A broker that works for the buyer
Duxby Diamonds is run by Kate and Eric. We have no showroom to fill and no stock to push, so every deal is negotiated for the buyer, not the seller.
As a team, we bargain, barter and trade with suppliers on your behalf. We push for a competitive price, and we check that the stone you receive is the stone you paid for. See how we negotiate.
