How We Authenticate Pre-Loved Luxury Jewelry

Buying pre-loved luxury jewelry should feel exciting, not uncertain. One of the questions I'm asked most often is, "How do you know it's authentic?" It's an important question, and one that deserves more than a simple promise. At Louise Row, authentication is at the heart of every piece we offer because trust is just as valuable as the jewelry itself.

Unlike handbags or sneakers, there isn't an app or single database that can authenticate luxury jewelry. Every piece must be assessed individually. Hallmarks, construction, weight, materials, craftsmanship, gemstones, design details, age, and wear all tell part of the story. Authenticating jewelry requires experience, an understanding of how luxury maisons have manufactured pieces over time, and an eye trained to notice when something isn't quite right.

After more than 20 years working with some of the world's leading luxury jewelry houses, I've developed that eye. Every piece is carefully inspected and researched before it's offered for sale. When needed, I work alongside my trusted network of jewelers, gemologists, and luxury retail specialists to verify details and confirm authenticity. If original receipts, certificates, or service records are available, they become part of that process as well. Authentication isn't based on one opinion - it's built on experience, research, and collaboration.

My goal is simple: to give you complete confidence in every purchase. Whether you're investing in a vintage Chanel brooch, a Tiffany & Co. necklace, or a one-of-a-kind fine jewelry piece, you should know that it has been carefully vetted before it reaches the Louise Row collection. When you shop with us, you're not just buying pre-loved luxury - you're buying with confidence.
