Catbird sells a half-millimetre solid gold ring for $74. Jennie Kwon sells a solid gold stacking band for $320. Both are 14ct, both are made in America, both are thin, and both come up in the same conversation whenever someone asks where to buy minimalist fine gold. The conversation treats them as one decision. It is two, with a third underneath: whether an American brand is the right place for a Londoner to spend serious money at all.

Minimalist is a word the trade applies to anything small. It fits Catbird, whose signature ring is a slightly hammered thread of gold. It fits Jennie Kwon less well: the brand's own site describes its rings as having an art deco feel, and its signature Equilibrium setting is pavé diamonds with hand-worked milgrain, which is delicate and also busy. Delicate is not the same as minimal, and that difference decides which one you should buy.

This guide compares Catbird and Jennie Kwon as sources of minimalist fine gold: what each makes, what it costs, who each suits, and the part most roundups skip, which is what happens when you order from London.

In Brief: Catbird (Brooklyn, 2004) is the minimal choice: solid gold made with over 95% recycled gold, a signature 0.5mm Threadbare ring at $74, and a studio of more than 40 jewellers. Jennie Kwon (Los Angeles) is the detailed choice: 14ct gold with diamonds and coloured stones in a deco-influenced style, handmade to order, with a plain stacking band at $320 and most best-selling rings between $645 and $1,998. Both ship to the UK, and both treat international sales as final, with duties and taxes payable by you. Buy Catbird for plain gold, Jennie Kwon for one considered piece, and get your ring size checked by a UK jeweller before you order from either.

What solid means here

Both brands work in solid 14ct gold (14k in American usage), which means gold alloyed all the way through instead of a plating over silver. That puts them in the same category as Mejuri's solid range, and it means the vermeil-versus-solid argument in our Monica Vinader, Mejuri and Missoma comparison applies in its strongest form: solid gold does not need replating. For what carat numbers mean for wear, the gold guide covers 9ct, 18ct and 22ct, and 14ct sits between the first two.

Catbird

Catbird began in 2004 as a multibrand jewellery boutique in Williamsburg, Brooklyn, founded by Rony Vardi, according to WWD. The in-house line followed in 2006, and since 2018 the studio has been in the Brooklyn Navy Yard, home to more than 40 jewellers. A shop first and a maker second explains the catalogue, which reads like a well-edited collection of small personal things: tiny alphabet charms, name necklaces, whisper-thin rings.

The metal is solid gold, which Catbird says is never plated and made with over 95% recycled gold and 95% recycled diamonds. Check the karat on each listing: the brand sells both 10k and 14k pieces, and the Threadbare ring is listed as 14k.

The Threadbare is the ring that justifies the brand. It is 0.5mm wide, slightly hammered, 100% recycled solid 14k yellow gold, and $74. WWD reported that Catbird had sold around 20,000 of them. At that price it is a cheap experiment in wearing solid gold every day, though half a millimetre is very thin and I would want one on my finger for a fortnight before trusting it with a full stack. For how a stack is built and sized, our ring stacking guide covers positioning across pieces from different houses.

Catbird's most famous service will not help you in London. The Forever Bracelet, a permanent bracelet welded on at the wrist since 2017, is an in-store service at Catbird's American shops. If permanent jewellery is the appeal, Astrid & Miyu offers it here.

Price range: the Threadbare is $74, and Catbird organises its ring, necklace and earring shops into under-$300 and under-$500 edits, which tells you where the volume sits.

Best for: plain, thin solid gold at a low entry price. Stacking rings, tiny charms, and gifts where the personal touch matters.

Worth knowing: international orders ship by DHL Express through eShopWorld for $25, and all international sales are final. Duties and taxes are collected at checkout and cannot be refunded by Catbird.

Jennie Kwon

Jennie Kwon was a classical violinist who became a corporate lawyer, and after the birth of her twins started a jewellery business, per her own account. The biography is the sort marketing teams love. The more useful fact is where the work happens: a studio in downtown Los Angeles' jewellery district, where a small team makes every piece by hand.

The house style is deco: rose-cut and baguette diamonds, bezels, milgrain, and the Equilibrium pavé setting that runs through the best-selling rings. Coloured stones turn up throughout, with emeralds, sapphires and opals well represented in the rings collection. The rings come in 14K yellow, rose and white gold, with 18K and platinum available on request.

On sourcing, the brand describes its gold as Fairmined and Fairtrade and its stones as ethically sourced and conflict free. An interview on the Melee trade-show site describes the gold as recycled instead, so ask which applies to the piece you want.

The prices on the first page of the best-selling rings put the centre of gravity between $645 and $1,998. The plain Stacking Band is $320. The Braided Ring is $695, the White Equilibrium Cuff Ring $855, the Diamond Wave Band $875, the 3 Baguette Equilibrium Ring $1,285 and the emerald Lexie Ring $1,998. There is an under-$500 shop, but the brand's identity is the pieces above it.

Jennie Kwon is the better buy if you want one ring with something going on, and the wrong buy if you were looking for plain gold. The plain gold costs $320, more than four times Catbird's Threadbare, and I cannot tell you from the listings whether width and weight explain the gap, so check both before you compare. The brand invites stacking requests: send it the pieces you are considering and it replies with photos, videos and suggestions, which is a real help when you cannot try a ring on.

Catbird also stocks Jennie Kwon designs, Equilibrium rings among them, so the two are not strictly rivals.

Price range: $320 for a plain band, most best-selling rings between $645 and $1,998, and larger diamond pieces higher.

Best for: one considered piece to wear for years. Diamond and coloured-stone rings in a delicate deco style.

Worth knowing: pieces outside Ready to Ship are handmade to order and take up to two weeks. All international orders are final sale, and the recipient bears any import taxes, duties and fees.

What a London buyer needs to know

Returns. Neither brand accepts international returns. Catbird states that it cannot refund the duties and taxes either, and will accept repairs or resizing on jewellery bought from Catbird, so work out what posting a ring to Brooklyn and back would cost before you treat that as a fix. Jennie Kwon's customised, engraved and one-of-a-kind pieces are final sale before geography enters into it.

Ring size. Both sell in US sizes. Wild Fawn's sizing guide puts UK N at US 6.75 and UK P at US 7.5, so a US 7 falls between the two. Have a UK jeweller size you, then check the Catbird sizing guide and the Jennie Kwon guide. With no returns, a wrong size is your problem.

Import charges. Catbird says duties and taxes are charged according to the laws of each country, and for some shipping locations they may be included in the total at checkout. Add them before you compare either brand with a UK price, and compare the total.

Hallmarks. In the UK, gold over 1 gram sold as gold must carry a full hallmark from one of four Assay Offices, and 14ct corresponds to the 585 fineness mark. I can find no sign that either brand has its gold hallmarked in Britain. I am not a lawyer, and how the Act applies to a direct sale from a US website is a question for Trading Standards. One trade guide notes that jewellery sold directly from overseas may never pass through a UK Assay Office, so the purity has not been independently verified in Britain. In practice you are relying on the brand's word, which is a reasonable thing to do with two established makers and a good reason to ask each for the karat in writing.

If the return policy is the dealbreaker

Mejuri and Otiumberg, both covered in earlier guides, sell solid gold with a London presence: Mejuri in the Monica Vinader comparison and Otiumberg alongside Astrid & Miyu and Daisy London. For London-made solid gold, Maya Magal works from London workshops with shops in King's Cross and Islington, and Wild Fawn makes solid 9ct gold in its London studio. Neither is a like-for-like copy of Catbird or Jennie Kwon, but each removes the customs problem and eases the returns one. For looking after solid gold once you own it, our care guide covers what shortens a piece's life.

My recommendations by buyer type

If you want plain thin gold to stack and a low price of entry: Catbird, starting with the Threadbare. Get sized first, because there is no return if the size is wrong.

If you want one ring to wear for years and are happy to pay for detail: Jennie Kwon, in an Equilibrium design. Use the stacking request service before you order, and ask about width, weight and gold sourcing.

If you are buying a gift: neither ring, unless you know the size. A necklace removes the sizing risk that makes a no-returns policy expensive.

If you want the same idea with UK returns and UK-made metal: the British options above. You give up the Brooklyn and Los Angeles names and gain a phone call to somebody in your own time zone.

Minimalist fine gold is a good idea sold by two brands with different definitions of the word. Catbird's definition is the one I would trust to mean small and plain. Jennie Kwon's means small and considered, which is worth more money and a different kind of patience.

Frequently asked questions

Is Catbird real gold?

Yes. Catbird sells solid gold that it says is never plated, made with over 95% recycled gold and 95% recycled diamonds. The brand sells both 10k and 14k pieces, so check the karat on the listing. The Threadbare ring is 14k.

Is Jennie Kwon real gold?

Yes. Jennie Kwon's rings are solid 14K gold in yellow, rose or white, and can be made in 18K gold or platinum on request. The brand describes its gold as Fairmined and Fairtrade, while an interview on the Melee trade-show site calls it recycled, so ask about the piece you want.

Which is cheaper, Catbird or Jennie Kwon?

Catbird is cheaper at the plain end: the Threadbare ring is $74, against $320 for Jennie Kwon's Stacking Band. The listings do not give enough detail on width and weight to say the two are like for like, so compare those before you conclude that one is better value.

Do Catbird and Jennie Kwon ship to the UK?

Yes. Catbird ships internationally by DHL Express through eShopWorld, at $25 on the product pages I checked. Jennie Kwon ships internationally and states that the recipient pays any import taxes, duties and fees. Neither accepts international returns.

Will I pay import duty on jewellery from Catbird or Jennie Kwon?

Expect to pay import charges. Catbird collects duties and taxes at checkout and does not refund them, and Jennie Kwon says the recipient bears them. Compare the total including those charges with a UK price before you buy.

Do Catbird and Jennie Kwon jewellery carry UK hallmarks?

I found no sign that either brand's gold is hallmarked in the UK. UK law requires gold over 1 gram to carry a full hallmark to be sold as gold, subject to exemptions. How that applies to a direct sale from a US website is a question for Trading Standards, so ask each brand for the karat in writing.
