Lab Grown Pulled Czochralski Blue Sapphire Loose Lab Royal Blue Sapphire Gemstone wholesale from china Suppliers and Manufacturer.
What's Pulled Czochralski Blue Sapphire Gemstone?
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.
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.
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. It is better to buy synthetic Blue Sapphire made by Pulled method as they have exact same chemical composition and physical composition and are sold at fraction of price of natural Blue Sapphire. They also appear brighter and more vivid than natural Blue Sapphire making it the better than corundum blue sapphire stones.
SYNTHETIC Blue Sapphire (Pulled Czochralski) PROPERTIES：
Chemical Formula:Al2O3
Hardness: 9
Luster-Subadamantine To Vitreous
Stability:Very Good
Fracture:Conchoidal
Refractive Index:1.762-1.77
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.
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.
