Synthetic Corundum Gemstones

Faceted oval gemstones cut from synthetic corundum. Pure corundum, aluminum oxide, is colorless, but small amounts of chemical impurities create myriad hues. The red variety of gem quality corundum has a specific name: ruby. All other gem corundums are termed sapphire. Massive, non-gem corundum is used as an abrasive. Corundum is produced synthetically in the laboratory by a variety of methods. The synthetic (man-made) material has optical and other properties nearly identical to natural corundum.
