemblance to Madeira wines, are generally more valuable. Natural citrine is rare and most natural occurs when Amethyst formations are near natural heat sources in the Earth’s crust. Citrine becomes dark brown when exposed to x-rays and white when heated.
