A rare and striking investment grade 20.07 carat "Royal Blue" No Heat Burma Sapphire takes center stage in this elegant 18K white gold ring, flanked by 2 half moon cut diamond and accented by a round cut diamond hidden halo.

From the fabled depths of Burma.

This gemstone is a masterpiece. A unique mix of a Star Sapphire and a regular Sapphire. Most Star Sapphires need to be opaque in order to see the star effect, but this Gem bears mesmerizing star effects on the edges while still having incredible transparency, so you can see the galaxy of rich blue color that's deep inside the stone. Set with an open back setting and a vividly saturated blue hue that penetrates the entire gem with even distribution and excellent luster.
