🌍 GENERAL MATERIAL DESCRIPTION
- Material Name:Colombian 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.
