About Lab Created Ruby

Lab Created Ruby is a synthetic variety of Corundum (Al₂O₃) that displays a beautiful pink to deep blood-red color. It offers exceptional brilliance, outstanding hardness, and excellent durability. As a result, it is a popular choice for fine 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 rich red color symbolized the power of the sun. Some legends even claimed that placing a ruby in water would cause the water to boil.

Today, Lab Created Ruby is widely used in watches, medical instruments, precision equipment, and laser technology because of its excellent optical and physical properties.

Unusual Properties

Lab Created Ruby is known for its intense brilliance and remarkable durability. Many people associate ruby with confidence, courage, focus, and mental clarity. In addition, its exceptional hardness makes it suitable for everyday jewelry.

Besides its beauty, synthetic ruby plays an important role in modern technology. Manufacturers use it in watchmaking, medical instruments, scientific equipment, and surgical lasers because of its reliable optical performance.

Treatment and Manufacturing

Manufacturers create Lab Created Rubies using two primary production methods. Both methods combine aluminum oxide with chromium to produce the vibrant red color that characterizes ruby.

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 material then cools and forms ruby crystals within a few hours.

This process creates gemstones with excellent clarity and a bright appearance. However, rapid crystal growth may produce tiny gas bubbles and fewer natural inclusions.

Flux Growth Method

The Flux Growth method requires significantly more time and may take up to six months. During this process, manufacturers place the minerals in 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 that are similar to naturally formed gemstones.

Jewelry Applications

Lab Created Rubies are perfect for a wide variety of jewelry, including:

• Rings
• Necklaces
• Earrings
• Bracelets
• Pendants
• Custom jewelry designs

Their brilliant color, outstanding hardness, and excellent durability make them suitable for both everyday wear and special occasions.
