This is a radiant cut, unheated blue sapphire. Similar to other gemstones in our collection, this exquisite sapphire has a good open hue of blue with excellent cutting. Clarity of the gemstone is also excellent, easily seen from the attached video.
An interesting point about this particular piece is regarding its cutting. Due to its larger facets, the table of the gemstone is much larger than similarly weighted sapphires. Much more bang for buck!
