Signature Collections

Cluster Rings

1940s–present

The foundation of the Winston look. Unlike modern cluster rings that use commercial melee, 1940s-1960s Winston clusters use individually selected, high-color, high-clarity diamonds calibrated perfectly to the millimeter.

Wreath Brooch

1940s–1970s

A classic arrangement of marquise and pear-shape diamonds mimicking a holly wreath. These were favored by major collectors in the Taylor-Burton era and remain highly liquid at auction.

Winston Knot

1980s–present

An interlocking diamond or colored stone loop. While recognizable, the real value lies in the pre-1990s examples before production scaled up.

Art Deco Revival

1940s–1960s

Peak Winston craftsmanship. Large architectural center stones flanked by step-cut trapezoids and bullets. This is where Winston's cutting expertise shines.

Colored Stone Suites

1950s–1980s

Institutional-level jewelry. Winston routinely bought the finest Kashmir sapphires, Colombian emeralds, and Burma rubies on the market, setting them in minimal platinum to highlight the stone.

Authentication Guide

Hallmarks

  • ◆Marks vary by piece; ownership and inventory numbers are very useful when present, but are not a strict requirement on all vintage items.
  • ◆The 'HW' maker's mark or full 'Harry Winston' signature may have changed in style depending on the decade.

What to Look For

  • ✓Uncompromising stone quality is the primary hallmark; Winston pieces focus intensely on top-tier diamonds.
  • ✓Masterful, minimal metalwork designed to make the stones appear as if they are floating.

Red Flags

  • ✗Low-color, highly included, or heavily treated stones masquerading as Winston quality.
  • ✗Heavy, clumsy metalwork or thick prongs that overwhelm the stones.
  • ✗Missing structural integrity or use of base metals.

What Dealers Look For

1

Harry Winston experienced periods of quality inconsistency in the 1990s and 2000s; this is a fascinating part of documented history, not a reason to reject a piece.

2

Ownership numbers add wonderful provenance but aren't necessary for a piece to be genuinely Winston.

3

Let the stones do the talking—exceptional diamonds are the truest indicator of a Winston creation.
