I've made these quartz gemstone earrings with teal quartz briolettes dangling from hoops I've handcrafted out of argentium sterling silver. These are swingy and full of sparkle, and the lovely teal color is great as we move into cooler weather.
Total earring length is approximately 1 3/4 inches (4.4 cm), and the circles are about 1/2 inch (1.2 cm) across. The quartz briolettes are about 9 mm x 6 mm.
