The Lydia collection gives a sense of class and elegance to any outfit for a night out on the town or a simple dinner at a fancy restaurant. Each earring set has a clear stone crystal accent to help elevate the NCAA logo. All items are made from zinc alloy and are sealed with an anti-tarnish coating. Each piece is designed and assembled by working moms and grandmothers at our production office just outside Tulsa, Oklahoma. Some components are Made in China then assembled proudly in the USA.
