Lab Created Ruby / Synthetic Ruby / Synthetic Corundum
Premium Lab Created Ruby
Lab Created Ruby, also known as Synthetic Ruby or Synthetic Corundum, is a premium laboratory-grown gemstone with the same chemical composition as natural ruby. Made from Aluminum Oxide (Al₂O₃) and colored with chromium, it displays a vibrant pink to deep blood-red color, exceptional brilliance, and excellent durability.
Natural ruby has long been one of the world’s most treasured gemstones. However, Lab Created Ruby offers the same stunning appearance and outstanding physical properties at a more affordable price. Therefore, it is an excellent choice for jewelry manufacturers, designers, wholesalers, retailers, and gemstone collectors.
History and Significance of Ruby
Ruby has been admired for centuries because of its remarkable beauty and rich symbolism. In ancient times, many civilizations valued ruby even more than diamonds. According to Chinese legend, Emperor Kublai Khan once offered an entire city in exchange for a single ruby.
For generations, ruby has represented courage, wisdom, strength, and passion. Many cultures believed the gemstone improved awareness, increased concentration, and inspired confidence. Although these beliefs are traditional rather than scientific, they continue to add to ruby’s enduring appeal.
Today, both natural and Lab Created Ruby are valued not only for jewelry but also for advanced industrial and technological applications.
How Is Lab Created Ruby Manufactured?
Manufacturers produce Lab Created Ruby using advanced crystal-growing techniques that replicate the natural formation of corundum.
Flame Fusion Process
The Flame Fusion Process was the first commercial method used to manufacture synthetic corundum. During this process, manufacturers melt high-purity aluminum oxide with chromium at extremely high temperatures. The crystal forms quickly and develops a vibrant red color.
Because the crystal grows rapidly, Flame Fusion rubies usually have excellent clarity. However, they may contain tiny gas bubbles and fewer natural-looking inclusions.
Flux Growth Process
The Flux Growth Process produces premium-quality Synthetic Ruby over several months.
Manufacturers dissolve aluminum oxide and chromium inside a molten chemical mixture called flux. The ruby crystal then grows slowly under carefully controlled temperatures and pressure. As a result, Flux-grown rubies develop natural-looking growth patterns and characteristics that closely resemble natural ruby.
