Frequently Asked Questions
Everything you need to know about selling fine jewelry, certified diamonds, bullion, and luxury timepieces with Obagem London.
How is the valuation of my diamond or jewelry determined?
Our valuations are established directly on live international wholesale benchmarks: the weekly Rapaport Diamond Report for certified diamonds, real-time LBMA London spot fixing for gold bullion and coins, and verified global auction databases for signed jewelry and luxury timepieces.
Do you purchase uncertified diamonds?
Yes. While certificates from GIA, AnchorCert, or HRD streamline the process, our senior gemologists possess complete laboratory instrumentation to grade uncertified stones on-site in our Mayfair or Hatton Garden salons.
What documents are required to complete a sale?
In compliance with UK anti-money laundering and trade regulations, sellers must present a valid government-issued photo ID (passport or UK driving licence) and proof of address. Any accompanying gem certificates, original receipts, or manufacturer boxes should also be provided.
How quickly do I receive payment?
Payment is executed immediately upon agreement via UK Faster Payments or CHAPS electronic bank wire transfer. Funds reflect in your account within minutes. We can settle in GBP (£), EUR (€), or USD ($).
Can an appointment be arranged at my home or bank?
Yes. For clients managing significant estates, collections, or security considerations, our accredited specialists travel to private residences, family offices, and bank vaults across Mayfair, Knightsbridge, Kensington, Hampstead, and Greater London.
Are there any fees if I decline your offer?
None whatsoever. All consultations and appraisals are 100% complimentary with zero pressure and zero obligation to sell.
