Like with diamonds, clarity has an impact on sapphires prices and rarity. Blue sapphires typically have some inclusions and those with extremely high clarity are rare and very valuable.
The majority of sapphires are treated with heat at extremely high temperatures to intensify their color, remove color-zoning, and improve their clarity. This is a common practice dating back thousand of years. Although “Heat Treated” these sapphires are 100% natural since they are mined from the earth and should not be confused with synthetic sapphires which are artifically grown have very little value.
Untreated sapphires means those that have not had any form of treatment to enhance their colour or clarity. This means these sapphires are in their purest form; they were mined and simply cut and polished to show their inner beauty. Most of the time untreated sapphires are referred to as unheated sapphires as the heat treatment is the most common enhancement.
Heated Sapphires Compared to Unheated Sapphires
With heated sapphires you will get a more vibrant, saturated stone for your budget. Most heated sapphires are eye-clean, with no inclusions visible to the naked eye. Unheated sapphires will have whatever inclusions were naturally created within them. Unheated sapphires are much more scarce and thus significantly more expensive than their heat-treated counterparts.
It is esstential the non-treated sapphires are accompanied by a certificate from a laboratory such as GIA, AGL, Gübelin, SSEF, or GRS.
