๐ŸŒ GENERAL MATERIAL DESCRIPTION

  • Material Name:Columbian Emerald
  • Country of Origin : Russia
  • Growth Method: Hydrothermal

The "Colombian" color hydrothermal lab-created emerald is renowned for its vividly brilliant coloration among synthetic gemstones. It demonstrates dichroism, displaying a rich grass-green color along the C axis and a striking teal along the A axis. These axes merge seamlessly to produce a gemstone with a dazzling green-blue glow. Crafting this material is particularly expensive because the autoclaves must be lined with gold or platinum to shield against the acidic solution's corrosive effects during the growth process.

๐Ÿญ SPECIFIC Lot INFORMATION

We prioritize sourcing the highest quality and most impeccable crystals. In particular, we strive to secure crystals that are 13 to 15mm thick, a rarity in the A grade category.
