Diamonds are meant to be a girl's best friend. On this, if nothing else, Kate Moss runs with the crowd. 

The world's most famous supermodel has teamed up with Messika to create the Messika by Kate Moss collection. 

And that's not all: our roundup includes pieces from Phillips Flawless, Boucheron and Harry Winston.

We'll keep this article updated with our favourite launches over the remainder of the year. 

It's time to put those holiday plans on ice...

Messika

Messika by Kate Moss

Messika already had pretty serious star appeal. Having Beyoncé as one of your biggest fans will do that for a brand.

But now, the world’s most famous model is also on board. Kate Moss has teamed up with Messika for its latest high jewellery collection.

More than simply a face for the campaign, Moss is the co-designer alongside the company founder Valerie Messika.

The two met serendipitously at The Ritz last year, and after bonding over a passion for high jewellery, the end result was the Messika by Kate Moss collection.

Moss was heavily involved in the creative process – she explains: “I don’t like rules; I like breaking them. There weren’t any limitations set by the design team at Messika, which I loved; I had freedom to create something I really love.”

The inspiration from the collection was from Kate’s own jewellery box – pieces collected over the years from different cultures and eras, especially the 1920s and 1970s.

Phillips Flawless

Shaun Leane from Phillips Flawless

Last month, Phillips launched Flawless, a new online destination selling high jewellery for immediate purchase.

The brand has hit the ground running with a showcase of 12 creations by visionary jewellery designer Shaun Leane.

The collection includes Leane’s most iconic fine and high jewellery designs, as well as new bespoke pieces, created to mark the 21st anniversary of the House of Shaun Leane.

The inaugural offering on Flawless also includes jewels by the likes of Cartier, Chaumet, Mauboussin, Tiffany & Co, and Van Cleef & Arpels.

Boucheron

Boucheron Double motif Serpent Bohème

This Autumn, Boucheron is extending its iconic Serpent Bohème collection.

The latest additions include cascading pendant earrings formed by a graceful flow of diamond pavé motifs; a dramatic double ring with diamonds spanning the entire hand; and this pared-back double motif ring.

In the case of the latter, two asymmetrical diamond-paved drops are surrounded by gold beads. The ring loops underneath the finger resulting in the effect of the drops appearing to float magically either side.

Harry Winston

Harry Winston Kaleidoscope Collection

Harry Winston’s latest collection was inspired by a limited-edition jewelled piece of art called the Ultimate Kaleidoscope, which the house created back in the 1990s.

It was a visual tribute to the brilliance of a diamond – the refraction of light and colour, a parallel to its many facets.

Nearly 30 years later, Harry Winston has taken this theme and run with it across an entire collection.

Although there are 32 pendants in multifarious colours and configurations, our favourite piece is actually this monochrome timepiece – pure class.
