Super secure square shape that adds a lot of bang for your ear wire buck. Two strands of 24 gauge oxidized sterling silver equal the standard 20 gauge most used for ear wires. Oxidization, or patina, can be polished away a little or a lot in desired areas with a silver cloth- the "high points" are the easiest and most natural looking effect. The measurement from top to bottom loop is just under 1", though each pair is hand formed so minor variability in size happens. Also available in mini and large sizes in bright silver, gold and rose gold fill.
