Send your jewellery here
At Prometeo London, we are passionate buyers of antique, vintage, and second-hand jewellery. We offer competitive prices, a transparent process, and immediate payment for pieces with character, craftsmanship, and story.
We are particularly interested in:
• Antique jewellery from the Georgian, Victorian, Edwardian and Art Deco periods
• Vintage designer pieces, including signed jewellery by Cartier, Tiffany & Co., Boucheron, Bulgari, and others
• Gold and platinum jewellery, even if worn or incomplete
• Diamond rings, brooches, lockets, bracelets, earrings and necklaces
• Loose gemstones, including diamonds, emeralds, sapphires, rubies and pearls
Whether you wish to sell a single piece or a full collection, we treat each item with discretion, respect, and expert knowledge.

What We Look For
To provide you with the best possible offer, we recommend sharing:
• Clear photographs (front, back, hallmarks, any details)
• Any provenance or history (who it belonged to, origin)
• Certificates or receipts, if available
• A note on the condition of the item or stones
Our valuations consider the craftsmanship, period, metal weight, gemstones, condition, and current market value.

Why Sell to Prometeo London?
Selling jewellery can feel overwhelming. That’s why we aim to make the process simple, fair and rewarding.
Here’s why clients choose us:
• Immediate payment once an offer is accepted
• No commission fees or hidden costs
• Expert evaluation with a deep understanding of antique and vintage pieces
• Personalised, private service in our Chelsea boutique
• Trusted by collectors, heirs, and private sellers alike
We are not a pawn shop or high-street chain — we’re specialists in timeless jewellery with stories to tell.

Auction vs Private Sale
You might consider selling at auction — but be aware:
• Auction fees can take up to 30% from the final sale price
• If your item doesn’t sell, you still pay charges
• The process can take months, with no guarantee of sale
• Jewellery that goes unsold at auction may lose appeal on the market
By selling directly to Prometeo London, you avoid delays and commissions, and receive a clear, professional offer based on real expertise.
