🌍 GENERAL MATERIAL DESCRIPTION

  • Material Name:Colombian Emerald
  • Country of Origin : Russia
  • Growth Method:

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.

🏭 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.
