These stunning earrings are crafted from platinum plated and yellow gold accented 925 sterling silver and feature premium, natural, rare Grandidierite gemstones. Platinum plating offers hardness and corrosion resistive properties to the metal. Yellow gold vermeil is a premium jewelry finish that only uses genuine gold. The coating of yellow gold is 2.5 microns thick. Platinum / yellow gold vermeil prevents tarnishing, increases the metal-life, and offers a shiny finish. The oval Grandidierite stones measure 4mm x 3mm in length and width, and are securely prong set in a setting of two-tone earrings hanging from sterling silver leverbacks. They are stamped 925 and signed. With a total carat weight of 1.15 ctw, these earrings make a beautiful addition to any fine jewelry collection.
