Topaz is a fascinating gemstone renowned for its radiant beauty and rich colour variations. It belongs to the silicate mineral family and is one of the hardest naturally occurring minerals, with a Mohs hardness rating of 8 on a scale of 1 to 10. The name “topaz” is derived from the Greek word “topazos,” which means “to seek.”

One of the most striking features of topaz is its vibrant hues, which can range from colourless to yellow, orange, pink, red, brown, and even rare shades of blue. The intensity and saturation of colour are influenced by impurities and the presence of certain trace elements within the crystal structure. Blue topaz, in particular, has gained immense popularity in recent years due to its captivating sky-blue shade.
