What does it mean if a sapphire is heated or treated versus unheated?
Throughout history, it has been a common practice to treat sapphires in some way to enhance their color and clarity. There are various temperatures that sapphires are heated to from 400 degrees all the way to 1700! And there are also chemical treatments. All of these techniques improve a sapphire’s color and clarity. Untreated sapphire means the stone has not undergone any processes to increase quality.
Why does heat treating a sapphire make it less desirable if it increases transparency?
Often very low grade sapphires are treated with chemicals to alter their color, transforming stones that would not be market grade into salable pieces. These processes may increase the stone’s beauty, but not its value.
What is the difference between natural and treated sapphires?
A sapphire can be listed as “natural” simply because it is not lab created. However, “natural” does not mean the sapphire has not undergone any alterations. The key term is “untreated,” meaning a sapphire is natural (not lab created) and has not been subject to any chemical or heat treatments. Approximately only 0.5 - 1% of the sapphires discovered are of gem quality without treatment. Natural untreated sapphires are far more uncommon and valuable than treated and chemically altered stones.
Are dark or light colored sapphires considered higher quality?
Generally speaking, darker sapphires are more desirable. Although, its more about the saturation of color. If they go too dark they can run black and that's also not desirable. Ultimately it comes down to personal preference.
What should I look for if I'm interested in darker sapphires? For example what words should I use to describe a high quality darker sapphire?
