Inspired by ancient Roman jewelry, these earrings feature a Herculean knot with a translucent blue iolite dangle. The Herculean knot has often appeared in jewelry since the 4th century B.C. As an elaborate and most stable form of knot with two strands, it stands for the perfect union of two partners and could therefore symbolize a wedding. These earrings come complete with french wire backings. Measures 1.75 x .25 in.
