Van Cleef & Arpels Fleur Motif diamond necklace, available at select Birks boutiques; $81,960; www.birks.com
Roughly the price of a Porsche 911-though presumably more likely to impress a loved one-these three strands of Van Cleef & Arpels' subtle diamond flower motif may be the most expedient way to blow a bonus. Why Van Cleef? Because, in the 101 years since the French jeweller opened its first shop at 22 Place Vendôme (where it remains today), Van Cleef has embellished such figures as Marlene Dietrich, Grace Kelly and, most recently, Mariah Carey. Surely, 8.1 carats of diamond should be exquisite enough to satiate the diva in anyone.
