Topaz
The name Topaz is thought to trace back to the ancient Greek Topazion, a reference to a small island in the Red Sea where a yellow gemstone, likely not Topaz at all, was mined in antiquity. Over centuries, the name became attached to the mineral we know today: one of Earth’s most brilliant and diverse gemstones. Chemically, Topaz is a silicate mineral of aluminium and fluorine, remarkable for its hardness and its ability to occur in an extraordinary range of colours.
Today, Brazil remains the primary source, producing both imperial and colourless varieties, but notable deposits also come from Pakistan’s Katlang region, Nigeria, Sri Lanka, and Russia. Beyond its beauty, Topaz offers a study in gemology itself; a gemstone whose history, chemistry, and kaleidoscope of colour make it as much a subject of fascination as it is an object of adornment.
