This process involves infusion of color giving materials on to the surface of a cut synthetic gemstone. However there is a notable difference when it comes to diffusion treated synthetic faceted sapphires. The only difference is the process that was involved to create them. The hardness score is 9 therefore even the lab created sapphires can withstand the tear and wear to the same extent as natural sapphire. Natural SapphireĪs long as the chemical and material composition is concerns both are the same. However the synthetics made of solution process has superior quality in terms of the evenness of corundum properties and color distribution. These two methods are quite expensive and take up to a year, may be more to produce the stones. Whereas hydrothermal method involves creating the natural crystal growing environments in a lab.

Notably two methods known as flux growth and hydrothermal growth.įlux growth involves dissolving the growth materials in a solution and cooling. Solution ProcessĪn advanced way of making the synthetics. The process and the materials used during the melt process allows it to be sold at a lower rate.

The sapphires or the corundum are grown in a matter of days with this method.
