Gem Note

🩷🔥😲 Wow! I've just cut the first stone from a large batch of Kyropoulos ruby we acquired a few months ago, and I'm thrilled with the result. This stone is absolutely stunning, showcasing a vibrant color that falls between Djeva Ruby #4 and Djeva Ruby #5. For anyone seeking a neon magenta/red gemstone, this one promises to be an extraordinary choice for a piece of jewelry that will endure for generations!

🌍 GENERAL MATERIAL DESCRIPTION

  • Material Name:Kyropoulos Ruby
  • Country of Origin : China
  • Growth Method: Kyropoulos

The Kyropoulos method, renowned for its ability to produce large, high-quality single crystals, has found a unique application in the creation of pulled ruby crystals. This technique involves the careful control of temperature and the environment to grow ruby crystals slowly, resulting in exceptionally large and pure specimens. The "pulled" aspect of these rubies refers to the method by which the crystal is drawn or pulled from the molten material, allowing for precise control over the crystal's orientation and internal structure. The result is a ruby of remarkable clarity and uniformity, prized for its optical properties. These Kyropoulos pulled rubies are especially valued in applications demanding the highest quality optical materials, such as in laser technology and precision instruments, where the purity and consistency of the crystal can significantly impact performance.

🏭 SPECIFIC Lot INFORMATION

This material comes with a fascinating backstory. Remarkably large Kyropoulos ruby crystals, intended for use in fiber optics, were successfully cultivated. It was a revelation to discover that rubies doped with chromium using the Kyropoulos method existed, a fact we were unaware of until recent reports surfaced. However, these crystal boules exhibited cracks and bubbles, leaving us to speculate whether these were the results of experimental efforts or flawed growth processes, thus casting doubt on the viability of future production. Interestingly, this type of ruby demonstrates a range of hues—from neon red/pink to deeper reds, similar to those hues found in Djeva Ruby (grades 3, 4, and 5). In our view, these rubies exhibit the ideal coloration, marked by vibrant tones without any loss of intensity and extinction.
