Topaz is believed to have originated from the ancient Greek island of Topazios in the Red Sea, which was known for its yellow gemstones. Sky Blue Topaz is not a naturally occurring colour for Topaz; instead, it is typically colourless or pale yellow when found in nature. The striking blue hue is achieved through a combination of heat treatment and irradiation, a process that has been practiced for centuries to enhance the stone's natural beauty.

In ancient Egypt Topaz was associated with the sun god Ra and was believed to bestow protection and prosperity upon its wearer. Similarly, in ancient Greece and Rome, Topaz was considered a symbol of strength and vitality, with the ability to grant its wearer courage and wisdom.
