Purajoya Jewelry

Purajoya Jewelry is a small, sustainability-minded label owned and designed by Avital Gur Cusenza, who has run it since 2020, according to her LinkedIn profile, after more than 20 years working with jewelry, as her own about page puts it. The business is legally registered as Gur & Partner GmbH in Unterägeri, canton Zug, which is worth saying plainly for a Zurich-based buyer: this is not a Bahnhofstrasse boutique, or even a Zurich city address at all. It runs as an online shop with a bilingual site, English and German, and no walk-in showroom. That matters less than it might sound, because the way Purajoya actually works for an engagement or partner ring is by commission rather than by browsing a case of finished pieces, wherever the buyer happens to be.

The name itself is a small piece of branding worth knowing: Purajoya combines the idea of pure joy with the Spanish word joya, meaning jewel or jewelry, and the P and J of the logo are drawn as two hearts. The everyday catalog, the part you can actually add to a cart, is earrings, necklaces, bracelets and pendants in silver, gold vermeil and a house alloy the site calls Premiumsilver, at 960 fineness rather than the usual 925, plus pearls, mother of pearl, rose quartz, pink opal and rock crystal. A dedicated bridal jewelry category exists, but it holds the same kind of pieces (pendants and earrings styled for a wedding day) rather than rings, so anyone expecting a bridal ring case there will be disappointed by the category name.

What you get for a ring

Rings sit outside the regular shop entirely. Purajoya's "gold plating and repair" page states plainly that it will "make new jewelry on demand, e.g. recreate a ring with gemstones and diamonds according to your ideas," and a separate page on custom partner rings talks through options in gold, silver or diamonds, built to the couple's own wishes. This is the route to an engagement or partner ring here: a conversation, not a product page. The process the site describes runs in three steps, contact, a free estimate, then shipping by mail, and it can also be arranged in person. The site states you can bring a piece to Unterägeri (Zug) or to Obfelden (Zürich), or send it by post, and separately confirms that "the jewelry can be delivered and collected in person," with advance contact to arrange a personal handover. Obfelden sits in the Affoltern district of canton Zürich, the same corner of the canton where, according to a profile in the local Affoltern Anzeiger newspaper, Avital Gur Cusenza actually lives, with her designs made up by specialists in the surrounding Knonaueramt region. None of that is a Zurich city consultation, but it is a genuine, sourced answer to where the physical side of this happens, rather than an assumption.

Because a ring is quoted individually, Purajoya does not publish a price for one. What it does publish are prices for its adjacent renewal and repair work, which gives a rough sense of the shop's price floor: repairs and modifications from CHF 39, silver renewal from CHF 49, and gold renewal from CHF 99, with a typical turnaround of 3 to 4 weeks for that kind of job. The site does not state a separate turnaround for a custom ring commission, so that is a question to raise at the estimate stage rather than something we can quote here. Payment on the renewal and repair side runs by bank transfer before work starts; whether a bespoke ring commission follows an identical schedule is not spelled out, so confirm it before you commit anything.

What stands out

Two things separate Purajoya from a plain fashion-jewelry seller that happens to also do repairs. The first is genuine, if unaudited, sustainability positioning: the site describes its Premiumsilver line as 100 percent recycled, its packaging as recycled material, and its production partners as smaller operations chosen for fair wages and working conditions. None of that is backed on the pages we read by a named third-party certification such as the Responsible Jewellery Council, Fairtrade Gold or a B Corp badge, so treat it as Purajoya's own account of its supply chain rather than an independently audited one, and ask for documentation before it factors into a deposit, exactly as this category's own listing criteria suggest.

The second is that Purajoya writes like a business that actually understands lab-grown diamonds rather than one bolting the phrase onto a listing. Its FAQ page and a dedicated "8 facts about lab-grown diamonds" article explain that lab-grown stones have been produced since the 1950s, share the same chemical, physical and optical properties as mined diamonds, and are graded on the same 4Cs, color, cut, clarity and carat. The same article states that lab-grown production is "guaranteed to be conflict-free," which again is Purajoya's own claim rather than something the page backs with a lab certificate or an independent standard, and should be read that way. Still, offering this kind of explainer content at all, alongside a working ring-sizing guide, suggests a business that would talk a customer through the lab-grown option properly at the estimate stage rather than just quoting a number.

Gold plating is one area with genuine, if slightly confusing, published detail: the FAQ describes standard plating as 3 to 5 microns of 24 carat gold, while the renewal service separately offers what it calls a "royal class" tier at 7 microns, so the thickness on offer depends on which service you're booking, worth clarifying up front. Reviews back the reputation up with real numbers rather than just marketing copy: Trustindex lists 113 reviews for Purajoya at a 5.0 average, split between Google and ProvenExpert, and search results in mid-2026 show an active Instagram presence and recent blog activity, with nothing suggesting the business has closed, changed hands or gone quiet.

How it's organised and how it compares

The site itself is a fairly standard WooCommerce shop for the ready-made pieces, filterable by category, with the ring and commission side handled through separate content pages (gold plating and repair, and a specific partner-rings page) rather than a shop listing. That is a very different shape to a dedicated lab-grown diamond retailer that lets a buyer pick a shape, a carat and a setting and check out immediately. Purajoya asks for a conversation first. For someone who already knows exactly what stone and setting they want and would rather not wait for an estimate, that is slower. For someone who has an heirloom piece, perhaps a parent's or grandparent's gold, and wants it melted down and reworked into a partner ring with a lab-grown stone added, it is closer to what they are actually looking for, and it is a service the bigger specialist retailers generally do not offer at all.

Returns and warranty terms are published clearly for the parts of the business they cover. Stock jewelry can be returned within 14 days of receipt if it is unworn and in its original packaging, with the refund following once the return is checked; new jewelry carries a 6-month warranty excluding loss, customer-caused damage, normal wear and clearance items. The terms explicitly exclude jewelry services, which almost certainly covers a bespoke ring commission, from the standard 14-day withdrawal right, so a custom order should not be assumed to be returnable on the same terms as an earring bought off the shelf. Delivery itself is Switzerland only: the site states shipping is free within the country and does not offer international delivery at all, with express delivery inside Switzerland available at a flat CHF 20. For an expat buyer that is fine as long as you have a Swiss address to receive the piece, but it is worth flagging if you are likely to move abroad before a repair or a commissioned ring is finished, since the site gives no indication it will ship a completed piece outside the country.

Who it suits and the verdict

This suits an international buyer in or around Zurich who wants a partner or engagement ring built to a brief rather than picked from a case, particularly one who has family gold to reuse or wants to weigh a lab-grown stone against a mined one with someone who can actually explain the difference. It suits someone comfortable communicating in English by phone, WhatsApp or email and content to wait through an estimate and a multi-week build rather than walking out with a ring the same day. It suits less well a buyer who wants to see a finished engagement ring in a display case before committing, or who needs firm ring pricing up front, since none is published.

The caveats here are genuine but minor set against what the business gets right: no walk-in Zurich shopfront, no published ring price, and sustainability claims that are Purajoya's own rather than third-party certified. Against that sits a real, working commission process with a published contact route, a documented in-person handover option in canton Zürich as well as canton Zug, clear return and warranty terms for its stock jewelry, a solid public review record, and a level of lab-grown diamond literacy on its own pages that a lot of small jewelers do not bother with. For a buyer who wants a ring made rather than bought, that combination earns Purajoya its place on this list.
