Lab Created Dark Ruby / Synthetic Dark Ruby / Synthetic Corundum
Premium Lab Created Dark Ruby
Lab Created Dark Ruby, also known as Synthetic Dark Ruby, is a premium laboratory-grown gemstone in the Synthetic Corundum family. Manufactured using the Verneuil (Flame Fusion) Process, it offers the same chemical composition, hardness, and appearance as natural ruby while remaining a much more affordable option.
Natural dark ruby is rare and expensive, with high-quality stones often costing thousands of dollars per carat. Therefore, Lab Created Dark Ruby provides an excellent alternative for jewelry manufacturers, designers, and gemstone collectors who want the beauty of ruby at a lower cost.
Unlike standard synthetic rubies, our Synthetic Dark Ruby features carefully created inclusions that give the gemstone a more natural appearance. As a result, it closely resembles natural ruby while maintaining consistent quality and durability.
Manufacturing Process
Lab Created Dark Ruby is produced using the Verneuil (Flame Fusion) Process. During manufacturing, high-purity aluminum oxide is combined with chromium at extremely high temperatures to grow ruby crystals.
Consequently, the finished gemstone has the same chemical composition and nearly identical physical properties as natural ruby. It also offers excellent brilliance, durability, and long-lasting color.
