You’re never fully dressed without a smile — or a good pair of cufflinks. Helping with both of those finishing touches is the March 18 Fine Jewels sale at Sotheby’s London. Twelve of the auction’s 284 lots delight with jeweled cufflinks from Boucheron, Bulgari, and more. Twinkling with rubies and emeralds, diamonds and sapphires, the accessories alternately come in gorgeous groupings or as a standalone — and standout — pair. For buyers not in need of fasteners, Fine Jewels offers a tantalizing variety of pieces from the 18th century to the present day. All will be on view at Sotheby’s London from March 13 through March 17.
