Professional Authentication & Independent Luxury Jewelry Verification
At AYW Luxury, every piece of pre-owned designer jewelry is professionally inspected and evaluated for authenticity before being offered for sale.
AYW Luxury is an independent retailer of pre-owned designer jewelry and is not affiliated with, authorized by, sponsored by, or endorsed by the brands represented on our website unless specifically stated otherwise.
Brand owners do not participate in AYW Luxury’s authentication, valuation, purchasing, consignment, or sales processes. Authentication is performed independently by AYW Luxury using multiple characteristics of the complete piece.
How AYW Luxury Authenticates Designer Jewelry
Authentication is not based on a single hallmark, stamp, photograph, or identifying feature.
Depending on the brand and item, our review may include:
Brand hallmarks and maker’s marks
Precious-metal purity markings
Materials and metal composition
Gemstones and diamond characteristics
Construction and craftsmanship
Weight, proportions, and dimensions
Clasps, hinges, hardware, and functional components
Engraving style and placement
Gemstone settings
Condition and signs of alteration
Collection-specific design details
Consistency with known examples from the designer
The characteristics considered can vary depending on the jewelry brand, collection, production period, materials, and design.
If a piece does not meet AYW Luxury’s authentication standards, it is not offered for sale.
Independent David Yurman Authentication
David Yurman jewelry is the primary specialty of AYW Luxury.
Our inventory may include Cable bracelets, Albion rings, Renaissance jewelry, Chatelaine designs, gemstone pieces, diamond jewelry, necklaces, pendants, earrings, men’s jewelry, sterling silver, 18K gold, mixed-metal designs, and rare retired collections.
Because David Yurman jewelry has been produced across many collections, materials, gemstone combinations, and production periods, identifying characteristics can vary from piece to piece.
Our review may consider features such as:
David Yurman hallmarks
Metal purity markings
Cable construction
Collection-specific proportions
Gemstone settings
Clasps and hardware
Engraving style
Weight and dimensions
Mixed-metal construction
Design characteristics associated with the collection
Authentication considers the complete piece rather than relying solely on the presence of a David Yurman stamp.

Authentication of Other Designer Jewelry
In addition to David Yurman, AYW Luxury offers select authenticated pieces from brands including John Hardy, LAGOS, Konstantino, and other established designer jewelry houses.
Each brand requires its own evaluation criteria.
For example, our review may consider:
Signature construction methods
Brand-specific hallmarks
Precious-metal markings
Collection characteristics
Chain or bracelet construction
Gemstone presentation
Design proportions
Known manufacturing details
Hardware and clasp construction
Because designer jewelry changes over time, authentication should always consider the characteristics of the individual piece and its likely production period.

Authentication is only one part of the evaluation process.
Every item is also reviewed for condition and accurate representation.
Depending on the piece, we may examine:
Surface wear
Scratches or polishing
Structural integrity
Prongs and gemstone security
Clasps and hinges
Repairs
Alterations
Replacement components when identifiable
Overall presentation
Relevant condition information is included in the product listing so buyers can better understand the jewelry before purchasing.

Depending on the item, documentation may include:

Gemstones

Documentation formats and included information may vary depending on the individual piece.
Our Authenticity Guarantee
AYW Luxury stands behind the authenticity and accurate representation of the jewelry we sell.
If an item sold by AYW Luxury is determined not to be authentic, it is covered by our authenticity guarantee and the applicable refund terms associated with the purchase.
Our objective is to provide buyers with clear product information and greater confidence when purchasing pre-owned designer jewelry online.
Why Independent Authentication Matters
The pre-owned jewelry market includes many different selling models, including individual sellers, marketplaces, consignment businesses, and specialist retailers.
The level of inspection and authentication provided can vary considerably.
AYW Luxury physically reviews the jewelry before it is listed for sale. This allows us to evaluate the individual piece rather than relying exclusively on information supplied by a previous owner or seller.
Professional review can be particularly important when purchasing:
Rare designer jewelry
Retired collections
Discontinued designs
Earlier production pieces
Unusual gemstone combinations
High-value jewelry
Pieces without original packaging or paperwork
Rare, Retired & Discontinued Jewelry
Older or discontinued jewelry may differ from current-production pieces in hallmarks, dimensions, materials, clasps, gemstone combinations, and construction details.
These differences do not automatically indicate that a piece is inauthentic.
Authentication of earlier designs may require comparison with characteristics associated with the relevant collection and production period.
AYW Luxury regularly works with rare and retired David Yurman jewelry and other hard-to-find designer pieces.
