This soutache earring uses a beautiful acrylic cabochon with golden motives as a focal stone that is wrapped up in black Swarovski crystal chain and black soutache thread. The stud is behind the square shaped Swarovski stone that is also covered with soutache thread. These two parts are sewn together with two Swarovski crystals.
The backing is genuine lambskin leather.
