1. Fred Leighton — Madison Avenue, Manhattan
The best-known estate jewelry house in New York, on Madison since 1984.
Fred Leighton began in Greenwich Village and moved uptown to Madison Avenue in 1984, becoming the name most associated with antique and estate jewelry in New York — and the one whose pieces turn up on red carpets.
The range covers Georgian through mid-century, with real depth in Art Deco and in signed pieces by the great houses, and the staff know the provenance of what they sell.
This is the top of the estate market rather than the bargain end, and it is priced that way, but it is also where the condition and the attributions can be trusted.
Good to know: Say what period you are interested in — a great deal of the stock is not on display.
