Zircon ... a fabulous stone. An entirely natural gem (unlike zirconia), of an incredible color, a cyan blue reminiscent of the nuances of luminous skies, a shine of a thousand lights! If you want a beautiful stone, shiny like a diamond, with the most beautiful colors, turn to natural zircon, which will also offer you a very affordable choice.
