🌍 GENERAL MATERIAL DESCRIPTION

  • Material Name:Djeva 3
  • Country of Origin : Switzerland
  • Growth Method: Flame Fusion

Djeva #3 is a chromium-doped corundum grown via flame fusion by the Swiss company Djeva. Renowned for its intensely saturated neon pink color, it represents the brightest and purest pink achievable in lab-grown gemstones. With higher chromium levels, like in Djeva #4, the color shifts toward magenta and ruby red. When expertly cut, Djeva #3 radiates unmatched brilliance, making it perfect for bold, standout jewelry pieces.

🏭 SPECIFIC Lot INFORMATION

We acquired several vintage lots from Thai cutting houses following Djeva's shutdown in 2021.
