On the inner surface of a 14kt piece (the shank of a ring, the back of a pendant) you will find a small stamped mark: '14K,' '14KT,' or the European '585,' each physically pressed into the metal to confirm its gold content.
Origin Story
Saltwater cultured pearl production requires one to three years inside the mollusk before harvest. The cultivation timeline directly affects nacre thickness, and nacre thickness directly determines the depth of luster the finished pearl displays.
Elemental Detail
The quintessential warm hue of 14kt yellow gold comes from silver and copper worked into the alloy at specific ratios alongside the gold itself.
