GRS-Certified Blue Sapphire

Blue Sapphire Gemstone (Neelam Stone) is a highly precious crystal of the corundum mineral family. With a Mohs hardness of 9, this gem is widely used for both fashion and astrological purposes. However, several times these gems are heated and chemically treated to enhance color and clarity, which is not correct on the astrological ground. So if you are also planning to purchase this beautiful crystal, especially for astrological reasons, then ensure to buy a natural Neelam stone with no heat or chemical treatment. For the best assurance, you can buy GRS-Certified Blue Sapphire from a trusted gemstone website like Navratan. GRS is a prestigious gem testing lab that certifies the color, clarity, origin, and treatment of a stone.
