Certification, Authenticity & Valuation

Certified Pre-Owned Authenticity Guarantee at AYW Luxury

At AYW Luxury, every piece of jewelry we offer is more than just pre-owned — it’s Certified Pre-Owned. Our strict certification process ensures that your purchase is authentic, accurately described, and fairly valued. From authentication to valuation and certification, our goal is to deliver not only fine jewelry but also complete peace of mind.


How We Authenticate

Each item undergoes a rigorous multi-step authentication process performed by trained specialists and jewelry experts with over 40 years of combined industry experience:

  1. Multi-Point Visual Inspection
    • Hallmarks, engravings, and brand stamps (e.g., “DY 925,” “750”)
    • Design consistency with known collections and catalog references
    • Precision craftsmanship, weight consistency, and finishing quality
  2. Metal Verification
    • Testing gold, platinum, and silver content using professional tools (XRF/acid testing)
    • Ensuring karat accuracy and hallmark alignment
  3. Gemstone Evaluation
    • Confirming gemstone authenticity (natural vs. synthetic)
    • Assessing cut, color, clarity, and secure setting
    • Consulting third-party gemologists for rare or high-value stones
  4. Collection & Design Match
    • Cross-checking each piece against brand archives and catalogs
    • Confirming correct proportions, stone offerings, and construction
  5. Weight & Dimension Comparison
    • Matching measurements against authentic brand standards for rings, bracelets, pendants, and earrings
  6. Provenance Review (When Available)
    • Verifying original packaging, receipts, or certificates for consistency
  7. Final Approval & Certification
    • Lead authenticators give the final review
    • Items that pass every checkpoint are officially listed as Certified Authentic


Professional Valuation

After authentication, every item is assigned a professional valuation. Each purchase comes with an Authenticity & Valuation Report that includes:

  • Verified brand and product name
  • Gemstone analysis (type, quality, carat weight)
  • Metal verification with karat and total weight
  • Condition grading (Excellent, Mint, Very Good, etc.)
  • Verified purchase price


Certification & Guarantee

Once certified, each piece is delivered with:

  • An AYW Luxury Authenticity & Valuation Report
  • A digital or printed Certificate of Authenticity upon request
  • High-resolution photos showcasing hallmarks, engravings, and craftsmanship details

Our Authenticity Guarantee means your jewelry is genuine, accurately represented, and fairly priced—or your money back.
