Cyrill Streuli Schmuck & Design

Cyrill Streuli Schmuck & Design is a one-person goldsmith atelier working out of a home studio on Spinnereistrasse in Langnau am Albis, inland from the lake on the Sihltal side of the Zurich Oberland rather than on the water itself. There is no shopfront to walk past and no showroom window to browse. The site itself puts it plainly: custom pieces, repairs and alterations, with engagement rings, necklaces and wedding rings made in gold using traditional goldsmith craft. For anyone who has already toured the display cases on Bahnhofstrasse and wants something closer to a design conversation with the person actually making the ring, this is the kind of listing this category exists for.

Cyrill Streuli has been running the atelier under his own name since 2022, but he is not new to the trade. His own site states over 15 years of professional experience, including 5 years as atelier manager (Atelierchef) at an established jeweller in the city of Zurich, a claim that lines up with a short piece the Weltwoche ran on him, which describes fifteen years working at various jewellers and goldsmiths around Zurich before he struck out with his own designs. He also currently holds a listed executive role, COO and Geschäftsführer, at Faktor S Goldschmiede & Chronometrie, part of Sahak Jewellery AG, which runs a head office in Zurich and a branch in Winterthur. That is a separate business from the Langnau atelier, and this listing is about the Langnau practice, but it is a useful data point for a buyer trying to size up an unfamiliar one-person operation: the person behind it also sits in a senior role at an established Zurich jewellery house.

What you get

The core offer matches what most readers on this list are searching for: engagement rings and wedding rings (Verlobungsringe and Trauringe, in the site's own German), plus necklaces, made to order in gold rather than picked from a case. His portfolio page shows work across red, rose, white and yellow gold, all cast at the standard 750 fineness (18 karat), and a handful of pieces that step outside gold entirely into steel with a PVD coating or tantalum, mostly for men's bands. Stone-set work in the same portfolio runs from diamond and sapphire through tourmaline, indigolite, aquamarine, amethyst, garnet, mandarin garnet, a Tahitian pearl and emerald, so the range of past commissions is wider than a typical engagement-only specialist. Beyond new commissions, the site lists repairs for rings that no longer fit, fixes for torn bracelet links, and cleaning and polishing ahead of an occasion, which matters if you already own a piece and just need it brought back to shape rather than replaced.

A CAD-first workshop that still calls itself a craft business

Where this atelier differs from a purely traditional one is the design process. The services page says engagement and wedding rings are made "with the help of the latest CAD technology," and the know-how page goes further, framing CAD not as a shortcut but as a tool that needs a goldsmith's judgment behind it: "many master the ABCs of CAD, but only a few can apply it like a goldsmith," and elsewhere, "I think and work with CAD like a traditional craftsman." In practice this means a ring can be modelled, rendered and checked for setting and casting before any metal is cut, which tends to shorten the back-and-forth over how a design will actually look and fit compared with sketch-only work. He also offers that CAD know-how to other jewellery studios directly, as consulting: modernisation support, staff training, workshops, and production of pieces from a client's own designs, with the site claiming this can make other studios' production up to 50 percent more economical. Worth being precise about what that figure covers: it is a claim about his consulting service for other goldsmiths' workflows, not a discount or fixed cost for a couple commissioning their own engagement ring.

The clearest proof of that CAD-and-craft combination is a separate project he runs under its own brand, ENIGMA, from the same Langnau am Albis address. It is not a general engagement ring at all, but a specific mechanical design: a band set with three inset rings that the wearer turns to encode a personally chosen word, which the site describes turning "in a few twists" into an attractive, cryptic pattern, with "the fine mechanism clicking quietly" as it moves. The name comes from the Greek ainigma, meaning riddle. It will not be what most readers want for a straightforward solitaire, but it is a strong signal of design ambition and technical control from a workshop this size, and it is worth a look even just as evidence of what the studio can build.

What an international buyer in Zurich should actually expect

This is where the site is thinner than a newcomer to Zurich would want. There is no published price list, no stated lead time for a custom engagement ring or wedding band, and no mention of what happens if you need to resize a ring after a year or two, which matters if you are only in Switzerland for a limited posting. The navigation mixes an English label, "My Work," with otherwise German-language pages, but there is no dedicated English version of the site and no statement about which languages consultations happen in. Nor is there anything published about shipping, customs or duty for a buyer who might commission a piece and later leave the country. None of this means the atelier cannot handle these things, plenty of small Swiss workshops sort out language, timeline and logistics over a first phone call or email rather than publishing them, but it does mean a prospective client should ask directly and get it in writing before committing rather than assuming.

On outside verification, there is not much yet: a ProvenExpert profile aggregates a single review, sourced from Google, at 5 out of 5 stars. That is a thin sample size for a business asking for trust with a significant purchase, though it is at least a real, positive data point rather than nothing, and it fits with a workshop that has only carried its own name since 2022 after years spent inside other people's businesses.

Who it suits, and the verdict

This listing suits a buyer who wants a genuinely custom, CAD-designed engagement or wedding ring in gold, is comfortable communicating in German (or willing to confirm English is workable before booking), and is not in a rush against a tight relocation or wedding date, given that no lead time is published to plan against. It is less suited to someone who wants price certainty up front, a shop they can walk into on a Saturday, or an English-first experience end to end.

The genuine caveat here is transparency: prices, timelines, appointment process and language of service all need to be asked for directly rather than read off the page, and outside reviews are still scarce. Set against that is a real, currently trading business run by a goldsmith with over 15 years in the trade, a current senior role at an established Zurich jewellery house, a CAD-driven design process he is happy to explain in detail, and a distinctive piece of original design work in ENIGMA that few workshops this size would attempt. For an international buyer willing to make first contact and confirm the details before committing, it is a legitimate, worthwhile option outside the main shopping streets.
