Lab Grown Sapphires

Identical in physical, chemical, and optical properties to traditional sapphires, our selection of beautifully created sapphires emit a radiant and deep blue hue. Sapphires are a part of the corundum family. The name “sapphire” can apply to any corundum that isn’t red enough to qualify as a ruby. However, most classic sapphires are pure blue, ranging from greenish to violetish blue.

The corundum species also includes a scarcer form of sapphires known as “fancy sapphires,” which come in various colors, including violet, green, yellow, orange, pink, and purple. In addition, “parti-colored” sapphires are also in the corundum family, and they exhibit different combinations of colors. Some stones can even change colors depending on the lighting, while certain sapphires can boast a duller gray, black, or brown color.

Lab-grown sapphires can be manufactured through several processes. Many of these stones are made through flame fusion, which involves dropping powdered chemicals through a hot flame, allowing them to melt onto a rotating pedestal and create a crystal. The flux-growth process is another popular method for creating lab-grown sapphires, and it often makes a convincing alternative to the natural gem. However, this process requires a significant amount of time and financial investment. Flux is a solid material that dissolves other materials when it melts. Once the dissolved chemical solutions gradually cools, crystals begin to form.
