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

About Lab Created Ruby

Lab Created Ruby is a synthetic variety of Corundum (Al₂O₃) that displays a vibrant pink to deep blood-red color. It offers exceptional brilliance, outstanding durability, and a hardness of 9 on the Mohs scale. As a result, it is an excellent choice for fine jewelry and industrial applications.

In ancient times, rubies were often 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 increased awareness, improved concentration, and inspired courage. Furthermore, its rich red color symbolized the sun. Some legends even claimed that a ruby could make water boil when placed inside it.

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

Treatment

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

Flame Fusion Method

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

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

Flux Growth Method

The Flux Growth method requires 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 to encourage slow crystal growth.

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