How is Topaz Made?<\/span><\/h2>\n\n\n\n

TOPAZ CHEMICAL COMPOSITION & FORMATION<\/span><\/h4>\n\n\n\n

A rare silicate mineral with a chemical composition of Al2SiO4(F,OH)2. Topaz is usually formed in the cavities and crevices of rhyolite, pegmatite, and other igneous rocks. The gemstone is mined from numerous places all over the world and natural stones display a golden brown or yellowish color.<\/p>\n\n\n\n

TOPAZ COLORS<\/span><\/h3>\n\n\n\n

You will find other colors of topaz, including red, gray. orange, green, blue (we will look at blue topaz in more detail later on), pink and purple. These colors are created either by impurities or by man-made treatments carried out to transform the hue of the natural gemstone.<\/p>\n\n\n\n

NATURAL TOPAZ ORIGIN<\/span><\/h3>\n\n\n\n

When explorers discovered a precious stone on the small Greek island of Topazios they decided to call it topaz, however, the gem actually turned out to be another precious stone\u2013peridot. Despite the confusion, the name stayed!<\/p>\n\n\n\n

First Discovery of Topaz<\/strong><\/p>\n\n\n\n

The first yellow crystals (modern-day topaz stones) were discovered in Germany in 1737, and then in 1740, a large gem was found in Brazil. However, it seems that mix-ups seem to go hand-in-hand with topaz.<\/p>\n\n\n\n

The huge stone was originally believed to be a diamond and was quickly fixed in place on the Portuguese crown. The gem was later identified as a topaz rather than a diamond \u2013 but kept its place on the royal headwear regardless.<\/p>\n\n\n\n

Modern-day Topaz Mining Deposits<\/strong><\/p>\n\n\n\n

Nowadays, topaz can be found in a number of places around the globe, including Pakistan, Afghanistan, Japan, Mexico, Madagascar, Burma, Australia, and the USA. Huge topaz crystals have been found in the past in Ukraine and Brazil.<\/p>\n\n\n\n

London Blue Topaz<\/span><\/h2>\n\n\n\n

For now, let\u2019s take a closer look at blue topaz. You will find a variety of blue topaz available, including Swiss Blue Topaz, London Blue Topaz, and Sky-Blue Topaz. Whilst natural blue topaz does exist, it is extremely rare. More often than not, blue topaz is man-made via treatments.<\/p>\n\n\n\n
