14KT GOLD FILLED
Gold fill is a much more affordable alternative to Solid Gold. With a layer of solid 14kt gold pressure bonded to a brass base metal, gold-filled pieces can last for many years with proper care. This technique is more durable than gold plating, but to be clear it is not solid gold. Gold filled is generally safe for most sensitive skin types, but can cause a reaction if you are allergic to brass.
Although gold filled is very durable it can fade over time. Usually it can be cleaned by using a soft toothbrush combined with mild dish soap and water. It is still recommended to avoid contact with perfumes, lotions, ocean/pool water or any other harsh products.
