Alexandra Van Dell, (617) 335-2863

This simple yet stunning necklace comes in 18-karat white gold with diamonds and 4 mm pearls. Like all Van Dell pieces, this necklace is versatile, working well alone or with any of the designer's mix-and-match bails and pendants (which also hook onto her specially designed stud earrings) to create a nighttime-appropriate look.

Suggested retail price is $1,250.

Chanel, (800) 550-0005

Chanel launched the first J12 Tourbillon watch in white and black ceramic in 2000. The brand's first sports watch became an instant icon, appearing on a who's who of Hollywood starlets and spawning dozens of imitations. The company offered the piece in all-white ceramic a few years later. The latest take on the new classic, which comes in 18-karat white gold and black ceramic with 568 baguette-cut rubies, is chic and sophisticated. Of course, I'd expect nothing less from Chanel.
