18K Black & White Diamond Cocktail Ring

Sale price$1,400.00

Three ribbons of diamonds—one white, two black—appear to cross paths around the finger in an asymmetric wave. The design reads as both architectural and organic, with each section of pavé diamonds bordered by precise milgrain work that adds an extra dose of texture to catch the light. At 6.48 grams, the ring has weight to it, the kind you notice when gesturing across a ballroom or holding a champagne flute. There's something unexpectedly versatile about the contrast: sharp enough for a fitted suit, elegant enough for evening wear, with a particular balance between masculine and feminine that makes it work on anyone who appreciates its deliberate design. The French workshop behind the piece left their mark—"Sté P" stamped in a lozenge alongside the 750 gold purity—though their identity remains unknown, which somehow suits a ring that refuses easy categorization.

The ring equivalent of always having a tuxedo pressed.

  • METAL: 18k white gold
  • WEIGHT: 6.48 grams
  • SIZE: 7.75 US (TD 56)
  • RESIZING: Cannot be resized due to continuous pavé setting
  • DESIGN: Single band with asymmetric wave creating three-ribbon effect, milgrain borders throughout
  • HALLMARKS: 750 and "Sté P" in lozenge-shaped cartouche

Stone Science
  • BLACK DIAMONDS: 57 larger stones (1.25-1.75mm each)
  • WHITE DIAMONDS: 24 stones (approximately 1mm each)
  • SETTING: Pavé-set with shared prongs
  • ESTIMATED WEIGHT: Approximately 0.75-1.0ctw combined
  • TREATMENT: Black diamonds likely heat-treated (industry standard)
  • DECORATIVE DETAIL: Milgrain borders between all diamond sections

Note: With 57 black diamonds at 1.25-1.75mm and 24 white diamonds at 1mm, the total carat weight estimate of 0.75-1.0ctw is based on standard diamond weight calculations for rounds of these sizes.

Era & History
  • ERA: Late 20th century to contemporary (post-1970s probable)
  • ORIGIN: European workshop (likely French based on lozenge format)
  • MAKER: Unidentified "Société P" - workshop mark not traced
  • CONDITION: Minimal wear, all stones secure, milgrain detail crisp
  • NOTABLE: No rhodium plating wear visible
Condition Notes

The ring shows minimal wear consistent with gentle use. All diamonds remain secure in their settings. The asymmetric design maintains proper form with no distortion. The milgrain detail remains crisp and well-defined.

Resizing Assessment: This ring CANNOT be resized due to the continuous pavé diamond setting around the entire band and the asymmetric design that would be compromised by sizing adjustments. Size TD 56 (US 7.75) only.
