Authenticity Promise

At DSF Antique Jewelry, authenticity is at the heart of everything we offer. Each piece in our collection is carefully reviewed before being presented to our clients, with attention to materials, craftsmanship, condition, period, maker’s marks, signatures, hallmarks, and overall design consistency.

Our inventory includes antique jewelry, vintage jewelry, signed designer pieces, luxury watches, rare objects, and carefully selected fine jewelry. Because these categories often require specialized knowledge, we evaluate each item through a combination of experience, research, and close physical examination.

Our Approach to Authentication

Every piece offered by DSF Antique Jewelry is examined with care. Depending on the item, this may include reviewing:

• Designer signatures and maker’s marks
• Metal purity marks and hallmarks
• Gemstone quality and setting style
• Period-appropriate craftsmanship
• Construction details, clasps, hinges, and backs
• Serial numbers, where applicable
• Provenance, documentation, or packaging, when available
• Condition and signs of repair, alteration, or restoration

A signature alone is never treated as the full story. We consider the entire object, including how the piece was made, how it has aged, and whether its details are consistent with the designer, period, and materials.

Signed Designer Jewelry

Signed jewelry by houses such as Cartier, Van Cleef & Arpels, Tiffany & Co., Chanel, Dior, Bulgari, Boucheron, and other important names requires particular attention. These pieces are evaluated not only for their signatures, but also for craftsmanship, design language, construction, and market context.

Because signed designer jewelry can vary by period, country, collection, and production method, we review each piece individually rather than relying on general assumptions.

Antique and Vintage Jewelry

Antique and vintage jewelry often carries signs of age, previous ownership, and hand craftsmanship. These characteristics can be part of a piece’s beauty and historical value. At the same time, we carefully consider condition, originality, restorations, and any alterations that may affect collectibility or value.

When appropriate, we describe pieces as antique, vintage, estate, signed, or designer according to their nature and available information.

Condition and Transparency

DSF Antique Jewelry strives to present each item accurately and transparently. Our pieces are selected for quality, beauty, rarity, and collector appeal. Unless otherwise noted, items are offered in excellent estate condition.

If a piece has a meaningful condition detail, repair, alteration, or special note that affects its presentation or value, we aim to disclose that information clearly.

Documentation and Provenance

Some pieces may come with original boxes, receipts, certificates, service papers, or other documentation. These materials can support a piece’s history, but they are not a substitute for examining the jewelry itself.

Whenever documentation is available and relevant, it may be included in the product description or provided upon request.
