Add a touch of elegance to your outfit with these stunning 14k / 585 yellow gold stud earrings. The oval blue topaz stones are securely set in a prong style, ensuring their sparkle and shine. The blue is more like a rich London blue color.  The "585" stamp indicating 14kt gold is on the post of the earring.  The backing has a plastic piece to it which has slightly yellowed over time, but I believe can be removed if you wish. The maker's stamp is also there on the post, but I am unfamiliar with it.
