Topaz
A symbol of friendship, hope and true love.
📜 History and Stories
The English name Topaz may be derived from the ancient Greek name "Topazios" for the island of Zabargad in the Red Sea. Since ancient times, it has been recognized as a source of strength and wisdom. In Renaissance Europe, it was believed that topaz could break spells and calm anger.
History's most famous topaz misidentification is the "Braganza Diamond", a 1,680-carat monolith that was once considered the world's largest diamond before it was identified as a colorless topaz, set in the crown of Portugal.
🌍 Major Origin Distribution
The Brazilian state of Minas Gerais is the world's foremost producer of topaz, especially the highly prized Imperial Topaz. Pakistan and Russia also produce fine pink and sherry-colored topaz. The blue topaz commonly found on the market is sourced from all over the world, including Brazil, Nigeria and Sri Lanka.

🔥 The Birth of Blue: Irradiation and Heat Treatment
Natural blue topaz is very rare and extremely pale in color. The vast majority of bright blue topaz on the market is made from colorless topaz that has been irradiated and heat treated. This process is stable and widely accepted in the industry and produces a wide range of blue shades from "sky blue" to "London blue".
