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.
Lab Created Pulled Blue Sapphire looks exactly like natural Blue Sapphire. Only when observed under high magnification microscope in labs, small bubbles or foreign particles can only differentiate between them.
