Preziosi Auctions UG is a Germany-based online auction house and marketplace specialising in jewellery, watches, gemstones, luxury objects and collectibles.
We operate an online-only platform through which Buyers can discover, bid on and purchase selected items. We also provide approved professional and private Sellers with access to a digital marketplace for offering eligible goods for sale.
Our Platform is designed to connect Buyers and Sellers in a secure, transparent and convenient online environment.
Depending on the relevant transaction, Preziosi Auctions may act as:
1. the seller of an item;
2. the operator of an online auction;
3. the operator of a marketplace;
4. an intermediary between Buyers and independent Third-Party Sellers;
5. a provider of authentication, payment, delivery, collection or customer-support services.
The role of Preziosi Auctions and the identity of the relevant Seller will be indicated on the applicable item or Lot page where required.

2. OUR BUSINESS MODEL
Preziosi Auctions combines the functions of an online auction house and a curated marketplace.
2.1 Online-Only Auctions
Our auctions are conducted exclusively online. Buyers may register, review Lots, place bids and complete purchases through the Platform without attending a physical auction.
Auction Lots may be offered:
* directly by Preziosi Auctions;
* on consignment;
* by approved professional Third-Party Sellers;
* by approved private Sellers, where permitted.
Each auction will include relevant information concerning the auction period, starting bid, reserve price, bidding increments, applicable fees and delivery arrangements.
2.2 Marketplace
The Marketplace allows approved Sellers to offer eligible items through:
* fixed-price listings;
* online auctions;
* consignment arrangements;
* other sale formats made available by Preziosi Auctions.
Where an item is offered by an independent Third-Party Seller, the contract of sale is generally concluded directly between the Buyer and that Seller.
Preziosi Auctions operates the Platform and may provide additional services as described on the relevant item page, in the applicable Terms & Conditions or in the relevant Seller agreement.
