David Yurman Large Half Moon Renaissance Pendant

Authenticity Guarantee at AYW Luxury

At AYW Luxury, we specialize in offering the finest authentic pre-owned designer jewelry. Our unwavering commitment to genuine luxury pieces ensures that every item you purchase is 100% verified authentic, thoroughly evaluated by professional appraisers and jewelry experts.

How We Authenticate

Each piece of pre-owned designer jewelry undergoes a rigorous multi-step authentication process:

1. Multi-Point Visual Inspection

Our process begins with a comprehensive visual inspection. Our team examines each piece under magnification, checking for:

• Hallmarks and brand stamps (e.g., "DY 925," "14K," "750")
• Design consistency with known collections and model numbers
• Quality of construction — authentic designer jewelry is cleanly cast, precisely finished, and consistent in weight

We compare each item against a database of authentic reference pieces, looking for even the subtlest deviations.

2. Metal Verification

Next, we test the metal content to confirm the karat or alloy used:

• Sterling silver is verified to be .925 purity using XRF (X-ray fluorescence) or acid testing.
• Gold and platinum are tested for karat accuracy and hallmark matching.

This ensures your item is not only labeled correctly, but crafted from genuine fine metals.

3. Gemstone Evaluation

Gemstones are checked for:

• Authenticity (natural vs. synthetic vs. glass)
• Cut, color, clarity, and match with the original brand standards
• Proper setting technique — authentic brands use high-quality craftsmanship to set stones securely and symmetrically

For higher-value or rare gemstones, we may work with a third-party gemologist to ensure accuracy.

4. Collection & Design Match

Each piece is cross-referenced with the brand’s original catalog or verified archives. For example:

• Is this David Yurman Albion ring the correct size and proportion?
• Does the stone match what was offered in that collection year?
• Are cable bracelets shaped and soldered like authentic models?

This ensures we never list reproductions, replicas, or pieces “inspired by” designer brands.

5. Weight and Dimensions Comparison

Pre-owned designer pieces are weighed and measured against authentic standards. Most luxury brands are incredibly consistent in:

• Ring shank thickness
• Pendant dimensions
• Bangle or cuff weight

Any significant deviation is a red flag — and our team knows what to look for.

6. Provenance Review (When Available)

If a piece comes with its original box, pouch, receipt, or certificate, we carefully review them for consistency. While we don’t rely solely on documentation, these items can strengthen our confidence in authenticity.

7. Final Approval and Certification

Once all tests and checks are complete, the item undergoes a final review by our lead authenticator. Only after passing every checkpoint is the piece listed on our website as Certified Authentic.

Each item is then issued a digital or printed AYW Luxury certificate of authenticity upon request.
