QUALITY ROUGH

Topaz is commonly associated with silicic igneous rocks of the granite and rhyolite type. It typically crystallizes in granitic pegmatites or in vapor cavities in rhyolite lava flows.

Pure topaz is colorless and transparent but is usually tinted by impurities; typical topaz is wine, straw yellow, pale gray or reddish-orange. It can also be made white, pale green, blue, gold, pink (rare), reddish-yellow or opaque to transparent/translucent.

Orange topaz, also known as precious topaz, is the traditional November birthstone.

Imperial topaz is yellow, pink (rare, if natural) or pink-orange. Brazilian Imperial Topaz can often have a beautiful bright yellow to deep golden brown hue, sometimes even violet. Many brown or pale topazes are treated to make them bright yellow, gold, pink or violet colored. This variety is the most sought-after and highly valued among the topaz gems

T

Treatments-When treated, yellow topaz often becomes reddish-pink. Only stones of a brown-yellow color yield the pink; the pale yellow ones usually turn white. The pink color is stable. Topaz can also be irradiated, turning the stone blue, ranging from a light pure color to very dark almost electric blue AS WITH ALL OUR STOCK YOU MAY RETURN IT FOR A FULL REFUND IF NOT PLEASED .
