๐ŸŒ GENERAL MATERIAL DESCRIPTION

  • Material Name:FF Teal
  • Country of Origin : Thailand
  • Growth Method: Flame Fusion

Cobalt flame fusion sapphire exhibits color variations due to the ability of cobalt to exist in two distinct valence states: Co2+ and Co3+, which impart blue and green hues, respectively. The majority of gemstones cut from this material feature a captivating teal shade, resulting from a blend of these two colors. Occasionally, cobalt may aggregate into minute cobalt aluminate crystals. Each gem cut from this material possesses a distinct uniqueness attributable to varying proportions of Co2+ and Co3+ within the crystal lattice.
