Carnelian and gold plate earrings. Carnelian is from the chalcedony quartz group.
According to Wikepedia, "Carnelian was recovered from Bronze Age Minoan layers at Knossos on Crete in a form that demonstrated its use in decorative arts; this use dates to approximately 1800 BC. Carnelian was used widely during Roman times to make engraved gems for signet or seal rings for imprinting a seal with wax on correspondence or other important documents. Great for casual, business and dressy styles! Perfect compliment to the "Sunset" necklace pictured below.
