The fine golden-yellow variety, known as Imperial Topaz, is relatively scarce. Topaz colors are rarely vivid. The most common color is yellow with a red tint; the most valuable is pink to reddish. The coloring agents are iron and chromium.
The name topaz is most probably derived from an island in the Red Sea, "Topazos", today called Zabargad, the ancient source of peridot. In former times all golden-brown and sometimes also green gemstones were called topaz, which caused sufficient confusion such that today real topaz is referred to as precious topaz. Topaz is the birthstone for those who are born in the month of November. 925 Weight: 25 g Diameter: 38,61 mm Mintage: 2000 Pcs Worldwide Finish: Antique Finish Certificate COA: Yes Box: Yes.
