Natural white sapphires contain trace amounts of chromium oxide, while laboratory-created white sapphires do not. Although they are clear in color, white sapphires generally have a hazy white tinge that distinguishes them from diamonds, topaz, and moissanite. Natural and lab-created white sapphires are the two major forms of white sapphires used in jewelry. The first laboratory-created sapphire was produced in 1963 by two scientists at the Hughes Research Laboratories in California. As well, it is not possible to make artificial sapphires with larger sizes or higher prices since the technology doesn't allow for variations in color or quality. These processes can be used to make white sapphires but they cannot create colored varieties such as pink, blue, or green. They then use special techniques to grow thin layers of those chemicals on the surface of the gemstone. Instead, scientists create synthetic sapphires by melting silica (a chemical compound found in sand) with different chemicals to produce various colors. But creating sapphires in a laboratory without using this process or any other method of synthesis (the production of new materials) is impossible. In nature, sapphires are formed when carbon dioxide gas bubbles trapped within molten rock release their tension and collapse, forming tiny glass particles that accumulate to form gem-quality stones. It's called "created" rather than "manufactured" because it was created using the same processes that natural sapphires go through to form geode gems. White sapphire made in a lab is chemically and visually similar to white sapphire mined from the earth. What exactly does "Created White Sapphire" imply? The phrase "created" refers to a man-made gemstone that was developed in a laboratory environment.
