💙💙💙 This breathtaking cobalt-doped YAG is a remarkable alternative to the finest Swiss blue topaz, offering the same stunning, vivid blue hue with added benefits. Not only does it closely mimic the brilliance of Swiss blue topaz, but it also features a higher refractive index, giving it enhanced brilliance and sparkle. Additionally, its slightly improved durability makes it more resistant to wear, ensuring that it will maintain its beauty over time. This exceptional gemstone is perfect for creating a show-stopping piece of jewelry that combines beauty, durability, and timeless elegance, making it an ideal choice for a one-of-a-kind piece that will last a lifetime.

🌍 GENERAL MATERIAL DESCRIPTION

  • Material Name:Co:YAG
  • Country of Origin : Russia
  • Growth Method: HDSM

A single, unidentified producer, as we understand it, employs the HDSM method to cultivate YAG doped with cobalt (which we believe to be cobalt), exclusively for the gemstone market, with no known scientific applications. This material is available in a spectrum of Swiss blue hues, with the lightest being extremely faint. The outcome is an exceptionally brilliant and strikingly vivid blue gemstone. The deeper variants yield gems of remarkable quality, boasting superior dispersion, hardness, and refractive index compared to irradiated Swiss blue topaz, making them stand out in the realm of materials with a Mohs hardness exceeding 8. Among the most vibrant green to blue color ranges found in any substance are those of Yb:YAG, Co:YAG, and V:YAG.
