Did You Know? The Difference Between Natural Heat and BE Heat Rubies and Sapphires

Natural Heat vs. BE Heat: A Closer Look at Ruby and Sapphire

Rubies and sapphires, two of the most sought-after gemstones, are often treated to enhance their color and clarity. One common treatment is heating, which can improve the color intensity and remove impurities. However, there are two main types of heating: natural heat and BE heat.

Natural Heat Treatment:

Process: This method involves heating the gemstones in a kiln at high temperatures to improve their color. Natural heat treatments have been used for centuries and are considered a traditional method of enhancing gemstones.
Benefits: Natural heat treatments generally do not affect the gemstone's structure or durability.
Disadvantages: The process can be time-consuming and may not always produce the desired results.

BE Heat Treatment:

Process: BE (Berthelot Effect) heat treatment is a more recent technique that involves heating gemstones in a sealed capsule with a reducing agent. This process can produce more dramatic color changes than natural heat treatment.
Benefits: BE heat treatment can often produce more vibrant and desirable colors in rubies and sapphires.
Disadvantages: Some experts believe that BE heat treatment can affect the gemstone's durability and may not be as stable as natural heat treatment.

Identifying the Difference:

It can be difficult to distinguish between natural heat and BE heat treated rubies and sapphires with the naked eye. However, gemologists can use specialized equipment to analyze the gemstone's internal structure and identify the type of treatment it has undergone.

Choosing the Right Treatment:

Whether you prefer natural heat or BE heat treated rubies and sapphires is a matter of personal preference. Natural heat treatments are generally considered more traditional, while BE heat treatments can produce more vibrant colors. Ultimately, the best choice depends on your budget, desired color, and ethical considerations.

Conclusion:

Both natural heat and BE heat treatments are commonly used to enhance the color of rubies and sapphires. Understanding the differences between these treatments can help you make an informed decision when purchasing these precious gemstones.
