Aqua Chalcedony and brushed sterling silver 'three little disc earrings. I love these earrings! They hang beautifully, are light and comfortable. Aqua Chalcedony is our best selling gemstone. The colour is pretty, fresh, works with all metals and suits all skin tones so it's a winner if you are thinking of a gift for someone. It's also a calming stone that protects you and keeps away negative energy. Sure what more would you want!
