Genuine Natural Chalcedony Silver Earrings

I made these earrings with very special 100% genuine natural chalcedony. These chalcedony stones changes colors: sometimes milky white, sometime sky blue, sometimes in-between. The color changes back and force among these shades, and always look very beautiful. I top these mysterious stones with tiny teal blue quartz and mystic green quartz. All metal components are 925 sterling silver.
