Gemstones are beautiful and precious, but did you know that many of them undergo treatments to enhance their appearance? Gemstone treatments are common in the industry and can significantly affect the value and durability of a gemstone. In this blog post, we will explore some of the most common gemstone treatment methods and their impact on the gemstone.

What are gemstone treatments?

Gemstone treatments refer to any process that alters the appearance or properties of a gemstone. These treatments can include heating, irradiation, filling, and coating. The goal of these treatments is to improve the color, clarity, or durability of the gemstone.

Heating

Heating is one of the most common gemstone treatment methods. It involves subjecting the gemstone to high temperatures to enhance its color or clarity. For example, heating can remove impurities and improve the color of sapphires and rubies. This treatment is widely accepted in the industry and does not significantly affect the value of the gemstone.

Irradiation

Irradiation is another popular treatment method, especially for colored gemstones. It involves exposing the gemstone to radiation to alter its color. For example, irradiation can turn a pale yellow diamond into a vivid blue diamond. However, it is important to note that not all irradiated gemstones are stable. Some may require additional treatments to stabilize their color.

Filling

Filling is a treatment method used to improve the clarity of gemstones. It involves filling the fractures or cavities in a gemstone with a substance that enhances its appearance. For example, emeralds are often filled with oils or resins to minimize the visibility of their natural inclusions. While filling can improve the gemstone's appearance, it can also make it more susceptible to damage and require special care.

Coating

Coating is a treatment method that involves applying a thin layer of material to the surface of a gemstone. This layer can enhance the color or add a specific effect, such as iridescence. However, coatings are generally not permanent and can wear off over time, affecting the appearance of the gemstone.

Conclusion

Gemstone treatments are a common practice in the industry, and it is important for consumers to be aware of them. While some treatments are widely accepted and do not significantly affect the value of the gemstone, others may require special care or have a temporary effect. When purchasing gemstones, it is essential to inquire about any treatments they have undergone and make an informed decision based on your preferences and the gemstone's long-term durability.
