Perfect for layering or understated looks, the elin triple gold ball necklace is simple and timeless. Made with 14K gold vermeil, this hypoallergenic piece is also safe to wear in water. Gold Vermeil: Gold Vermeil (pronounced ver-may), a sterling silver base with heavy and thicker gold plating (2.5 microns by US standards). It does not tarnish and it is hypoallergenic. Because gold vermeil is much thicker layer than gold plating, the gold last longer and will not rub off. However, the gold will gradually wear off overtime.
