It is used as the stone for the 4th Anniversary. It is known as one of the first gemstone used by man. Ancient travelers wore the gemstone to protect them from plagues and injury. It is also believed to increase appetite and relieve pain.
Blue Zircon has a lively, natural light to medium slightly greenish-blue color with brilliance that rivals a diamond. I think is makes a great eternity band when paired with diamonds to commemorate the birth of a December child.
I also like to pair it with blue sapphires as well as brown zircons. It looks great set in both yellow gold and white gold, or silver. The gem is readily available in a variety of sizes, I prefer the round shape to maximize its refraction and dispersion!
