FAQs

What types of diamond rings does Diamond Brothers buy?

Diamond Brothers purchases engagement rings, eternity rings, cocktail rings, cluster rings, three-stone rings, halo rings and signet rings featuring diamonds. Rings in platinum, 18k gold, 14k gold, 9k gold and white gold are accepted, including modern, vintage, antique and bespoke designs from across the European market.

How much is my engagement ring worth?

Your engagement ring's value is determined by the diamond's 4Cs (carat, colour, clarity, cut), the metal type and weight, the setting style, and any branded provenance such as Tiffany or Cartier. Diamond Brothers' certified gemologists in Antwerp inspect the ring in person, with GIA, IGI or HRD documentation factored into the final offer where available.

Can I sell a branded diamond ring such as Tiffany or Cartier?

Yes. Diamond Brothers buys branded diamond rings from established jewellery houses including Tiffany, Cartier, Bulgari, Van Cleef Cleef & Arpels, Boucheron, Chopard and Graff. Original packaging, certificates and receipts support the valuation, with branded pieces typically commanding stronger resale figures than equivalent unbranded designs.

Can I sell a diamond ring without a certificate?

Yes. Uncertified diamond rings are accepted by Diamond Brothers and evaluated by certified gemologists in Antwerp. The diamond is graded in-house using standard GIA criteria for colour and clarity, alongside carat weight measurement and cut assessment. The metal is tested separately to confirm purity and weight before the final offer is issued.

What is the resale value of a vintage or antique diamond ring?

Vintage and antique diamond ring values depend on the period (Victorian, Edwardian, Art Deco, Retro), craftsmanship, original cut style (old European, old mine, rose cut), provenance and condition. Pieces from recognised periods with intact original settings and documented history achieve the strongest valuations.

Does Diamond Brothers buy natural diamond rings or also lab-grown diamond rings?

Diamond Brothers specialises in natural diamond rings. Rings set with natural diamonds - whether certified by GIA, IGI or HRD or uncertified - are evaluated based on current market pricing for natural stones. Diamond Brothers does not purchase lab-grown diamond rings.

What is the best way to get the highest price when selling an engagement ring?

To maximise the offer, include the original GIA, IGI or HRD certificate if available, the original box and receipts, and clear photographs from multiple angles before submission. Branded rings from Tiffany, Cartier or similar houses should include any hallmarks or designer documentation. Diamond Brothers' certified gemologists in Antwerp assess each ring individually based on current market demand.
