Certification, Authenticity & Valuation

At AYW Luxury, every piece of jewelry we offer is more than pre-owned — it’s Certified Pre-Owned. Our strict certification process ensures your purchase is authentic, accurately described, and fairly valued.

Authentication: Each item is inspected by trained specialists who verify hallmarks, engravings, craftsmanship, and design details unique to luxury brands like David Yurman, John Hardy, and Lagos. We confirm gemstone identity and metal content with professional testing, then cross-check against brand archives and verified references. Only items that meet our strict standards receive our Authenticity Guarantee.

Valuation: After authentication, every piece undergoes a professional valuation. We provide an Authenticity & Valuation Report that includes gemstone analysis, condition grading (Excellent, Mint, Very Good, etc.), verified metal karat and weight, and a current market value based on comparable resale data.

Certification: Once complete, the item is officially labeled Certified Pre-Owned and delivered with its detailed report. This certification gives you confidence that your jewelry is genuine, accurately represented, and priced with transparency.

At AYW Luxury, we protect you from uncertainty in today’s pre-owned market. Our certification, authenticity, and valuation processes are designed to deliver not just jewelry — but complete peace of mind.
