Auktionshaus Ineichen

Ineichen Auctioneers runs its sales from Stadthausquai 11, on the Zürich lake shore, and its own site (the German meta line repeated across most pages) describes it as the leading Swiss auction house for watches and jewellery, trading since 1973. That's the company's own framing rather than an independent ranking, but the record behind it is documented on the site itself. Founder Peter A. Ineichen built the house on his interest in the history of chronometry, and by 1975 the young auction house had already sold a Breguet pocket watch, No. 213, for 500,000 CHF. In 1978 it sold two more Breguet pieces, a gold pocket watch with a tourbillon escapement for 500,000 CHF and an astronomical gold pocket watch for 240,000 CHF, both described on the company's own press page as world records at the time. More recently, in 2021, it sold a Konstantin Chaykin "Joker" NFT token for Fr. 52,080, which the same page calls the most expensive NFT from that watchmaker. None of that history matters to someone hunting for a ring rather than a pocket watch, but it explains why Ineichen has the standing to run jewellery lots alongside its watch sales rather than as an afterthought.

What you actually find, once you get past a homepage built almost entirely around watches, is a run of jewellery lots inside both the live room sales and the online timed sales, so the house genuinely does run both formats rather than picking one. A recent timed sale called "Gemstone Symphony" carried a 5.94 ct radiant-cut diamond ring, HRD certified, with 1.75 ct of side diamonds set in 750 white gold and a ring size of 16.75, estimated at CHF 70,000 to CHF 118,000, with a CHF 54,000 opening bid and a CHF 118,000 buy-it-now option. The same sale carried a 2.55 ct diamond ring with a GIA certificate, size 17, listed with a CHF 285,000 buy-it-now price. Auction stock turns over fast (lots close, sell, and get replaced within weeks), so treat those two rings as a snapshot of what shows up rather than a live stock list. What they do prove is that Ineichen deals in graded, certified stones with paperwork attached, not loose "diamond-look" jewellery you have to take on trust.

What stands out for a buyer who isn't Swiss and doesn't plan to stay in Zürich forever is the fee structure. Ineichen dropped its buyer's premium entirely in May 2022, so what you owe on a winning bid is the hammer price plus tax and nothing else. Collect from the Stadthausquai office and Swiss VAT is added at the standard rate of 8.1% of the hammer price. Export the piece instead, carrying it home yourself or shipping it abroad, and that 8.1% is refundable once you hold a stamped customs export declaration, with a minimum refund threshold of CHF 30. That's a genuinely transparent way to price an auction purchase, and it matters more to an expat than to a Zürich local: you can work out your total cost in CHF before you bid, and you know it drops the moment you're not keeping the ring in Switzerland.

How buying actually works

Ineichen supports four ways to bid: live online during the sale, in person in the auction room (in-room bids are prioritised over online ones when both land on a lot at the same moment), by telephone arranged in advance through info@ineichen.com or +41 44 298 11 44, or by leaving a maximum bid ahead of time that the system executes incrementally up to your ceiling without you having to watch the clock. None of the four requires you to be in Zürich, or even awake at the same hour as the room. Increments move with price: they start at CHF 50 for bids under CHF 1,000 and rise to CHF 25,000 once a lot passes CHF 500,000. Once a bid is placed it cannot be withdrawn or changed, so it's worth checking your numbers before you confirm.

Payment is due at the auction itself or within 5 days of it. Ineichen accepts cash in CHF at its office, or bank wire in CHF, EUR or USD through Wise, but it does not currently take card payments, which is worth knowing if you assumed you'd settle with a credit card from abroad. Miss the deadline and interest runs at 10% a year on the net hammer price; keep missing it and the house can cancel the sale outright and charge 10% of the hammer price as expenses. On delivery, you can collect in person within 30 days of the sale, though a storage fee applies once you pass 10 days, or you can arrange shipping yourself through Ineichen's recommended partner, Tibbett+Britten Unique AG, at your own cost. Pieces can also sit in the Zürich Freeport, which is a genuinely useful option if you might be leaving Switzerland within a year or two and don't want to settle the VAT question on something you're not planning to keep in the country long term.

On authenticity, Ineichen offers a lifetime guarantee against counterfeits. Outside that, returns are narrow: they're limited to forgery claims made within 30 days of the sale, backed by expert proof, with the item back in Ineichen's hands within 14 days. If you buy a ring here and it turns out not to fit, or you simply change your mind, none of that is covered, and there's nothing published anywhere on the site about a resizing service. Budget for a jeweller separately, and if you can, try the ring on or at least confirm the size before you commit money you can't get back on a whim.

How it compares

Ineichen sits in the same Zürich jewellery-auction circuit as Koller, Schuler, Rapp and the Swiss desks of Sotheby's and Christie's, all of which run their own dedicated jewellery sales with public viewing days. What sets it apart on paper is the fee it dropped rather than any it kept: a trade-press report on the 2022 change (an independent watch publication, not Ineichen's own copy) called it the first Swiss auction house to remove a buyer's premium, describing the commission it replaced as running 20-30% on the hammer price elsewhere in the trade. Whether every rival still charges that much today isn't something Ineichen's own site can confirm for us, but it does show the direction the house moved in, and a no-premium structure is unusual enough in this market to be worth knowing before you assume auction pricing works the same everywhere you look.

Ineichen also runs a private-sale and consignment arm, though its own marketing for that side is pitched mostly at watches rather than jewellery. It advertises selling a piece for 10-30% above market value, a listing process it says takes within two weeks of consignment, a stated success rate of 75-90%, and a commission it describes as at least 10% lower than other auction houses. Those figures come straight from Ineichen's own sell-side page, aimed at people bringing something in rather than bidding on something already listed, so read them as marketing rather than an audited rate card. They're still worth flagging if you buy a ring here and later want to sell it back through the same house, for instance if you leave Switzerland after a few years and would rather consign the piece than carry it home.

Who it suits

This is a solid stop for an international buyer in Zürich who wants a certified stone (both ring examples above carried HRD or GIA paperwork) at an auction price rather than a boutique markup, and who is comfortable bidding without a Swiss friend on hand to translate: the site runs in English, the phone line takes English calls, and none of the bidding routes require you to show up in person. It also suits someone who wants to do real diligence before they spend, since Ineichen publishes condition reports and certification per lot instead of leaving buyers to take the seller's word for it.

It suits that same reader less well if what they actually want is retail-style after-sales care. There's no ring resizing on offer, no card payments if that's how you manage money abroad, and a return policy that only covers proven forgery, not buyer's remorse or a size that doesn't work. Someone who wants to walk in, try three rings on, and walk out with one properly sized is better served by a boutique than by an auction house, however well run.

The verdict

Ineichen is a credible first stop for buying a ring at hammer rather than at retail in Zürich: trading under one name since 1973, a real office you can visit on the lake shore, certified stones with proper grading paperwork attached to the lots we checked, and a fee structure, no buyer's premium plus an 8.1% VAT that's refundable if you're exporting the piece, that's about as easy to calculate in CHF as auction pricing gets anywhere. Its Trustpilot page shows a 2.9-star average from 9 reviews, a small sample worth knowing about, though it's easy enough to check the auction house's own track record and current lots independently rather than lean on that score alone. The site leans hard toward watches in its navigation and its own marketing, so don't expect a dedicated engagement-ring department: expect to hunt for jewellery lots inside a wider catalogue. For an expat buyer who's comfortable doing that hunting and bidding from a distance, the transparency on total cost is the real reason to put Ineichen on the list.
