The revolver clasp's solid barrel adds slightly more weight to a piece than a springring or lobster clasp would. The added heft at the closure contributes to an overall sense of quality.
Elemental Detail
Two-tone gold combines two gold alloy colors, most commonly yellow and white, within a single piece, using the contrast between them as a deliberate design element. This makes it compatible with a broader range of other jewelry in different metal tones.
Made With Purpose
The color in 14kt multitone gold doesn't appear by accident. Either separate alloy components are fabricated and assembled, or sheet metals of different alloy colors are bonded and rolled before forming. Both methods produce the creative result.
