FREQUENTLY ASKED QUESTIONS What is 14k Gold-Filled? Gold-filled is the next best option to 14k solid gold. It is a less expensive option and it is hypoallergenic. Gold-filled is actual 14k gold heat-bonded with an inner core of brass as opposed to gold plated which is a thin layer of gold liquid solution electroplated over a base metal. Brass is used because it is hypoallergenic. All our clasps and ear wires will be marked 14/20 GF. We do offer a few components in gold plating but in a higher quality long lasting micron option. Are your gemstones and pearls real? Yes, they are genuine stones and pearls. Because they are real, some may have natural inclusions. They are all one-of-a-kind and we do our best to pick the most beautiful ones for your order and discard any that aren't up to our standards.
