A stunning large Loose Blue Lab Sapphire. 4.25 carat Rich Blue sapphire, ‘Emerald’ cut. 8.6mm x 8.6mm Ref 142
The images show the process of cutting and polishing the Sapphire.
Lab-created gems are identical to those formed underground and mined. They’re “grown” in a lab under the same conditions of heat and pressure as a gem that forms underground yet have the advantage of having the ultimate colour & clarity.
It’s a great way to get a beautiful real gemstone at an affordable cost.
The stone has been precision cut and polished by me in the United Kingdom.
Sapphire is one of the rarest and most valuable precious gems.
Sapphire is a gemstone, a variety of the mineral corundum. It is typically blue in colour, but natural "fancy" sapphires also occur in yellow, purple, orange, and green colours; "parti sapphires" show two or more colours.
Sapphires have a hardness of 9.0 on the Mohs scale of mineral hardness. Among the natural gems only moissanite and diamond are harder, with diamond having a Mohs hardness of 10.0
Sapphire, the birthstone of September, is most desired in its pure, rich blue colour but is present in almost every colour including pink, yellow and green.
In the Middle Ages the gem was believed to protect those close to you from harm and also represented loyalty and trust.
