Juwelier Frech

Juwelier Frech sits at Bahnhofstrasse 56, right by the tram stop at Rennweg, and it is a different kind of stop on this street from the big multi-brand houses around it. Where its neighbours sell watches and jewellery from a roster of outside brands, Frech designs and makes its own gemstone jewellery on site, and has done since Jürg Frech took the shop over under his own name in 1995. The business itself goes back further than that year alone suggests: Frech had spent years working under the previous owner of the same address, a shop trading as Langemann, before striking out with the help of friends who helped him renovate the store on a tight deadline and a tighter budget. It's a smaller story than Beyer or Gübelin tell about themselves further down the street, and Frech doesn't try to compete on scale. It competes on what it actually makes.

What you get

Frech's own training explains why the shop leans on coloured stones rather than diamonds alone. He developed his interest in gemstones and pearls while working in Canada, then went on to graduate in 1982 as a gemologist from the Gemological Institute of America, specialising in coloured gemstones, pearls and diamonds. That background shows up directly in the collection: rubellite, paraiba tourmaline, mandarin garnet, tanzanite, jade, moonstone, and both crystal and black opal from Australia sit alongside diamonds and pearls, each piece built around a named stone rather than a generic setting. A "Hot Pink" rubellite of 13.32 carats, a paraiba tourmaline the shop calls "Hollywood-Blue" at 143 carats, and an aquamarine at 39.98 carats are among the display pieces shown on its jewellery page, alongside a 25.74 carat mandarin garnet nicknamed "Fanta." These are pieces the shop has made and photographed, not a fixed stock list, but they show the scale and type of stone Frech works with.

The shop is now a two-generation operation. Alex Frech, Jürg's son, joined the business in 2023 after a six-year goldsmithing apprenticeship at another well-known Zurich jewellery house, a diploma in salesmanship and management, and five years working for a precious-metals supplier in Zug. He's described on the company's own site as still learning the business from his father while bringing his own ideas to it, which reads as an honest description of a family firm mid-handover rather than a finished one.

On materials, Frech states its policy plainly: it uses only recycled gold and platinum, and it sources gemstones from what it calls known and trusted dealers rather than naming specific suppliers. Rarer stones are certified through independent gemological laboratories, and the spread named on the site is genuinely wide: GIA, SSEF (the Swiss Gemmological Institute), GRS (Gemresearch Swisslab), Gübelin Gem Lab and GGTL Liechtenstein. For a buyer paying for an unusual coloured stone, that list of labs matters more than a brand name over the door, since it means the stone's identity doesn't rest on the seller's word alone.

What stands out

Frech also holds the retail rights to ProHunter, a line of customised Rolex watches, separate from the gemstone jewellery it designs itself. Its own news page describes the ProHunter World Time as the first Rolex fitted with 24-hour world-time tracking, with a fully customisable dial and bezel; that side of the business starts from someone else's watch rather than Frech's own design, so it's worth knowing about but isn't the reason to visit for a ring. The gemstone side is the more relevant one here. Recent pieces documented on the site include an 18kt rose gold ring built around a large trillion-cut yellow gemstone with diamonds set around it, and the "Dolce Vita" ring, an 18 karat yellow gold design originally made for a client of the shop's previous owner before Frech took the business over in 1995. That design has since been reissued in a limited run of 10 pieces, each individually numbered on the inside of the band. Since mid-December, a rotating selection of the jewellery has also gone on display in a ground-floor vitrine at the Mandarin Oriental Savoy on Paradeplatz, a short walk from the Bahnhofstrasse shop, with the pieces on show there changing monthly.

One thing worth flagging directly: Frech's site has no dedicated engagement ring or bridal section, and no catalogue of plain solitaires to browse before a visit. What it shows instead is a rotating set of one-off, gemstone-led designs, which suits a buyer who wants something built around an unusual stone rather than a standard round-brilliant solitaire pulled from a case. If you already know you want a straightforward diamond solitaire and want to compare several side by side in one visit, a bigger multi-brand house on the same street will show you more of that kind of ring. Frech's strength is the opposite kind of shopping trip: walking in with an idea, a stone you like, or a design you've seen somewhere, and asking what the workshop can build around it.

For newcomers to Zurich

For someone new to the city, the practical details matter as much as the design story. The shop's own site is written mainly in English, with only the short introductory line kept in German on every page, a reasonable sign that staff are used to serving customers who don't speak German day to day, even though the site never states this outright. Opening hours are Monday to Friday, 9am to 6:30pm, and Saturday 10am to noon and then 2pm to 4pm, with a midday break on Saturdays worth remembering if you're planning a weekend visit. There's no online shop, no published shipping, export or duty information for a buyer ordering from abroad or leaving Switzerland later, and no visible booking form anywhere on the site, so the practical way in is to phone the shop directly or walk in during those hours rather than reserve a slot online.

Pricing follows the same pattern of simply not being published. Nothing on the gemstone or jewellery pages carries a price, and the one place the site does mention pricing at all, the ProHunter watch page, states plainly that the price is on request. The gemstones page notes that a stone's value depends on its purity, size, colour and market availability, which is useful context for judging a stone but nowhere close to a number to budget against. Anyone weighing a commission here should plan for that first conversation, by phone or in person, to be where the real pricing and any lead time actually get discussed, since none of it sits online beforehand.

How it compares

Set against its Bahnhofstrasse neighbours, Frech's case is narrower but genuine. It's a small, family-run design house rather than a multi-brand retailer, and the range of coloured stones and the spread of certifying labs behind them stand up well against much bigger names on the same street. It doesn't have Beyer's centuries of history or Gübelin's global reach, and it isn't trying to. What it offers instead is one workshop's own designs, made by two generations of the same family, with the paperwork to back the stones up.

Who it suits

This is the right stop for a buyer who wants a genuinely one-of-a-kind engagement ring built around a coloured stone, who is comfortable having the pricing and timeline conversation in person rather than online, and who doesn't need to compare several ready-made solitaires before deciding. It's a weaker fit for someone who wants to see a full range of plain diamond rings before committing, or who needs a delivery date or a price confirmed in writing before making the trip, since none of that is published anywhere on the site.

The verdict

Juwelier Frech earns its place on this list for being exactly what it says it is: a small, independent Bahnhofstrasse jeweller that designs its own gemstone jewellery rather than reselling someone else's, built by a founder with a genuine gemology credential and now carried forward by a second generation. The lack of a published price list or a dedicated engagement ring page is a real gap for anyone trying to plan the whole trip online, but it's the kind of gap a short conversation at the counter closes quickly, and the stones and workmanship on show are worth having that conversation.
