What's Pulled Czochralski Blue Sapphire Gemstone?
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. Flame fusion creates long, tear-shaped pieces of synthetic corundum. Consisting of a mix of aluminum oxide and chromium, would have yielded a synthetic ruby.
As It follows the same process as natural Blue Sapphire is created make it the most superior among other Blue Sapphire. Natural Blue Sapphire are rare and over-valued.

How Can Gemologists Distinguish Lab-Grown Sapphires From Natural Sapphires?
Distinguishing lab-grown sapphires from natural sapphires is challenging, but each artificial creation method leaves telltale signs that an expert gemologist can identify.
Melt processes like flame fusion may create sapphires that exhibit curved growth lines and curved color bands not found in nature. The Czochralski process also may produce gems with inclusions like gas bubbles and smoky veils. Hydrothermal synthesis may leave distinctive “nail head” inclusions.
