The Obagem London Standard
A Discreet Alternative to Public Auctions & Pawnbrokers
Selling fine jewelry through public auction houses often incurs 25% to 40% in combined buyer and seller commissions, alongside unpredictable reserve outcomes and months of waiting for auction dates.
At Obagem London, our private advisory offers immediate liquidity. We purchase your diamonds, signed jewelry, bullion, and luxury watches outright, based directly on live global wholesale indices with zero commission deductions.
