Adiamor

Adiamor is a US-based diamond and engagement ring seller run out of Los Angeles, the kind of retailer built entirely around shipping a ring to your door rather than inviting you into a showroom. For a Zurich address, that changes the shopping experience in a specific way worth understanding before you start browsing its catalog of over 200,000 GIA-certified diamonds.

What you get

The site works like a diamond marketplace crossed with a ring configurator. You search loose stones by shape, round, princess, cushion, oval, emerald, pear, marquise, heart, radiant and asscher are all represented, filter by cut, color, clarity and price, then mount your pick into one of Adiamor's own engagement ring settings or order it loose. The company's own pages describe manufacturing offices in the historic jewelry district of downtown Los Angeles, and the same line turns up across its social channels often enough that it reads as a genuine operational detail rather than marketing filler. Adiamor says it has sold online since 1998 on both its About page and its In the Media page, though its FAQ separately puts the figure at 1999, a small inconsistency on the company's own site worth flagging rather than a date I would build an argument around.

The $1,500 minimum, in practice

Here is the detail that matters most for a Swiss buyer. Adiamor's shipping policy sets a minimum order value of $1,500 for any purchase shipped outside the US and Canada, and international orders ship free via FedEx International Priority. Below that $1,500 line, the international shipping option simply is not offered, so anyone after a smaller center stone, a plain gold band, or anything else that comes in under that threshold will not be able to have it sent to Zurich at all, no matter how good the price looks in the catalog. Above that line, the policy quotes an estimated transit time of 2 business days once the parcel leaves Los Angeles, plus whatever customs clearance adds on the Swiss side. FedEx International Priority is a tracked, name-brand courier service, not a generic postal option, which is one less thing to worry about when the parcel is carrying a diamond.

Duties, VAT and the fine print

This is where Adiamor is more upfront than most US sellers shipping this category abroad. Its shipping policy publishes a country-by-country reference table of VAT rates, and Switzerland is on it at 8%. The policy states plainly that customers, not Adiamor, are responsible for all duties, VAT, taxes, broker fees and surcharges, collected in the destination country's currency on arrival, and that these charges are non-refundable even if the item is later returned. It also reserves the right to refuse shipment to certain countries (standard language for a jeweler moving stones internationally) and requires an adult signature, 18 or older, on delivery. None of this is unusual for a US-based seller shipping abroad, but naming the actual Swiss VAT rate by country, rather than hiding behind a generic "customs may apply" line, makes it easier to work out the real landed cost before ordering rather than after the FedEx invoice arrives.

Returns, resizing and the warranty

Adiamor backs its rings with a 30-day return policy: unworn items sent back to its Los Angeles facility within 30 days of shipping qualify for a refund, replacement or exchange, and the company says refunds are typically processed within 4 business days of the return arriving. The catch for a Swiss buyer is what that policy does not undo: the duties and VAT already collected at delivery are non-refundable, so returning a ring still leaves you out whatever Swiss customs charged on the way in. Adiamor's FAQ also points international shoppers to a separate "Other International Shipment Information" section for full return terms outside the US and Canada, and I was not able to read that section directly, so treat the 30-day window above as the general rule rather than a guarantee of identical terms for every country.

Every ring also carries a free lifetime manufacturing warranty, and Adiamor separately offers free ring resizing for the first 90 days from the original shipment date. That resizing window is a genuine point in the site's favor for someone newly settled in Zurich and still adjusting to a ring that fit differently a season earlier, though using it means shipping the ring back to Los Angeles rather than walking it into a local shop, since Adiamor has no Swiss service point. Sending a ring back for warranty maintenance work more generally comes with what the policy calls "a nominal shipping fee" without stating an amount, so budget a small unknown rather than assuming it is free. Engraved rings stay covered by the same 30-day return window, though the engraving charge itself, a flat $30 per ring, is excluded from any refund. For buyers who want cover against loss, theft or damage rather than just manufacturing defects, Adiamor also offers an optional paid plan through Jewelers Mutual, priced against the value of the specific purchase rather than a flat rate, so there is no single figure to quote beyond what the site itself calculates once you enter your ring's price.

How it compares, and who it suits

Against the in-person Bahnhofstrasse houses and the Swiss-registered online sellers covered in their own category on this site, Adiamor trades same-country VAT and a walk-in consultation for a much larger stone inventory and US pricing in dollars. It will not suit someone who wants to try rings on in person and leave with one the same day, and it will not suit a buyer whose order sits under the $1,500 international minimum. It does suit someone comfortable choosing a certified stone from photos and a grading report, who wants a bigger selection than a Zurich boutique can hold, and who has worked out the 8% VAT plus broker fees ahead of time instead of being surprised by them at the door.

Verdict

For an order over the $1,500 threshold, Adiamor is a solid pick precisely because it states the real numbers upfront: the minimum, the FedEx routing, the Swiss VAT reference rate, the 30-day return window and the fact that duties are non-refundable. Independent reports from past customers online line up with the same $1,500 threshold, and the retailer carries a strong reputation, with 268 Yelp reviews averaging 4.7 stars as of this year. The free lifetime warranty and the 90-day resizing window add real after-sales value for someone settling into life in Zurich, even where using either means one more parcel crossing the Atlantic.
