Violette CoCo Chanel Necklace. A handful of wild plums just before they're ripe — sun-warm from the orchard. This Violette CoCo necklace is a repurposed Chanel silver chain with a blond pale gold pendant and multiple small natural agate gemstones in shifting plum shades. Close your eyes: it's 4pm in July, you're barefoot on a porch, someone just handed you a cold glass of something purple. That's the feeling Violette clips around your neck.
