Princess-cut yellow diamonds are set in polished 14 karat yellow gold to create these striking stud earrings. The small square diamonds have been treated and enhanced to bring out their intense, yellow-green color. They have a fair cut and a total weight of 3/8 carat. The diamonds are held securely in four-prong settings and featured on 14 karat yellow gold posts with friction back closures. Natural yellow diamonds are extremely rare, but special methods of irradiating and heat treating the stones have allowed the production of intensely colored diamonds in a variety of shades, including yellow. Treated yellow diamonds are more durable than other yellow gemstones such as citrine and topaz, and they have their own distinctive look, with a vibrant hue and a telltale diamond sparkle.
