The New Street Letter

A monthly window onto the New Street showroom, the brands we carry, and the conversations behind the pieces.

From the showroom

Birmingham has always known how to wait.

For two decades, this city carried its own sense of what fine jewellery should feel like: unhurried, intentional, made to last. When Mappin & Webb returned to New Street in December 2025, it was not an arrival so much as a recognition. The craft was already here. The heritage was always here.

This letter is our monthly window into the showroom. New arrivals, the stories behind the pieces, conversations with the makers and the brands we carry. An occasional lesson in what a hallmark actually says. An invitation, now and then, to join us for an evening.

We do not rush these things. Neither should you.

Welcome to The New Street Letter.

The Hermione

On oval diamonds, warm gold, and the language of modern engagements.

Mappin & Webb Hermione 18ct yellow gold oval cut diamond engagement ring
Mappin & Webb Hermione · 18ct yellow gold · 0.75cttw oval cut diamond

An oval-cut diamond, elongated and brilliant, flatters the hand in a way that rounds and cushions do not. A cut with a long history, first developed in the 1960s by master cutter Lazare Kaplan. Its current moment belongs to couples reaching for a stone that feels personal rather than prescribed; timeless rather than trended.

The Mappin & Webb Hermione is built around this understanding.

“Yellow gold ages into itself. It develops a patina that marks a life worn, rather than a surface preserved.” On the choice of metal

Eighteen carat yellow gold. The choice of metal here is not incidental. For much of the past two decades, platinum and white gold dominated the bridal vocabulary; they read as modern, clean, minimal. What has shifted is the appetite for warmth. Yellow gold, the colour of the craft from its earliest origins, carries a quality that cooler metals cannot. Set against the cool brilliance of 0.75 carats of oval-cut diamonds, the yellow gold of the Hermione works as a counterpoint, lending the piece a richness that is wholly its own.

The workmanship is Mappin & Webb's own. The setting is executed with the precision that has defined the in-house workshop for over two centuries: prongs that hold without crowding, a band proportion calibrated so the stone reads as the uncontested centre, no decorative element that exists for its own sake. Restraint, here, is the signature.

£6,000 A piece to be seen in context, to be held and considered. Available to view privately at our New Street showroom.


Brand spotlight

Roberto Coin

Five questions with Eleanor Wright, Roberto Coin Brand Ambassador, Birmingham.

Tell us about the hidden ruby. Every Roberto Coin piece carries one, but most guests don't know until you tell them.

Eleanor WrightThis is usually the moment in a conversation when everything changes. Roberto Coin set a ruby inside every piece he created from the beginning. Not visible, not displayed: set against the skin, touching the wearer and hidden from the world. His reasoning was rooted in an old Italian superstition that rubies confer good health and good fortune on the person who wears them. What he did was take that belief seriously, and make it permanent. So when you purchase a Roberto Coin piece, you are carrying something inside it that the house placed there for you. A talisman, entirely private.

02

The Venetian Princess collection is one of your most recognisable lines. What makes it endure?

Eleanor WrightThe Venetian Princess begins with a very specific diamond-cut pattern applied to the gold itself: a series of tiny squares worked into the surface so that the metal catches and releases light the way a faceted stone does. It was an innovation when Roberto Coin introduced it, and no other house has replicated the exact geometry. The piece I return guests' attention to most often is the Venetian Princess sapphire pendant pictured above. It is a piece for everyday wear that never looks like it is trying to be anything other than exceptional.

03

For someone buying their first Roberto Coin piece, where would you direct them?

Eleanor WrightTo something they will wear. That is always the starting point. Roberto Coin is not a jewel-case brand; it is meant to be worn, to touch the skin, to travel with you. For a first piece, I usually suggest looking at the core collections rather than the more elaborate statement lines, finding the piece you would reach for most mornings without thinking about it. The hidden ruby will be there regardless. In time, that comes to feel rather important.

A David Yurman Chevron necklace worn with a dark suit

David Yurman Chevron, 2026

House feature

David Yurman

David Yurman was founded in 1980 in New York by the sculptor David Yurman and his wife Sybil. The signature is the cable: a twisted helix of precious metal that has become the brand's most recognisable form. The Chevron collection brings that conviction to a graphic, contemporary register. Pieces designed to be worn, layered, and lived in.

A selection from the Chevron collection is on display at the New Street showroom this season, including sterling silver and pavé diamond pendants from £1,950.

From the bespoke bench

A stone with three generations behind it.

Jeweller's sketchbook open to oval-cut sapphire ring design elevations on a dark walnut workbench
The commission in progress.

The brief was precise in feeling if not in dimension. An oval sapphire, mid-century, of uncertain provenance but certain history: three generations of the client's family had held it. The previous setting no longer suited its bearer. The request was not to modernise the stone, which would have been a misreading, but to set it in something that felt as though it had always been its rightful home.

The first conversation was about listening rather than proposing. When a client brings a stone with this kind of history, the temptation is to meet the weight of the brief with elaboration: to add, to complement, to demonstrate. The showroom team's instinct, honed through many such commissions, was the opposite. The sapphire was the piece. Everything else was architecture in service of it.

Yellow gold emerged not as a trend reference but as a material logic. The sapphire, a deep cornflower blue, has a warmth that white metals counteract rather than complement. Yellow gold, by contrast, does something almost alchemical: it deepens the perceived saturation of the stone, pulls the blue slightly towards violet, gives the whole assembly a cohesion that reads as inevitable rather than designed. The client had not considered yellow gold. By the end of the conversation, she could not imagine anything else.

The technical question was the setting. A sapphire of this age and this cut, transitioned through multiple earlier settings, requires examination before any work begins. The team assessed the stone for existing stress fractures, considered the prong geometry that would secure it without placing undue pressure on its girdle, and proposed a claw setting with six points rather than four: a small distinction, but one that distributes the holding force more evenly and reduces the risk of movement in daily wear.

The sketch took two iterations. The finished piece, in 18ct yellow gold, was collected six weeks later.

From the case

A note on hallmarks.

What the mark on your piece actually tells you.

Every piece of gold, silver, platinum, or palladium sold in the United Kingdom above a certain weight must carry a hallmark. This is not a formality. It is a guarantee, independently verified, of exactly what you are holding.

A UK hallmark has four components, each punched into the metal by a licensed assay office.

I

The sponsor's mark

The initials or symbol of the maker or importer who submitted the piece for testing. This is the manufacturer's signature in the most literal sense.

II

The fineness mark

A numerical figure indicating the precious metal content. For gold, 750 means 18 carat (seventy-five parts gold per thousand). 585 means 14 carat. 375 means 9 carat. The number does not lie.

III

The assay office mark

The symbol of the office that tested and struck the hallmark. London carries a leopard's head. Edinburgh carries a castle. Sheffield carries a rose. Birmingham carries an anchor.

IV

The date letter

A single letter in a specific typeface, changed annually, denoting the year in which the hallmark was struck. For collectors and researchers, this is often the most useful mark of all.

The Birmingham anchor is worth a word. The Birmingham Assay Office was established in 1773, making it the second-oldest in the United Kingdom. Its founding was championed by Matthew Boulton, the industrialist and friend of James Watt, who understood that Birmingham's growing jewellery trade needed a local testing authority rather than making the long journey to London or Chester. The anchor has marked Birmingham-assayed pieces ever since.

Every piece in our showroom carries a hallmark. We are always happy to walk you through what yours says.
