Topaz was named after the legendary island of Topazios, which lies off the coast of Egypt, or the Sanskrit word 'tapas', which means heat or fire. Topaz stands out for its exceptionally wide color range, which, in addition to classic brown, includes variously saturated shades of blue, green, yellow, orange, red, pink and purple.
