Description

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 made from Aluminum Oxide (Al₂O₃) with chromium as the coloring element. It displays a vibrant pink to deep blood-red color, excellent brilliance, and exceptional durability. Therefore, it offers the beauty and performance of natural ruby at a much more affordable price.

For centuries, ruby has symbolized passion, courage, and strength. According to historical accounts, rubies were once considered more valuable than diamonds. Today, both natural and Lab Created Ruby are prized for jewelry as well as industrial applications, including watchmaking, medical instruments, and laser technology.

Manufacturing Process

Manufacturers produce Lab Created Ruby using two proven crystal growth methods.

First, the Flame Fusion Process combines high-purity aluminum oxide with chromium at extremely high temperatures. This method creates ruby crystals with brilliant color and excellent clarity. However, the rapid growth may produce tiny gas bubbles.

Next, the Flux Growth Process allows crystals to develop slowly in a molten chemical solution called flux. As a result, the crystals form natural-looking growth patterns that closely resemble those of natural ruby. Consequently, Flux-grown rubies are highly valued for their appearance.
