Edelsteinkabinett

Edelsteinkabinett is not a ring shop in the usual sense. It's a Swiss online dealer in loose coloured gemstones, mineral specimens and a small line of finished pieces (pendants, bead necklaces), run under the legal name NET Think AG out of Appenzell. If you're planning a custom engagement ring and want something other than a diamond in the setting, this is a place to source the stone itself before handing it to a goldsmith. The company behind it has been on the Swiss commercial register since 1999, though the gemstone shop itself is a newer project: its own site describes the current catalogue as a first collection, still being expanded "in the coming weeks", so treat it as an active, growing operation rather than an old-established boutique.

The catalogue is organised into named collections rather than a flat product grid. The Genesis Collection is built around untreated stones, the Discovery Collection is the entry point for buyers new to coloured gems, and there's a standalone Investment-Grade-Edelsteine category for buyers thinking about resale value alongside beauty. Individual stone types get their own pages: aquamarine, chrysoberyl, demantoid and other garnets, morganite, opal, Paraiba tourmaline, sapphire, emerald, spinel, tanzanite, tsavorite and zircon all appear by name, and tanzanite specifically has its own unheated line, listed simply as "Unerhitzte Tansanite". That's a meaningful distinction in coloured stones: heat treatment is common and usually undisclosed at the bottom end of the market, so a seller willing to separate out and label the untreated stock is doing more disclosure than most.

For an engagement ring specifically, the site has a page on the value of the centre stone and more than one blog post about choosing coloured gems for an engagement or wedding, so this isn't an incidental fit for the category, it's part of how the shop frames itself. The practical path is: pick a loose stone here, then take it to a jeweller (several of whom are listed elsewhere on this site) to be set. That's a different buying process from walking into a Bahnhofstrasse showroom and picking a finished ring, and it suits someone who already knows they want an unusual coloured centre stone and is comfortable managing the setting separately.

What stands out

The seller makes a specific curation claim worth noting: it says it turns away 99 percent of the stock offered to it, keeping only what meets its own standard for character, quality and authenticity. That's their own figure, not an independent audit, but it's a concrete number rather than a vague claim about quality, and every stone is described as personally checked by their own experts before listing. There's also a dedicated transparency page setting out how the company approaches treatment disclosure, for buyers who want to read the policy rather than take it on faith.

Discreet by design

Shipping is free on every order, and orders typically go out within 2-3 business days of payment clearing, arriving the next business day after that through Swiss Post's PostPac Priority service with tracking. Packaging is described as neutral, discreet and sturdy, which matters if you'd rather a valuable delivery not announce itself to a doorman or a shared mailbox, and every shipment is insured to its full value against loss or damage in transit. Above CHF 5,000 the seller says it proactively contacts the buyer to arrange a fully insured courier or personal delivery instead, at the seller's own cost. That's a sensible threshold: ordinary post is fine for a modest stone, a five-figure investment piece gets handled differently.

Ordering as a Zürich buyer

This is where being Swiss-domiciled actually pays off. The seller's own guarantee page states plainly that the contracting party sits in Switzerland, so there are no customs formalities and no unexpected import tax landing on your doorstep, which is exactly the friction a laptop-based order from Germany or the US can otherwise carry. Warranty terms are published too: a two-year statutory warranty runs from receipt of the goods, and as an alternative to a straightforward remedy the terms offer 110 percent of the original purchase price as store credit, valid for two years. Visible defects need to be reported in writing within 5 business days of receiving the item, so it's worth opening and checking a parcel promptly rather than letting it sit.

Two things aren't published, and it's worth saying so rather than guessing. The terms don't set out a change-of-mind return window the way some EU sellers do (Swiss law doesn't require one for a purchase like this, and none is offered here beyond the defect-based warranty), and the payment methods themselves aren't listed by name anywhere in the terms, just described as "the options shown at checkout". If either matters to you, it's worth emailing before you order rather than assuming.

Where it falls short

The whole site, including the terms, the guarantee page and the FAQ, is in German only. There's no English toggle and no mention of English-language support anywhere I could find, which is a real gap for an international or expat buyer who doesn't read German comfortably, and worth planning around (a translator tool will get you through the ordering pages, but a nuanced email exchange about a specific stone is another matter). Contact is by email only, at a ProtonMail address rather than the company's own domain, with a stated aim of replying within 1-2 business days; there's no phone number published. The impressum lists a registered address at a fiduciary firm in Appenzell rather than a shop you could visit, which fits the delivery-only model but means there's genuinely nowhere to walk in. And the "no showroom visit needed" convenience has one exception: the FAQ says the most valuable pieces can only be purchased after a personal, in-person viewing, so the top end of the catalogue doesn't work as a pure remote purchase.

Who it suits, and the verdict

This suits a buyer who already wants a coloured stone rather than a diamond, is comfortable sourcing the centre stone and the setting from two different places, and values a Swiss-domiciled seller for the tax and returns-address reasons the whole online-swiss category exists for. It suits someone reading German, or willing to work through it, more than someone who needs full English support from first contact to delivery. It doesn't suit a buyer who wants to see and hold the stone in person before committing, unless they're shopping at the very top of the range where that's actually offered.

Within those limits, it's a genuinely distinctive listing rather than another Bahnhofstrasse alternative: a specialist in untreated and investment-grade coloured stones, backed by concrete shipping, insurance and warranty terms rather than marketing language alone, and honest enough on its own pages to flag the exception (top-tier pieces need a viewing) rather than blur it. The German-only service and the ProtonMail-only contact channel are the two things to go in with your eyes open about, not reasons to skip it.
