Zoë Kravitz Fronts Jessica McCormack Day Diamonds | Jewels Club

Some celebrity jewellery partnerships are created for a campaign. Others feel as though they were already there.

Zoë Kravitz and Jessica McCormack sit firmly in the second category.

On Jessica McCormack’s current website, Kravitz appears walking through the city carrying flowers, dressed in jeans, sunglasses and a relaxed trench coat. The diamonds are visible, but they are not treated as the centre of a highly polished red-carpet moment. They simply belong within the way she is dressed.

That distinction is important because it captures the idea behind Day Diamonds more effectively than any traditional campaign setting could.

This is not jewellery waiting for an occasion. It is jewellery designed to become part of everyday life.

Why Zoë Kravitz Works

Kravitz became Jessica McCormack’s first brand ambassador in 2024, but the relationship never felt like a sudden alignment.

She had already been wearing the London jeweller’s Gypset earrings, rings and layered diamond pieces for years. Her own approach to style — relaxed, personal and rarely overworked — reflects the way McCormack wants her jewellery to be worn.

There is also a consistency to Kravitz’s jewellery wardrobe. Pieces are mixed, stacked and returned to repeatedly rather than introduced for a single appearance. That gives the partnership credibility.

The campaign is not asking the audience to imagine Kravitz as a Jessica McCormack client. She already is one.

That authenticity gives the imagery its strength. Kravitz does not make the diamonds look less important; she makes them look more wearable.

What Day Diamonds Really Means

Day Diamonds is presented as a collection on the Jessica McCormack website, but it operates as something broader.

It is the central philosophy connecting many of the house’s most recognisable designs, from Gypset earrings and Button Back rings to Georgian Cut-Down settings, Ball n Chain necklaces and diamond bangles.

The idea is simple: diamonds are too precious to remain unworn.

What makes the concept convincing is that wearability is considered within the jewellery itself. Blackened gold gives diamonds a softer, more antique character. Button Back settings sit comfortably against the skin. Hoops, bands and necklaces are designed to be layered with existing pieces rather than worn as a complete matching set.

Traditional techniques remain visible, but the finished jewellery does not feel formal or historical.

That balance between old-world craftsmanship and modern styling has become one of Jessica McCormack’s clearest signatures.

From Special Occasion To Jewellery Wardrobe

The most interesting part of Day Diamonds is not simply that the pieces can be worn during the day. It is the way the concept changes the relationship between value and use.

Fine jewellery has often been presented as something protected by rarity: brought out carefully, worn occasionally and returned to its box. Jessica McCormack takes a different view. The value of a jewel is also found in how completely it becomes part of someone’s life.

That thinking can be seen across the current Day Diamonds edit, which moves from understated diamond pendants and hoop earrings to important rings and a 17-carat diamond necklace.

The carat weight may change, but the styling language remains consistent.

Even the most significant pieces are shown as part of a wardrobe rather than as isolated objects. That is where Kravitz becomes especially relevant. Few people make substantial diamonds look so instinctive.

Some Of Our Favourites

0.40ct Diamond & Blackened Gold Gypset Hoop Earrings — £6,000

If one design explains Day Diamonds, it is probably the Gypset hoop. Round brilliant diamonds are set in blackened gold and suspended from yellow gold hoops, creating a contrast that feels antique, informal and instantly recognisable.

They are designed to stay in rather than wait in a jewellery box, which makes them one of the clearest expressions of the Jessica McCormack philosophy.

Jessica McCormack’s signature Gypset hoops pair round brilliant diamonds with antique-inspired blackened gold and yellow gold hoops.

Georgian Cut-Down 0.25ct Diamond & Blackened Gold Pendant Necklace — £3,500

This pendant distils the Georgian Cut-Down aesthetic into one highly wearable piece. The blackened setting gives the diamond definition without making the necklace feel overly formal, while the fine chain keeps the focus on the stone.

It is an easy starting point for the Day Diamonds look and the kind of necklace that can sit naturally alongside existing chains, charms and inherited jewellery.

Forget Me Knot 0.80ct Diamond White Gold Bangle — £18,000

Inspired by a sailor’s knot, the Forget Me Knot bangle curves around a 0.80-carat round brilliant diamond set in 18-carat white gold.

The design has enough presence to be worn alone but is deliberately streamlined for stacking. It is substantial without becoming rigid, showing how McCormack brings movement and a sense of ease into an important diamond bracelet.

1.21ct Tilted Pear Diamond Button Back Ring — £20,000

The tilted pear demonstrates how a small change in orientation can completely alter the character of a familiar diamond shape.

Set at an angle within McCormack’s Button Back design, the pear-shaped diamond feels less conventional and more personal. It retains the importance of a significant solitaire while avoiding the predictability sometimes associated with one.

0.90ct Diamond Golden Snake Ring — £24,000

Day Diamonds is not only about understatement. The Golden Snake ring introduces character, texture and a subtle sense of danger.

Its coiled gold form is finished with intricate scale detailing, while a marquise-shaped diamond forms the head. It is playful without becoming novelty-led and demonstrates the wider personality within McCormack’s jewellery world.

The Golden Snake ring combines textured yellow gold with a marquise-shaped diamond and sculptural coiled form.

Signature 17ct Diamond Button Back Necklace — £140,000

The Signature Button Back necklace is where the Day Diamonds idea is tested at its most ambitious.

Featuring 17 carats of round diamonds, it has all the presence expected of an important diamond necklace. Yet the individual Button Back settings and flexible construction keep the design feeling relaxed, tactile and surprisingly easy to imagine beyond formal eveningwear.

This is not a quiet piece, but it proves the point: everyday wearability is an attitude, not a limit on scale.

Jessica McCormack’s Signature Button Back necklace brings together 17 carats of diamonds in a flexible, modern setting.

The Jewels Club Take

Day Diamonds works because it is not simply a styling phrase attached to a product edit. It is a clear position on how fine jewellery should fit into modern life.

Jessica McCormack understands that wearability does not mean making jewellery less important. It means considering comfort, proportion, styling and personality with the same seriousness as carat weight and craftsmanship.

Zoë Kravitz gives that idea a convincing face because she does not appear transformed by the jewellery. She remains entirely herself.

That is what makes the campaign feel relevant. It moves diamonds away from the idea of performance and towards personal identity — not jewellery reserved for the life someone imagines, but jewellery made for the life they actually live.
