Product Detail:

Pink Sapphire reddish sapphire: earlier, the international gem community believed that only corundum with medium depth to dark red or purplish red can be called ruby. Those that turn red light to very light are called pink sapphires. However, at the third session of the International Association of colored gemstones held in Sri Lanka in May 1989, it was decided to abolish the name and include such gemstones into the scope of Ruby (but some people still disagree with this resolution and advocate that some corundum gemstones with non ruby red should still be called “Sapphire”. For example, the “synthetic peach sapphire” produced by Guilin gem Research Institute in China). It is known that the purple sapphire produced in Sri Lanka can obtain the ruby previously known as pink sapphire after heating to 450 ℃, while some pink sapphires can turn into beautiful orange sapphire with water red tone after heating to 1500 ℃, and the sapphire of this color is called “batpalard stone”.
