New York gets dressy around the holidays, especially its store windows, where retailers light up the avenues with over-the-top displays. For those who like their holidays with more personal glitter, the annual December jewelry auctions are a highly anticipated New York tradition.

Provenance always plays a big role in collections offered at the year-end auctions; this year includes jewelry from Princess Natalie Paley, Nenetta Burton Carter (Amon Carter Museum), Judith-Ann Corrente, Susan Soros Weber, and the Rothschild banking family. If you like color in your diamonds, exceptional blues, pinks, yellows, and reds—the rarest of all the colored diamonds—make star appearances. So do the important jewelers, from Belperron to Van Cleef & Arpels to Taffin. Gents, too, will find jewels a-plenty.
