Why This Piece

The David Yurman Couture White Agate, Black Spinel & Black Diamond Necklace combines several exceptional design elements in one dramatic collector piece: oversized White Agate beads, contrasting Black Spinel, a pavé Black Diamond centerpiece, sterling silver construction, and substantial 20-inch proportions.

The approximately 20mm cabochon White Agate beads give the necklace exceptional scale and a clean, luminous appearance.

Smaller 4mm Black Spinel beads create strong visual contrast and define the spacing between the larger white gemstones.

At the center, the approximately 16mm pavé Black Diamond bead provides a dramatic focal point and adds sophisticated brilliance to the otherwise monochromatic palette.

The hidden push-twist clasp preserves the continuous appearance of the necklace while keeping the overall design polished and uninterrupted.

Its combination of oversized gemstone scale, black diamond detailing, Couture styling, excellent condition, and extreme rarity makes it especially appealing to serious collectors of David Yurman jewelry.

Why and How This Piece Is Authentic

This David Yurman Couture White Agate, Black Spinel & Black Diamond Necklace is professionally inspected as part of AYW Luxury's authentication process.

Authentication includes examination of the necklace's David Yurman hallmarks, sterling silver components, White Agate and Black Spinel bead proportions, pavé Black Diamond centerpiece, hidden clasp construction, dimensions, finishing, and overall craftsmanship against known characteristics of authentic David Yurman jewelry.

Particular attention is given to the pavé-setting quality of the centerpiece bead, consistency of the gemstone arrangement, hallmark execution, clasp mechanism, symmetry, proportions, and surface finishing.

Authenticity is determined by evaluating the hallmarks, materials, gemstones, diamond settings, construction, hardware, dimensions, finishing, and design characteristics collectively rather than relying on any single identifying feature.

Authenticity Guaranteed — 100% verified authentic.

Certified Pre-Owned — includes an Authenticity & Valuation Report.
