Jewelry designers are known to specialize. For example, they may only use certain types of gemstones and metals. Or, they have may lean toward a particular sort of technique or jewelry style. But, jewelry designer Mary E. Pongonis has a unique specialization - earrings. She even has a patent for a certain type of ear wire design. Her company is called Meya2s, where the 2 is square, not a 2 right next to the other letters, and she sells finished earrings designs (pictured above is Beaded Amy A's) as well as just earring wires, which are unique wire designs in themselves. Here are some more earrings from the Amy A collection.
