EDIGEM

EDIGEM sits in the vintage and antique bracket of this list for a straightforward reason: unlike the auction houses that only sell what happens to come up under the hammer, EDIGEM buys, appraises and sells estate jewellery and antique rings as its actual business, year round, from two Swiss cities. It's a subsidiary of the Gübelin Group, the well known Lucerne gemological family firm, and its own marketing puts the trading history at over 35 years, though the Zurich boutique the international crowd tends to find first is not the original address. That's in Lucerne, at Maihofstrasse 102, where the head office sits alongside a separate retail boutique on Hofstrasse in the old town. Zurich is a genuine, staffed second location at Limmatquai 62, not a satellite showroom that only opens by appointment, but it's worth knowing going in that Lucerne is where the company itself is rooted.

What you get here is closer to a private jeweller's counter than an auction lot: a piece for sale, a price you can ask about directly, and staff on hand who can also value or buy jewellery you already own. EDIGEM's own language splits the offer into three: selling jewellery to you, buying jewellery from you (with what it calls a free, no obligation purchase offer reflecting current market value), and appraisals for insurance, inheritance or a second opinion before a sale. For a newcomer sorting through a family piece or hunting for an antique ring that doesn't look like everyone else's, that structure is convenient: you can walk in with a question about a ring you're selling and walk out having also looked at rings for sale, in the same visit.

Documentation and credentials

This category ranks on paperwork more than on photography, and EDIGEM's is stronger than most walk in dealers. Staff hold recognised gemological credentials, the site cites the F.G.A. diploma from the Gemmological Association, the Graduate Gemologist (G.G.) certification, and diplomas from the Federation for European Education in Gemmology, and the company is a member of the Swiss Gemmological Society. Valuations are done, in the company's own words, to international appraisal criteria, whether for a single ring or an entire inherited collection. That matters more here than the setting or the photograph, because a vintage ring's value rides on a correct read of the stone and the metal, not on how the listing is styled.

The Gübelin link adds weight rather than just a name to drop. Gübelin's own site points buyers toward EDIGEM specifically for purchase and appraisal work, describing its experts there as specialised in buying, selling and assessing valuable jewels. EDIGEM operates as an independent company rather than a Gübelin storefront, so don't expect a Gübelin certificate to come as standard on every EDIGEM piece, but the family connection is easy to verify and hard to fake.

Two cities, more than one address

The Lucerne headquarters at Maihofstrasse 102 is the administrative base and where phone enquiries land first on weekdays. Lucerne also has its own retail boutique on Hofstrasse in the old town, reopened in July 2023 with what the company describes as an expanded concept, separate from the head office. Zurich's boutique, at Limmatquai 62, is registered in its own right as a branch office rather than run purely as an extension of Lucerne on paper, which fits what you find on the ground: a proper storefront with its own phone line and its own hours, open Tuesday to Friday from 10:30 to 18:00 and Saturday 10:30 to 16:00, closed Sunday and Monday. If you only have a Tuesday afternoon free between meetings, that schedule is worth checking before you go, since the Monday closure catches a few visitors out.

For anyone new to Zurich, the practical read is this: Zurich is not a branch in the diminished sense of the word. It's a working boutique in the old town with its own stock and its own staff, and EDIGEM's page for it specifically mentions serving an international clientele, alongside references to houses like Van Cleef & Arpels, Harry Winston and Cartier among the kind of jewellery that passes through the doors. The site runs in German and English, so language on the page isn't a barrier, though it doesn't spell out whether every staff member on the floor will run a consultation itself in English. Book ahead if that matters to you, and just ask when you call.

What the site doesn't say, and what's worth a call

EDIGEM doesn't publish prices, so nothing here can tell you what an antique ring runs before you visit. It also doesn't publish anything about resizing, delivery times for a commissioned piece, or shipping and duty if you're buying from outside Switzerland or plan to leave with a piece when your posting here ends. None of that is unusual for a boutique jeweller working face to face rather than online, and the company does describe a worldwide network of business partners it draws on to track down a particular stone or period piece, which suggests it's used to sourcing for clients who aren't shopping off a shelf. But if lead time or export paperwork is what decides things for you, that's a phone call or an email before a visit, not something you'll find by scrolling the site.

How it compares, and who it suits

Set against Koller or Schuler, the two auction houses that anchor this category, EDIGEM is the opposite shape of business: no calendar to wait for, no viewing day, no bidding, just a piece you can see and buy, or sell, on a normal shop day. That suits someone who wants a specific ring now rather than whatever happens to be in the next sale, and it suits anyone selling a piece who would rather get a same day offer than consign it and wait on auction results. It suits less well anyone hunting for a bargain against a hammer price, since a dealer's margin sits inside a fixed price rather than getting settled in a room.

The honest caveat is that you're trading price transparency for convenience. You won't know what you're paying until you ask, and a couple of the practical questions an international buyer cares about most, shipping and lead times chief among them, aren't answered on the site. Weighed against a genuinely credentialed, Gübelin linked dealer with a real, staffed Zurich address and a documentation first approach to valuation, that's a minor gap rather than a reason to look elsewhere. For a vintage or antique ring bought with proper paperwork behind it, EDIGEM earns its place on this list.
