Heated vs Unheated Sapphires, which is best for you?

Updated: Mar 27, 2023

Sapphires are a popular gemstone that can be found in a range of colors, from blue to pink to yellow. They are prized for their durability and luster, making them a popular choice for jewelry. When it comes to sapphires, there are two main categories: heated and unheated.

Heated sapphires are those that have been subjected to high temperatures to enhance their color and clarity. This process is done to improve the appearance of the gemstone, as heating can remove or reduce the visibility of inclusions (flaws) and improve the saturation and hue of the color.

Unheated sapphires, on the other hand, have not been subjected to any high temperatures or other treatments to enhance their color or clarity. These gems are considered to be more rare and valuable, as they are in their natural state and have not been altered in any way.

There is some debate among gemstone enthusiasts about whether heated or unheated sapphires are better. Those who prefer heated sapphires argue that the process can improve the overall appearance of the stone, making it more vibrant and appealing. They also note that heated sapphires are more readily available.

On the other hand, those who prefer unheated sapphires point out that these gems are rarer and more valuable, as they are in their natural state and have not been altered in any way. They argue that unheated sapphires have a certain beauty and uniqueness that cannot be replicated by heated stones.

Ultimately, the choice between heated and unheated sapphires comes down to personal preference. Some people prefer the enhanced appearance of heated sapphires, while others prefer the natural beauty of unheated stones.
