What your piece is made of, why we chose it, and how to keep it well.



Materials · Care · Question

Sterling Silver



Ninety-two and a half parts silver to seven and a half parts copper. The copper gives silver a spine, which is why sterling is the metal for the forms that need structure. It darkens slowly in air and faster in sweat and humidity. Every sterling piece leaves with a clear e-coat that slows the darkening, so it is wiped gently rather than polished with treated cloths; some pieces are finished in rhodium, which reads a shade cooler than bright silver and is meant to.

Gold Vermeil



MYJN vermeil is real 18-karat gold, at least 2.5 microns thick, over sterling silver. It gives the piece its gold colour while keeping a precious-metal base beneath. We add a clear e-coat to help protect the finish. Gold is more resistant to tarnishing than exposed silver, but the finished piece is not immune to changes. Over time, friction can thin the gold at the points of greatest contact, gradually allowing the silver beneath to show. A sudden or uneven change is something we would like to see.

Fine silver



Ninety-nine parts silver or more. Softer and whiter than sterling, used where the Atelier needs a wire to move or a surface to glow rather than hold. Fine silver tarnishes more slowly, because there is less copper in it to react, and it bends more willingly, which is a property and not a fault. A fine-silver piece is worn with a lighter hand and is never squeezed to change its fit.

Solid Gold



Some MYJN pieces are solid 18-karat gold, containing 75% gold throughout, and are named as such on their product pages. There is no applied gold layer to wear through. The alloy can still scratch or change in appearance with use, so wipe it gently and store it separately.

Steel



Stainless steel belongs to the MYJN archive. Earlier pieces used 304 or 316L stainless steel, sometimes called titanium steel in the trade. We moved towards silver and plated brass for the forms and finishes we wanted to develop. Steel still scratches and wears, and a water-resistant metal does not make every part of a piece suitable for swimming. For an archive piece, follow its original material information or ask us for care advice

Brass



Brass, an alloy of copper and zinc, is the metal that lets a first piece cost less without being hollow. Here it is never bare: every brass piece is plated in real silver, 18-karat gold or rhodium, then e-coated, so what meets the skin is the same surface as on the silver pieces. The page always says when a piece is brass, and its care is the care of its finish, never brass polish.

WHAT IS ON THE SURFACE



Our sterling silver, fine silver, vermeil and plated-brass pieces receive a clear e-coat to help protect the finish, and every piece is wiped with an anti-oxidant before it is packed. Some silver pieces also have a rhodium finish, identified on their product pages. We offer additional anti-tarnish treatment and, where suitable, a clear lacquer sealant. These treatments do not make jewellery waterproof or guarantee that sensitive skin will not react. Pearls, stones and horn need their own care.



On Water



We do not describe MYJN jewellery as waterproof or impermeable. Remove it before showering, swimming, hot springs and exercise. Chlorine, salt, personal-care products and prolonged water exposure can affect finishes and other parts of a piece, including thread and elastic. If jewellery gets wet, blot it gently and let it dry fully before storing. The care of a piece includes what holds it together.



WHAT WILL HAPPEN



A piece changes through use. Gold plating can gradually wear thinner at points of contact; silver can darken; protective coatings can wear. Natural pearl, stone and horn can vary in appearance from one piece to another. If a change is sudden, uneven or unfamiliar, or a fitting feels loose, stop trying to clean or adjust it and send us a photograph. We will help you work out what it needs.



HOW A PIECE IS HELD




A jade bead is tougher than the elastic through it; a pearl is softer than the wire it hangs from; an acetate comb is one bonded body with stones seated in it. Hold a piece by its fastening, never by a bead, a stone or a fine wire. Keep thread and elastic out of water and do not stretch them further than putting the piece on requires. Do not keep bending a post or a wire to straighten it; put the piece aside and write. The Antoinette's wire was chosen from five for how it moves; it was not chosen to be reshaped at home.


Sustainably grown

Pearls



Pearls are the house's longest love, and the widest range on the site. Cultured freshwater pearls, from rounds to baroques, matched by hand. Near-round freshwater pearls with the look people associate with Akoya; they remain freshwater pearls, and the page says so. Peacock freshwater pearls, whose green and aubergine lustre is a colour, not an origin. Seawater pearls: Akoya, where a piece names it, and Tahitian, with their dark lights. Mother-of-pearl, the lining of the shell, cut and polished. And crystal pearls, which are made rather than grown, and are named as such wherever they appear. A grown pearl's surface is nacre laid down by a living animal, the most alive and most delicate material on this page: perfume dulls it, sweat etches it, wearing and wiping keeps it.


We source from partners we have worked with long enough to trust with our name. We cannot trace every step between the earth and your hands. What we can do is stay small enough that nothing enters this studio without being seen, held, and chosen by someone who will answer for it.

Ethically Sourced

Jadeite



The jade here is nephrite: Hetian whites, the warm tones of Qiemo, and celadon greens. We choose it for its colour, texture and feel, allowing the variations of the stone to remain. Each product page names the material used. Jade is tough, but the wire, thread, elastic and fittings around it need gentler handling; care for the complete piece.





Natural materials, and cultivated ones, each named as such on its piece

Semi-Precious Stone

Beads

Lapis Lazuli



The lapis here is natural and never dyed, in the grade the trade prizes most: a deep, even blue with only a trace of pyrite gold and calcite white.

Black-lip oyster



The shell of the black-lip oyster, the same oyster that grows the Tahitian pearl, cut and polished for its dark nacre: charcoal, silver and a green that moves as the light does. No two cuts match, and none is dyed. A soft, dry cloth, and nothing else.

Mother of pearl



Mother-of-pearl is the inner lining of the shell, nacre laid down over years and cut flat. Here it is used uncoated, so the shimmer you see is the shell's own. It scratches more easily than stone and dislikes perfume; wipe it, and keep it from hard edges in the pouch.

Red Agate



Red agate is banded chalcedony, warm and faintly translucent, hard enough for daily wear. Our pieces are natural and undyed, cut as cabochons and seated without claws. A barely damp cloth, dried.

Black Agate



lack agate is the same stone in its darkest band, dense and even, with no fillers and no surface treatment. It takes a high polish and keeps it. A barely damp cloth, dried.

We are committed to ensuring all the materials we use meet our standards for environmental responsibility, fair work, and sourcing practices.



Horn and acetate



The combs are cut from natural horn, made of the same keratin as hair and behaving like it: heat warps it and long soaking lifts its layers. The horn patterns are chosen by hand at the house, and the gift combs are washed and polished by hand at the house.



 Acetate is made from cotton and wood pulp, warm in the hand and bright in colour; in the Gardienne, red and black layers are bonded and set with agate, so the body, the teeth and the stones are one object and are cared for as one.


responsibly sourced

Leather

Grain Leather

Suede Leather



Where a piece uses leather, it is full-grain and left uncoated, so it keeps its markings and darkens with wear. Keep it dry, let it breathe, and let it age.

Suede

Vegan Leather



Vegan leather at MYJN is thoughtfully chosen — not just as an alternative, but as a material with its own character. Made without animal products, our vegan leather is smooth, durable, and designed to hold its shape with daily use. It offers a clean, minimal finish and a softer environmental footprint, without compromising on feel or function

Yarns

Textile

Silkworm

Silk

N

atural silk is unmatched in softness, sheen, and drape. Lightweight yet strong, it moves with a fluid elegance and feels cool against the skin. At MYJN, we use high-quality silk selected for its smooth texture and luminous finish — free from synthetic blends. Whether worn or wrapped, it adds a touch of quiet luxury that’s felt instantly.

Cotton

Linen



Linen is effortless by nature — breathable, textured, and quietly refined. Made from flax, it’s one of the oldest and most sustainable textiles in the world. At MYJN, we choose pure linen for its natural strength, airy feel, and lived-in softness that only gets better with time. Cool in summer, timeless year-round — it’s fabric with soul.

 CARE 

The cloth in the box



Every order includes a care cloth; the current edition is Magnolia, a vegan suede that can be used on both sides. Wipe with a clean area and light pressure, keeping the cloth free of grit. Do not scrub to remove a stubborn mark. Treated silver-polishing cloths and silver dips can damage coated or plated finishes. If gentle wiping is not enough, contact us before sending the piece for complimentary general cleaning.

What you see, and what to do



Silver gone dark: tarnish reaching through a worn coat. Wipe with the Magnolia cloth; if it stays, send it in for the free cleaning and, if you wish, the anti-tarnish process. 

Gold looking lighter after years: vermeil wearing as vermeil does. Not a fault. Wear on, wipe gently.  Gold lighter within weeks, or flaking: not normal wear. Stop cleaning it and write with a photograph. 

A white fleck on a chain: the e-coat lifting at a link. Harmless; the anti-tarnish service can re-seal it.

A band bent, a post or clasp loose: wear or a knock. Stop wearing it and write; the Workshop repairs and reshapes.

A mark on the skin: sweat meeting copper, or a sensitivity. Wipe both, keep dry, stop wearing if the skin complains, and ask about the lacquer sealant.

A pearl gone dull: perfume or sweat. Wipe, keep it flat in the pouch, restring when the silk loosens.

A stone loose on a comb: adhesive aged. The Workshop re-seats it.

Horn or jade not matching the photograph: nature.

Services



General cleaning, in the house or by post, free for as long as you own the piece; write first, so the house can tell you what the piece needs. 

An additional anti-tarnish and protectant process, priced, for pieces that live hard lives. A clear lacquer sealant for sensitive skin. 

Repair and reshaping of what can be repaired and reshaped. Replating and vermeil refinishing are not offered: a worn surface will not take a new plate evenly, and a piece replated badly is a worse answer than the truth. 

You do not need to diagnose anything first. Write to help@myjnofficial.com with the piece's name, your order number and a photograph, and the house will tell you what it sees before you send anything.
