Unveil the Splendour of Topaz Gemstones

Topaz gemstones display an array of colours, with most gem-quality topaz ranging from transparent to translucent. Renowned for its dazzling vitreous lustre, topaz is November's birthstone and the zodiac gemstone for Scorpio. With a hardness of 8, topaz is a durable gemstone believed to promote good health when placed in a home.

Topaz Treatments and Identification Techniques

Topaz can undergo heat and irradiation treatments to modify its colour, while coatings may be applied to create green shades and optical effects. Dichroscopes and Chelsea colour filters can be employed to help identify topaz gemstones.
