Gold is chemically stable enough that it does not oxidize or corrode, which is precisely why the yellow color of 14kt gold requires no protective coating and does not fade with age.
A Storied Heritage
Pearl is the oldest gem material in human jewelry, with archaeological evidence of adornment dating to ancient Mesopotamia and the Persian Gulf. Natural pearls were harvested from oyster beds and traded across ancient networks as objects of extraordinary value. For a June birthstone gift with genuine historical depth, pearl's documented lineage is longer than any other gem material's.

Hold a high-nacre cultured pearl in direct light and move it slowly. The glow has depth rather than surface brightness. That quality comes from nacre being secreted in concentric layers around the nucleus, each layer adding to the reflective complexity that produces it.
