Outstanding heart shaped with A grade color blue Zircon gemstone. This natural blue Zircon from Cambodia is another collectible gem boasting some of the best possible and dense blue color. It is very well cut with no window, shining all over and with the best possible color. This blue color is so dense and blue that the dispersion on some photos give these incredible shades of green while in reality to the naked eye they are dense navy blue flashes. This is the best possible present of a heart-shaped pendant or even ring for an exquisite Valentine present or an engagement.
