Why This Piece

The David Yurman Lexington Black Onyx & Diamond Necklace combines several desirable luxury elements in one refined design: solid 18K yellow gold, faceted Black Onyx, pavé diamonds, and an adjustable textured gold chain.

The elongated 18 × 6mm Black Onyx creates a sleek architectural focal point, while the deep black gemstone contrasts sharply with the warmth of the solid yellow gold setting.

Approximately 0.16 TCW of pavé diamonds adds subtle brilliance without overpowering the clean, sophisticated silhouette.

The 2.4mm textured cable rolo chain, also crafted in solid 18K yellow gold, gives the necklace added substance and reinforces its fine-jewelry character.

Its combination of solid-gold construction, distinctive gemstone shape, diamond detailing, adjustable length, excellent condition, and very rare availability makes it especially appealing to collectors of David Yurman jewelry.

Why and How This Piece Is Authentic

This David Yurman Lexington Black Onyx & Diamond Necklace is professionally inspected as part of AYW Luxury's authentication process.

Authentication includes examination of the necklace's David Yurman hallmarks, 18K gold markings, Black Onyx setting, pavé diamond work, Lexington design characteristics, chain construction, lobster clasp, dimensions, proportions, finishing, and overall craftsmanship against known characteristics of authentic David Yurman jewelry.

Particular attention is given to the elongated gemstone proportions, pavé-setting quality, hallmark execution, chain texture, clasp construction, symmetry, and gold finishing.

Authenticity is determined by evaluating the hallmarks, materials, gemstone, diamond settings, chain construction, dimensions, hardware, 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.

Collector Note

David Yurman’s Lexington collection is known for refined architectural forms, polished proportions, and elevated precious-metal construction.

This example is especially distinctive for its faceted cylinder-shaped Black Onyx, a less conventional gemstone silhouette that gives the necklace a sleek and contemporary profile.

The solid 18K yellow gold construction, 0.16 TCW pavé diamond detailing, and 2.4mm textured cable rolo chain elevate the piece beyond a simple gemstone pendant.

Its excellent condition, original David Yurman pouch, adjustable 15–17-inch length, and very rare Lexington configuration make it a strong collector piece.
