Lab Created Ruby / Synthetic Ruby / Synthetic Corundum
Premium Lab Created Ruby
Lab Created Ruby, also known as Synthetic Ruby or Synthetic Corundum, is a high-quality laboratory-grown gemstone that offers the same chemical composition and crystal structure as natural ruby. Created from Aluminum Oxide (Al₂O₃) with chromium as the coloring element, it displays a vibrant pink to deep blood-red color, outstanding brilliance, and exceptional durability.
Natural rubies have been treasured for centuries because of their beauty and rarity. Today, Lab Created Ruby provides the same striking appearance and excellent physical properties at a significantly lower cost. Therefore, it is an ideal choice for jewelry manufacturers, designers, wholesalers, retailers, and gemstone collectors.
History of Ruby
Ruby has been one of the world’s most admired gemstones for thousands of years. In ancient civilizations, rubies were often considered even more valuable than diamonds. According to Chinese legend, Emperor Kublai Khan once offered an entire city in exchange for a single ruby.
Ruby has traditionally symbolized courage, passion, strength, and prosperity. Many cultures believed it enhanced awareness, improved concentration, and inspired confidence. Today, ruby continues to be valued for both its beauty and its practical applications in science and technology.
How Is Lab Created Ruby Made?
Lab Created Ruby is manufactured using advanced crystal-growing methods that reproduce the natural formation of corundum.
Flame Fusion Process
The Flame Fusion Process was the first commercially successful method for producing synthetic corundum. In this process, aluminum oxide and chromium are melted at extremely high temperatures to form ruby crystals.
This manufacturing method produces gemstones quickly with excellent color and clarity. However, Flame Fusion rubies may contain tiny gas bubbles because of their rapid crystal growth.
Flux Growth Process
The Flux Growth Process is a slower crystal-growing technique that can take several months to complete.
During this process, aluminum oxide and chromium dissolve in a molten chemical solution called flux. The ruby crystals gradually grow under carefully controlled temperatures and pressure. Consequently, Flux-grown rubies develop crystal structures and growth patterns that closely resemble natural ruby.
