   Natural pink topaz has been highly prized by royalty and jewelry enthusiasts for centuries, particularly during the Victorian era. The stone's alluring pink hue, combined with its rarity and durability, made it a popular choice for jewelry designers and collectors.

   During the Victorian era, pink topaz became especially popular due to the romanticism and sentimentality of the time. Queen Victoria herself was a great admirer of pink topaz, and she owned several pieces of jewelry featuring the stone. This helped to popularize the gemstone even more, and it quickly became a favorite among the wealthy and fashionable.

   The demand for pink topaz during this time was so high that many gemstone dealers started to artificially treat other gemstones to mimic the pink color of topaz. However, the natural pink topaz remained the most prized and valuable.
