Lab Blue Sapphire


      Traditional royal blue sapphires are typically synthesized with titanium and iron to achieve their renowned color. However, recent advancements have led to the development of two new blue sapphire variants. The first is a Czochralski-grown sapphire featuring an aqua-blue tint, specifically designed for watch casings. The second is a unique outcome in the production of green sapphires using the flame fusion method, exhibiting a significant increase in Co2+ ion concentration. Currently, we are conducting a detailed analysis of the chromophores in these aqua sapphires. Our inventory includes the classic blue Czochralski sapphires, but we deliberately exclude the standard royal blue sapphires produced by flame fusion, due to issues with color consistency arising from oxidation processes during their growth.
