What is Diffused Blue Sapphire?

Updated: Feb 26, 2023

What is Diffused Blue Sapphire and Why is it Becoming Increasingly Popular in the Jewelry Industry?




Sapphires are one of the most popular gemstones in the world, prized for their rich blue color and durability. However, not all sapphires are created equal, and some are treated to enhance their appearance. One such treatment is called diffusion, which involves adding trace elements to the surface of the gemstone to improve its color.


Diffusion is a process in which a gemstone is heated to high temperatures and infused with a coloring agent, typically titanium or chromium. The heat causes the coloring agent to diffuse into the surface of the gemstone, creating a layer of color that can improve the gemstone's appearance. This process can be used to enhance the natural color of a sapphire or to create a new color altogether.



The Diffusion Treatment Process


The Diffusion Treatment process is a method used to enhance the color of a natural sapphire. The process involves infusing a small amount of beryllium into the surface of the sapphire, creating a rich, deep blue color. This treatment is commonly used on sapphires that are originally a pale blue or gray color, as it can significantly improve their appearance and value.


The diffusion process is accomplished by heating the sapphire in a closed container with beryllium. The high temperatures cause the beryllium to diffuse into the surface of the sapphire, creating the desired blue color. The process is typically done at temperatures between 1400 and 1800 degrees Celsius, and it can take anywhere from a few minutes to several hours, depending on the desired color and intensity.


It's important to note that while the diffusion treatment can improve the appearance of a sapphire, it also makes it less valuable than a natural, unheated sapphire. Therefore, it's important for buyers to be aware of the treatment and its effect on the value of the stone. However, for those on a budget or looking for a specific color, diffusion treated sapphires can be a great option.


Another thing to consider is that the diffusion treatment does not change the physical and chemical properties of the sapphire, it only affects the color. Therefore, the hardness and durability of the sapphire will remain the same, making it a suitable choice for daily wear.


In recent years, the diffusion treatment has become more popular in the gemstone market, and it's widely used to produce affordable, high-quality sapphires. With the diffusion treatment, consumers can have access to beautiful sapphires at a lower cost, making it a great choice for anyone looking to add a touch of elegance to their jewelry collection.


Overall, the Diffusion Treatment is a popular way to enhance the color of a natural sapphire, making it more beautiful and accessible for consumers. However, it's important to be aware of the effect on the sapphire's value, and to understand that it's a treated gemstone. As always, it's crucial to buy from a reputable source and to ask for a certificate of authenticity when purchasing a diffusion-treated sapphire.
