La Serlas

La Serlas is the newest boutique on this list by address, though not by age. The brand traces itself back to a shop Heinrich Schmid opened in St. Moritz in 1979, on the square facing the Palace Hotel, and it only reached its current Zurich form recently: the boutique and workshop at Fortunagasse 26 opened in 2025. For an expat weighing where to buy a ring, that combination matters more than it sounds. A young Zurich address is backed by a family jewelry business that has been trading for decades, and is now run day to day by the founder's son.

That son, Christopher Schmid, took over the Zurich side of the business. By the company's own account he trained under his father from childhood, then spent time in gem markets across Asia, in European ateliers, and on 47th Street in New York, the traditional center of the American diamond trade, before coming back to run things himself. His name is the one on the contact page too: inquiries go to christopher@laserlas.com, and the Zurich commercial register lists him as the company's board member with individual signing authority.

The company behind the boutique is La Serlas Zurich AG, a Swiss stock corporation founded on 30 August 2021 and capitalized at CHF 200,000, split into 200 registered shares. That is worth stating plainly for anyone trying to work out whether a shiny new-looking storefront is a serious, permanent business or something dressed up for a season of Bahnhofstrasse tourism: it is registered as an ordinary Aktiengesellschaft, with a stated purpose covering the trade of jewelry, watches, art objects and antiques, plus consulting on jewelry design. The brand's own history runs earlier than the current AG. After the 1979 opening in St. Moritz, the business expanded to Zurich's Bahnhofstrasse in 1992, and it only moved into the current Fortunagasse address, a short stretch of old town between Bahnhofstrasse and Rennweg near the Lindenhof, when the new boutique and atelier opened in 2025.

Inside, the range runs from ready-to-wear pieces to one-of-a-kind bridal jewelry. The site groups stock by category (rings, earrings, necklaces, bracelets) and by stone (white diamonds, colored diamonds, sapphires, rubies, emeralds, pearls, and other gemstones), plus two signature lines: Serlas Pink for pink diamonds, and Lemon Pepper, a yellow-diamond collection set against white diamond accents. The higher-value bridal pieces carry grading paperwork rather than a public price tag. A Toi et Moi ring built around a 1.39 carat D-color, VVS1-clarity pear-shape diamond, paired with a 0.90 carat Fancy Vivid Yellow VS1 pear-shape stone, both GIA-certified, has no price on its own product page at all, just a "Request Information" link and a phone number. That is a real gap for anyone used to shopping by list price, though it is standard practice for a one-of-a-kind stone at this level, and it is at least consistent: nobody selling a five-figure custom diamond is going to quote francs and centimes on a product page.

What La Serlas does publish prices for is its own-line jewelry outside that top tier. A Lemon Pepper white and yellow pear diamond tennis bracelet is listed at CHF 6,800.00, an 18-karat rose gold La Serlas bracelet set with 0.375 carats of diamonds at CHF 4,000.00, and a La Serlas Waves bracelet in white gold at CHF 4,500.00. None of those is an engagement ring, but they give a newcomer a real anchor for where the house sits on price, and having any figures on the site at all puts it ahead of Bahnhofstrasse jewellers that route every question through an inquiry form.

For an engagement ring specifically, the boutique steers buyers toward its bespoke service rather than the fixed catalogue. The bespoke page invites a client to bring in a family stone to reset, a sketch of something specific, or simply an idea to work from, and describes the result as "tailored to your taste and budget." Design happens with Christopher's in-house team; the physical making goes out to named partner workshops, Atelier Cavalli and Atelier Crincoli, the latter described on the site as one of Zurich's finest. What the site does not publish anywhere is a lead time, a consultation fee, or a minimum budget for a commission. Anyone planning a proposal around a fixed date should ask directly rather than assume a standard turnaround; neither this site nor its Bahnhofstrasse-area peers publish those figures, so it reads as an industry norm rather than a mark against La Serlas specifically, but it is worth naming rather than guessing at a number.

Getting there and getting an answer

The boutique sits at Fortunagasse 26, postcode 8001, an easy add-on stop if you are already comparing rings at the bigger houses nearby on Bahnhofstrasse. Opening hours are published without ambiguity: Monday to Friday from 10am to 6pm, Saturday from 10:30am to 5:30pm, closed Sunday. That is ordinary retail access rather than appointment-only, which suits someone trying to fit a viewing around a work week rather than book weeks ahead. There is a landline for the boutique, a separate mobile number for questions outside those hours, and a contact form with preset subjects covering things like product inquiries, press, and returns. The whole storefront runs in English by default, with no separate-language version to hunt for first, a small but real convenience next to sites that make an English speaker click through menus to find their language.

One thing the site stays quiet on is anything cross-border. It has a page titled "Shipping time," but the content is a single chart image with no text underneath it, so nothing readable there covers delivery windows, couriers, or customs and duty. For an expat buying a ring to send home, or planning to leave Switzerland with a piece bought here, that is a real question rather than a small one, worth raising with Christopher's team directly before ordering rather than assuming standard EU shipping norms apply. The same goes for resizing or repairs once you own a piece: nothing on the site sets out a resizing policy or an after-sales guarantee, so that is also a conversation to have before buying rather than an assumption to carry in afterward.

How it compares, and who it suits

Much of this tenant's Bahnhofstrasse-and-old-town shortlist leans on multi-generation institutions that have traded from the same address for a very long time. La Serlas is not that, and its own marketing does not pretend otherwise: it describes itself as "reborn in Zurich" with a fresh boutique, not as another old-guard fixture on the strip. What it offers instead is a smaller, design-forward alternative for a buyer who wants a distinctive look, the pink and yellow diamond lines are not generic, and who does not mind that the shopfront itself only opened in 2025. The history behind that storefront gives it real weight rather than leaving the design to stand on its own: a 1979 founding, a second generation now running the Zurich operation, and named workshop partners for the physical making of every piece.

That mix suits a particular kind of buyer best: someone who already wants something more distinctive than a standard round-brilliant solitaire, who is comfortable asking directly about price and turnaround on a custom piece rather than reading it off a page, and who values walk-in retail hours and an English-first site over the ceremony of an appointment-only atelier. It suits less well a buyer who wants firm numbers in hand before walking in the door: the certified bridal diamonds this list is really about are the ones priced on request rather than listed outright.

None of that is a reason to skip it. A registered, properly capitalized Zurich company, an on-site goldsmith's workshop, GIA paperwork on its certified stones, and a family that has been in the jewelry trade since 1979 add up to a legitimate, well-run boutique, just a young one at this particular address. For an expat who wants Bahnhofstrasse-adjacent shopping without an old-guard sales pitch, it is worth the short walk off the main street to see the collection in person and ask its own team the questions its website leaves open.
