How was the ruby altered? This question often arises when examining the fascinating history and transformation of the precious gemstone. Rubies, with their deep red hues and hardness, have been cherished for centuries, and their beauty has been enhanced through various methods of alteration. In this article, we will explore the different ways in which rubies have been altered throughout history, from ancient times to the modern era.

Rubies, like other gemstones, can be subjected to various treatments to improve their appearance or to restore their luster. One of the most common alterations is heat treatment, which has been used for thousands of years. This process involves heating the ruby to a high temperature, which can improve its color and clarity. The heat treatment can range from low temperatures that enhance the color slightly to high temperatures that can completely transform the stone’s appearance.

Another popular method of altering rubies is oiling. This technique involves treating the gemstone with a transparent oil to improve its clarity and reduce the appearance of inclusions. Oiling is a relatively simple process and can be done by the jeweler or the owner of the ruby. However, it is important to note that oiled rubies require special care, as the oil can be removed or altered over time.

In some cases, rubies may be treated with lead glass or boric acid to fill in inclusions and improve their clarity. This process, known as glass filling, can make the stone appear more transparent and less cloudy. While glass filling can enhance the appearance of a ruby, it is considered a controversial treatment, as it can be difficult to detect and may not be permanent.

In recent years, advancements in technology have led to the development of new methods for altering rubies. One such method is diffusion, which involves introducing a color-enhancing agent into the crystal lattice of the ruby. This process can produce a more even and vibrant color than traditional heat treatment and is often used to enhance the color of low-quality rubies.

Despite the various methods of altering rubies, it is crucial for consumers to be aware of these treatments and to understand their potential impact on the value and longevity of the gemstone. Many reputable gemological laboratories offer testing services to identify and authenticate gemstones, including rubies, to ensure that buyers are making informed decisions.

In conclusion, the ruby, a gemstone that has captivated the world for centuries, has been altered in numerous ways to enhance its beauty and value. From ancient heat treatments to modern diffusion techniques, the history of ruby alteration is a testament to the ingenuity and dedication of gemstone artisans. As consumers continue to seek out the perfect ruby, it is essential to understand the various methods of alteration and the potential implications they may have on the gemstone’s quality and longevity.
