These elegant gemstone stud earrings feature a trio of diamonds (.03 cttw) surmounting a faceted oval of icy pale blue aquamarine. The settings, posts, and friction backs are made from 10 karat yellow gold. Cool, sophisticated aquamarine displays a subtle hue that will complement other colors without overshadowing them. This pretty gemstone was once believed to originate from the treasure troves of mermaids, and was used as a talisman by sailors, who believed it would grant them safe passage at sea. Aquamarine is the birthstone for those born in March.
