Lang Antique & Estate Jewelry

Lang Antique & Estate Jewelry sells its own stock of Victorian, Edwardian, Art Deco and mid-century pieces from a store in San Francisco's Union Square shopping district, and has done since 1969. It buys and sells its own jewelry rather than reselling other dealers' lots, so what you see on the site is what it actually holds in San Francisco, not a listing pulled together from elsewhere. For someone in Zurich who wants an era Koller's and Schuler's sale calendars might not cover in a given season, or who simply cannot make a viewing day, that is the whole appeal: a specialist collection reachable by video call and FedEx rather than a plane ticket.

The site organizes its engagement rings by shape, by setting type, and by period (Victorian, Edwardian, Art Deco, Mid-Century, and a broader Gemstone category), alongside its own Lang Collection line, new rings built around vintage diamonds in period-inspired settings for anyone who wants the look without the wear history. Every piece carries a price online in US dollars, so there is no back-and-forth to find out what something costs before you commit to an appointment, though it also means doing your own currency conversion since nothing on the site quotes in Swiss francs.

What stands out

This category ranks dealers on how much paperwork backs a piece up, not on photography, and Lang publishes more of that reasoning than most. Its diamond grading is done in-house by GIA graduate gemologists, with at least three gemologists examining each stone and grading it to GIA standards using GIA master color diamonds for color comparison. The site is upfront that not every ring carries a third-party GIA or EGL lab report: when one exists it is stated on that listing, and when it does not, Lang says so rather than implying otherwise. Gemstone pieces with treatment concerns get the same treatment-disclosure habit, with independent lab reports from AGL, GIA, SGL or other accredited labs where relevant. After a purchase, Lang also emails a point-of-sale report for insurance purposes, arriving as a PDF roughly a week later. It is worth being precise about what that is: an insurance-facing valuation from the seller, not an independent third-party appraisal, which is the more useful document if you ever need to prove a value that has nothing to do with what you paid.

The collection and the aftercare terms

As of this write-up the site lists 343 vintage engagement rings, with the first page of results (sorted newest first) running from $1,950 to $237,500 and a broad middle band in between. A 2020 trade profile of the business described a larger working inventory at the time, roughly 600 engagement rings and 3,500 pieces across the whole catalogue, so treat the collection as one that rotates and narrows rather than a fixed size; what is live on the site today is the number that matters for a purchase decision. That same profile named the current owners as Mark Zimmelman, a third-generation jeweler, and Suzanne Martinez, a jewelry historian and senior gemologist, who by 2020 had run the business for three decades, and credited Martinez with founding the Antique Jewelry University, a free reference site the company maintains for jewelry history and hallmark research.

Lang backs its stock with a real guarantee rather than a marketing line: every vintage piece is inspected by its in-house gemologists and jewelers before sale, missing stones are replaced and manufacturing defects repaired at no charge, and the company asks that you have the piece professionally inspected and cleaned every six months, which it also does free of charge, to catch problems before they cause damage. The one condition worth knowing before you buy is that any work done by another jeweler voids that guarantee, which matters if you are the type to take a ring to a local goldsmith on Bahnhofstrasse for a quick check.

Ring sizing works the same way most dealers with in-house workshops run it: the first sizing is free and takes about two weeks, most rings can be safely sized up or down one full size and sometimes more, but eternity rings with stones running the full circumference, and a handful of especially delicate pieces, cannot be sized at all, and this is noted on the individual listing when it applies. If you buy a ring that needs a bigger adjustment, Lang's practice is to ship it as is first so you can confirm you want to keep it, then have you send it back for the resizing work before it comes to you a second time, which means a purchase like that involves two round trips rather than one. You can still return a ring after it has been sized, minus the cost of the sizing itself.

Ordering from Zurich

Everything ships from the US, so the practical questions are shipping, customs and returns. Domestic FedEx and USPS options do not apply to a Swiss address, but Lang's international shipments go by FedEx International Priority at a flat rate of $110 for shipping, and the same $110 flat rate again if you need to return the piece, on top of any customs charge that applies to a package heading back into the US. Orders above $100,000 fall outside that flat rate and get shipping priced individually by value and destination. Because Switzerland sits outside the EU customs union, expect Swiss import VAT, and quite possibly duty, to be assessed when a US parcel clears customs on arrival: Lang's own policy states plainly that it is not responsible for any local customs or duties and tells buyers to check with their own customs office, so budget for that cost yourself rather than assume the $110 covers it. For pieces old enough to qualify, Lang says it will provide paperwork noting that an item is more than 100 years old, which some countries treat as an antique exception; it is worth asking Swiss customs directly whether that applies before counting on it.

Returns on an online purchase run for 10 days from the date it arrives, for any reason, with a full refund of the purchase price (shipping is not refunded), or you can exchange for store credit within 30 days, after which the sale is final. A piece bought via Affirm financing gets the same 10-day refund window but without the store-credit option. Special or custom orders are excluded from the refund policy entirely and are final sale, which the site does not otherwise define further, so there is no published lead time to quote for anything genuinely bespoke; ask before you commission rather than assume a timeline. If you do return something, Lang says it processes the refund within three days of receiving it back, and aims to resolve any dispute within one to two business days.

Payment runs through major credit cards, PayPal, Affirm financing or bank transfer, with a 3% discount automatically applied if you pay by bank transfer, useful if a wire is more convenient than a card from a Swiss account. Business and phone hours are Monday through Saturday, 10:30 am to 5:30 pm Pacific time, which sits roughly nine hours behind Zurich, so reaching the concierge line means calling in the Swiss evening rather than during a European workday.

Who it suits

Lang suits a Zurich-based buyer whose taste runs to a specific historical period, Victorian filigree or an Art Deco solitaire in particular, and who is comfortable buying from photographs, a video appointment and a documented grading process rather than handling the ring in a shop first. It is less suited to someone who wants to walk out the same day with a ring in hand, since even with fast shipping there is a transatlantic delivery and a possible customs stop before it arrives, and it asks a bit more patience from a buyer who later needs a resize, since that means shipping the ring back to San Francisco rather than to a jeweler around the corner. Set against that is a dealer that has been doing exactly this since 1969, grades its own stock to a published standard, and tells you plainly when a piece lacks a lab report instead of leaving you to assume one exists. For a newcomer to Zurich who wants a genuine antique or vintage ring and is willing to manage the shipping and customs side themselves, it is one of the more thoroughly documented options this category has to offer.
