This gorgeous locket was x-rayed by a jeweler and confirmed to be 15k gold with an 18k or higher gold overlay. Let me reiterate again that this is a solid gold piece with high karat gold over more high karat gold (not gold plated or gold filled). It has gained an exceptionally beautiful patina during the 150-160 years it has spent on this earth. It has a tightly fitting snap closure (which makes a super satisfying sound) and houses two photos, one of a man and one of three children. The glass is in excellent condition. It weighs 12.8g and measures 3.4cm tall without the bail x 2.5cm wide. With the bail, it measures 4.2cm tall. It features 6 2mm sized pearls and 4 1mm sized pearls with beautiful luster and uniform color. It is a wonderful example of the Etruscan revival style in Victorian Jewelry.
