Jacquie Aiche Moonstone and Diamond Choker

Jacquie Aiche Moonstone and Diamond Choker, $1125, jacquieaiche.com.

The choker can be a tricky accessory to pull off, teetering, on occasion, between too goth and too trendy. But by adding luxe details like moonstones and diamonds to a chic black cord, Jacquie Aiche has created a version that’s just right. And, since Kristen Stewart wore one on “The Tonight Show Starring Jimmy Fallon” earlier this week, it’s now celebrity-approved, too.
