Lab Created Gemstones – Synthetic Corundum – Lab Created Ruby – Synthetic Ruby

About Lab Created Ruby

Lab Created Ruby is a synthetic variety of Corundum (Al₂O₃) with a beautiful pink to deep blood-red color. It offers outstanding brilliance, excellent durability, and a hardness of 9 on the Mohs scale. Therefore, it is an ideal gemstone for jewelry and industrial applications.

In ancient times, rubies were often considered more valuable than diamonds. According to Chinese legend, Emperor Kublai Khan offered an entire city in exchange for a single ruby. Many cultures believed that ruby enhanced awareness, improved concentration, and inspired courage. Furthermore, its deep red color symbolized the power of the sun. Some legends even claimed that placing a ruby in water would make the water boil.

Today, manufacturers use ruby crystals in watches, medical instruments, scientific equipment, and laser technology because of their exceptional optical and physical properties.

Unusual Properties

Many people associate ruby with confidence, courage, mental focus, and increased awareness. In addition, its exceptional hardness makes it suitable for everyday jewelry.

Both natural and lab created rubies also play an important role in modern technology. Manufacturers use them in watchmaking, medical instruments, precision equipment, and surgical lasers because they provide excellent optical performance.

Treatment

Manufacturers produce Lab Created Rubies using two primary methods. Both methods combine aluminum oxide with chromium to create the rich red color that characterizes ruby. However, each method produces gemstones with different growth characteristics.

Flame Fusion Method

The Flame Fusion method was the first successful process for producing synthetic corundum. During production, manufacturers melt aluminum oxide with chromium at extremely high temperatures. The molten material cools rapidly and forms ruby crystals within a few hours.

This process creates gemstones with excellent clarity and a bright appearance. However, the rapid growth often produces tiny gas bubbles and fewer inclusions than those found in natural rubies.

Flux Growth Method

The Flux Growth method requires significantly more time and may take up to six months to complete. During this process, manufacturers place the minerals into a molten chemical solution called flux. They carefully control the temperature and pressure so the crystals grow slowly.

As a result, Flux-grown rubies closely resemble natural rubies. They develop straight growth patterns and display characteristics that are similar to naturally formed gemstones.
