18K White Gold Natural Blue Topaz Gemstone Drop Earring for Women

Topaz

Golden topaz is known as “precious topaz” because it is the most valuable colour of topaz. Possibly from the Sanskrit word for fire (tapas), topaz contains about 20% water and fluorine. The colour of the stone is determined by the relative proportions of these impurities. Those with more water are yellow to brown; those with more fluorine are typically blue or colourless.
