Authenticating Pre-Owned Designer Jewelry

Authenticity is an important consideration when purchasing pre-owned designer jewelry on the secondary market.

Depending on the designer, jewelry type, and collection, authentic pieces may feature recognizable hallmarks, designer signatures, precious-metal purity markings, distinctive construction techniques, signature Cable patterns, gemstone settings, clasps, engravings, proportions, and collection-specific design details.

From David Yurman, John Hardy, and LAGOS to other luxury jewelry designers, authentication characteristics can vary across rings, bracelets, necklaces, pendants, earrings, and other fine jewelry.

Because markings, materials, and construction can differ by brand, collection, and production period, authentication should evaluate the complete piece rather than relying on a single stamp or identifying feature.

At AYW Luxury, every piece of designer jewelry is professionally evaluated using multiple characteristics before being offered for sale as Certified Pre-Owned.
