Blue Sapphire Gemstones in 5 carat size plus
AfricaGems.com has a impressive collection of larger, 5 carat sizes plus of loose blue sapphire gemstones.  Our collection includes natural unheated blue sapphires as well as heated blue sapphire gems.  These beautiful loose sapphires have origins from Sri Lanka, Madagascar and Thailand. Blue sapphire is a member of the corundum family of gemstones, and unlike ruby gemstones, has many different source locations. Blue sapphires from Burma Kashmir are the most highly sought after blue sapphires, followed by Ceylon blue sapphires and Madagascar sapphires.  The cornflower blue color of a high quality blue sapphire gem is the standard by which other blue sapphires are judged. Most sapphires of any color are heat treated, which is always noted on any sapphire AfricaGems.com sells. Fine quality sapphires with no heat treatment command the highest prices. Some sapphires have been altered with chemical diffusion; AfricaGems does not sell these sapphires. Many of our sapphire gemstones are accompanied by a third party certificate of appraisal and retail value. Many of these sapphires have been recut in the USA to American standards and cannot be compared to native cut gems. Our USA cut sapphire gemstones have unsurpassed brilliance and a much sharper "look".
AfricaGems has a vast and unique selection of spectacular Sapphire gemstone rings and Sapphire pendants.
