Each earring comes with a stud ( front ) and a earring stopper attached to a dangle or jacket ( back ). This style gives a "behind the ear" dangle rather than a busy dangle in front of the ear, giving a two dimension effect. The ear stud can also be worn without the back dangle.
Earring stud: Stainless steel
Ruby zoisite( dark green with black patterns) and malachite ( dark green ) gemstone beads.
Measurements: See last picture.
