| White Topaz Gemstone Information Information * Loose gemstones * Jewelry links Topaz is the gemstone representing the 4th and 19th wedding anniversaries. The name topaz comes from Topazios; an island in the Red Sea. In 15th century Rome, topaz was used to detect poisons, calm anger, and break spells.
