Seven days in the week.

Seven diamond fringes.

We like where this is going.

This playful 14K yellow and white gold necklace features seven sparkling fringe drops set with a total of 70 natural round brilliant cut diamonds weighing approximately 1.00 carat.

The diamonds are bright G/H color and VS1/VS2 clarity, giving the necklace plenty of sparkle while the two-tone gold keeps it chic, easy and wonderfully wearable.

Finished with an 18-inch box-style chain and lobster claw clasp.

One fringe for Monday.
One for Tuesday.
And by Friday... perhaps all seven are working overtime.

Available from Watson & Son.

A little shell game we’re perfectly happy to play.

These wonderful 18K yellow gold cuff links are fashioned as hand-engraved clam shells, complete with limpet shell toggle backs.

The engraving gives each shell beautiful texture and definition, while the playful backs make them just as interesting from behind.

They’re nautical without being costume-y, elegant without being stuffy, and just quirky enough to start a conversation.

Shoot your cuffs with these marvelous mollusks.
