Blue Sapphire


      Traditional blue sapphires are typically synthesized using titanium and iron to achieve the classic royal blue hue. However, two distinct variants of blue sapphires have recently emerged. The first is a czochralski sapphire characterized by an aqua-blue color, specifically cultivated for watch cases. The second type arises seemingly as anomalies in the production of green sapphires, achieved through the flame fusion method, which exhibits a significantly heightened presence of Co2+ ions. Currently, we are in the process of conducting chromophore analysis on the aqua sapphire. While we maintain an inventory of traditional blue czochralski sapphires, we refrain from stocking flame fusion blue sapphires within the conventional royal blue color spectrum due to inherent zoning issues arising from oxidation during the growth process.
