kleine Rheinperle

kleine Rheinperle is a goldsmith's studio in Basel run by the goldsmith couple Marlen and Stefan Wacha, who say they have been making jewelry by hand together for 15 years. The site, published in English, German and French, presents the studio as a Basel goldsmith for special wedding rings and individual jewelry designs. Its signature is the Retina ring, a wedding band that carries a section of the wearer's or partner's retina, and it also makes rings with natural textures and classic plain bands. For couples from abroad, two details stand out: the site is fully in English, and it says Retina rings can be ordered and shipped worldwide without a studio visit.

Retina rings

The Retina®Ring is the studio's own invention, and the homepage calls it "The most personal piece of jewelry in the world". It contains a section of your own retina or that of your loved one. Because the retina is even more distinctive than a fingerprint, the site says, each Retina piece exists only once in the world, and the pattern works as "a secret code that is unknowable for third parties". To an ordinary observer, the pattern looks like a river landscape, roots or a random organic design; only the wearers know where it comes from.

The pattern can be made in two ways: raised, light and highly polished as a classic design, or recessed, dark and matte as an inverted design. The homepage invites couples to have their retina photographed directly at the studio, and offers an animated 3D visualization of the ring beforehand.

The Retina page shows examples in 18 karat yellow gold, 18 karat red gold, 21 karat yellow gold and platinum, some with diamonds set inside a vessel of the pattern. It also says the collection has been shown at exhibitions in Switzerland, Germany, France, Austria, England, Scotland and the United Arab Emirates, and that the veins are designed so they will not wear off over time. Beyond rings, the Retina collection includes pendants, studs, hoops, bangles, watches and cufflinks.

Natural structure rings

The second collection translates patterns from nature into a relief on the ring. Stefan Wacha writes that he uses a CAD program built for jewelry design, with which he can realize any customer request. The page lists sources from synapses in nerve cells and leaf and tree-bark patterns to meteorite craters and lava flows on Mars. All these rings are available in silver, rose gold, white gold, yellow gold or platinum.

The gallery captions show how far this goes: platinum wedding rings with a mountain panorama from a photo the customer brought, lava-flow rings in red gold with diamonds, leaf-vein rings in yellow gold, a footprint ring, a birch-leaf pendant made from a leaf a customer brought in, and special commissions such as a ring engraved with musical notes. Couples with their own image or motif are invited to talk it through with him.

Classic wedding rings

For couples who find the textured rings too rough, the classic collection focuses on clean shapes and the metal itself. The page describes the shine of platinum, the warm hue of red gold, and white gold, which it notes is sometimes worn without rhodium plating and then shows a dark anthracite tone.

The surface section is practical. It explains that high gloss and matte are a matter of taste, that the studio likes an ice-matte finish that looks evenly scratched, and that satin finishes have a softer shimmer. It also warns that every ring changes when worn: a shiny ring becomes slightly duller from small scratches, while a matte ring visually polishes up a little. The deeper a matte finish goes, the longer it lasts. Classic rings are made from one piece of smooth tube; rings with a deeper relief are cast from a wax model. Hammered and milled surfaces are also offered.

Materials and sourcing

The studio works with platinum, yellow, rose, red and white gold, palladium and silver. On the wedding-ring page it says that, as the first goldsmiths in Basel, it has worked with ethically sound gold, platinum and silver since 2015, and that its gold comes from a Swiss refinery certified as a processor of conflict-free gold and other alloys (palladium, silver, copper). It keeps diamonds and colored stones in stock in many sizes, says all its diamonds are conflict-free, and buys other gemstones from guaranteed sustainable sources where possible ("green mining"). These are the studio's own statements; the site links separate pages on sustainability and green mining.

Service and ordering

The wedding-ring pages describe the service in three steps. The studio advises in detail and first makes a non-binding offer "at fairly calculated prices". On request, depending on the design, it produces a photorealistic 3D CAD visualization of the rings in advance, so the couple can be sure of the result. And it accompanies the rings for their whole life: refreshing a matte finish or re-polishing the rings is done free of charge.

Two practical points matter for couples planning from abroad. The homepage asks visitors to make an appointment before coming to the studio, because it is open by prior appointment only. And the Retina page says that a personal consultation is an experience but not a prerequisite: couples who live too far away can contact the studio to learn how to send their retina image and how to determine their ring size, and the studio ships worldwide and insured.

What the site leaves open

• Prices. The site publishes no prices; each couple gets a non-binding offer.
• Lead time. No production time is given for any of the three collections.
• Address. The homepage and ring pages link to a contact page but do not print the studio's address.
• Remote orders outside Retina. Worldwide delivery is described on the Retina page; the site does not say whether natural structure or classic rings can be ordered the same way.

Who it suits

kleine Rheinperle suits couples who want a wedding ring with a personal story built into the metal, whether a retina, a landscape from a photo or a leaf. The English-language site, the worldwide insured shipping for Retina rings and the free lifetime refinishing make it a practical option for couples who live abroad or will not be in Basel for long.

Couples who want a quick, off-the-shelf purchase are less well served: every ring is made to order, the studio is open by appointment only, and neither price nor lead time is published. The first step is a message through the contact page to ask for an offer and a realistic timeline.
