Sure, here is a brief blog on types of treatments for gemstones:
Gemstones are natural minerals that have been cut and polished to enhance their beauty. However, in order to make them more attractive or valuable, some gemstones undergo various types of treatments. Some of the most common treatments include:
Heat treatment: This is one of the most common treatments used to improve the color of gemstones. Heat is used to change the color, clarity or to remove inclusions. For example, sapphires are often heat treated to make them a more intense blue color.
Irradiation: This is a process where gemstones are exposed to radiation, which can change their color. For example, irradiation can be used to make diamonds appear yellow or brown.
Dyeing: This is a process where a gemstone is dyed to change its color. For example, some turquoise is dyed to make it a more vibrant blue color.
Fracture filling: This is a process where fractures or cracks in a gemstone are filled with a clear or colored substance. This can improve the appearance of the gemstone, but it can also reduce its value.
Oil or resin filling: This is a process where oil or resin is used to fill surface-reaching fractures or cavities of a gemstone. This can improve the appearance of the gemstone, but it can also reduce its value.
It is important to note that treated gemstones are often worth less than natural gemstones. Therefore, it is important to always ask the seller if a gemstone has been treated and to get a certificate of authenticity.
In general, it is recommended to purchase untreated gemstones if you are looking for a high-quality, valuable piece.
