Round Lab-Created Ruby Cabochon

Synthetic Ruby Gemstone

Composed of man-made corundum, this synthetic ruby has the same chemical composition, durability, and brilliance as natural ruby. It offers excellent clarity and vivid, even coloration at an accessible price.

Ruby, known in Sanskrit as the “King of Gems”, has been one of the most prized and valuable gemstones since ancient times. As the most valuable variety of corundum, ruby commands the highest per-carat price of any colored gemstone. Its rich red hue is due to trace amounts of chromium, with colors ranging from orangey red to purplish red. Pure, vivid red to slightly purplish red is the most highly valued.
