"Tea with Maria" and the most talented names of the jewellery world 

Established in Milan in 1967 by Pino Rabolini, Pomellato has already become one of the giants in European high jewellery. A forward-thinking company in its philosophy, Pomellato originally made waves with its prêt-à-porter collections, liberating women to take advantage of luxuriant elegance wherever they where, whatever they were doing. From its classic Re and Regina pendants through to "M'ama non m'ama" and the phenomenally successful Nudo stacking rings, its innovative and colourful use of precious stones makes for cuts that carry a softer shape than other companies, displaying an unquestionably unique style.

Solange Azagury-Partridge's fine jewellery collections blend pop-art immediacy with ancient mysticism - the pieces themselves bearing vigorous energy and bold craftsmanship. From the striking rock-and-roll colours of her enamel pieces to her wildly colourful Poptails cocktail rings, and her collaborations with Swarovski and H&M, there's much to admire here.

Founding the company in 1982, Theo Fennell's eponymous fine jewellery brand has become something of a British treasure in its few decades, with every piece of jewellery and silverware meticulously handcrafted in its workshops above its flagship Fulham store. Classics such as the silver Marmite pot lid or skull rings all come from inspired collections combining artistry and craftsmanship, with one collection inspired entirely by bees, resulting in colourful, idiosyncratic, yet entirely gorgeous pieces. Forever carrying a sketchbook should inspiration take hold, Theo Fennel has ensured that his fine jewellery brand is one full excitement and a very particular variety.

Polish-born Tomasz Donocik is a trailblazer in contemporary jewellery, creating pieces that combine the traditional craft of an artisan with bold and inspired designs that take their cue from literature, architecture, surrealism and even 80s sci-fi. Named UK Jewellery Designer of the Year in 2011, his jewels win awards year after year, including the 2016 Couture Design Awards in Las Vegas for his Stellar earrings, pictured.

London's Hannah Martin founded her very particular fine jewellery and accessory brand in 2005, aiming it at an audience often overlooked by other companies: men. Since then Hannah Martin has also designed collections for women, but regardless of gender, the ethos remains the same. Each fine jewellery piece is imbued with a carefree rock and roll approach, defined by strong lines and an extravagance with an almost cavalier attitude. Every design stems from Martin's firm belief that luxury is something that should have a lasting veracity, which stems from edgy, inventive, and genuinely unique craftsmanship.
