Another melt process, the Czochralski process, uses radio waves to melt the aluminum oxide. A rod tipped with a seed crystal is inserted into the mixture and slowly rotated and pulled out, creating a column of sapphire. The lab created Blue Sapphire can also be created by flame fusion but the quality and resemblance of synthetic Blue Sapphire created by Czochralski Pulled process is considered to be the best and superior to all other lab created Blue Sapphire.
