This process is actually similar to how lab created diamonds are made. Under those intense conditions, the pressure forces the seed to create sapphire crystals as the mineral solution starts rising. They actually place a tiny seed crystal from a natural sapphire into said chamber. But instead of being deep beneath the earth under pressure and high temperatures, they are put in their own little chamber full of heat and pressure. This process imitates the natural way sapphires form.
The solution process is also called hydrothermal synthesis. To create other color varieties of corundum, they add other minerals to it. The melted powder forms into a long teardrop shape referred to as a boule.
Aluminum oxide is the main mineral within corundum. It is the very first process they came up with and the most inexpensive.ĭuring flame fusion, aluminum oxide powder is melted by means of a flame. In the melting process, they do what's called flame fusion. Sapphires have two ways of being synthesized: melting and solution. Sapphires and rubies were actually some of the first gemstones to by synthesized, or lab-grown. Natural white sapphire is very rare, so it's safe to assume that all white sapphire jewelry seen in stores and online will be lab-created by gemologists. White sapphire is the name for colorless corundum. Sapphires actually come in every color of the rainbow, however, there's no such thing as a red sapphire.
