(You save )

This crescent moon, pierced by a dagger, has an enormous amount of sparkle and fire. Circa 1940/late Art Deco, Originally a tie pin, it's the latest addition to our new collection: Mix and Don't Match, Single Studs.

Add a bit of edgy chic to your jewelry wardrobe with this diamond dagger. Finely crafted in 18 Kt white gold (you can always tell by looking at the reverse side of a piece), it is set with approximately 1/4 carats of diamonds.

The Collection

We've paired the craftsmanship and quality of antique and vintage jewelry with a modern approach to styling in creating this collection. Individually chosen, each antique or vintage stickpin or brooch has been converted to an earring stud. Most are 14 kt gold, 18 kt gold, or platinum with precious gems and all are set with posts in matching gold/platinum purity. The attention to detail and one-of-a-kind design are not likely to be found in modern alternatives.

How it Works

Buy ONE - as a second earring to pair with your every day set of diamond or pearl studs, buy TWO - create your own set of bespoke earrings (one for each ear), MULTIPLE - create an earring stack.

Choose something with a symbol that means something to you (horseshoe for luck) or just because it is simply stunning. It's also a great way to add just a touch of edge or whimsy to your jewelry collection - e.g. mythical beast/Griffin. Check back to see what we add next!
