In some sites a small amount of iron in the corundum crystal produces a gem the color of sunshine, which is what you see in this alluring cushion shape stone. Yellow sapphires represent Jupiter in Vedic astrology, and like Jupiter, the gem bestows success and longevity on its wearer. Like the majority of superlative yellow sapphires, this Unheated Yellow Sapphire GIA certified stone is from Sri Lanka. Sapphires are prized not just for their beauty and fire, but for the hardness of the mineral. Next to diamond, it is the hardest stone on earth, resisting scratches and damage. This ray of sun will shine on your finger for a lifetime.
