Frequently Asked Questions

What is a Buyer’s Premium? How much is it?

Buyer’s premium is a charge in addition to the hammer price of an auction item, or lot. The winning bidder is required to pay both the hammer price and the percentage of that price called for by the buyer’s premium.

Fees for buying are 13% (incl GST) if you sign up through our Jewellery Auctions platform or 16% if you sign up through the Invaluable platform.

We recommend registering through our platform to lower your costs.
