I personally find one of the most exciting things about modern jewellery is the innovative and rule-breaking way designers are using stones, with jewellers even at the most commercial end of the market choosing custom cuts and more unusual gemstones. At designer level, it seems there's almost literally no limits to how gems are used - rough stones are as valued as glittering diamonds, stones are set at all angles and into all materials. The two designers I've picked are experimental without being 'gimmicky', producing pieces that reflect an unconventional attitude to what make a stone precious and how they are used.
Kimberly McDonald 
I adore Kimberly's work, fusing the most beautiful rough stones and geodes with absolute luxury. Each piece contains stones that look as though you've picked them off the beach and tumbled them yourself, but raised to stunning heights with soft, fluid gold and studded diamonds. Diamonds and semi-precious stones are the jewellery equivalent of a high/low wardrobe style, that perfect mix of scruffy vintage tee with designer jacket. Pieces like these will never look anything but expensive, but have so much more personality and life than traditional precious-stone fine jewellery.
Jayce Wong
Jayce Wong is a trained gemologist, and has a particular passion which may well be genuinely unique in the industry. Fascinated by the natural fluorescence of gems, she creates deceptively simple cocktail and stacking rings which reveal their incredible properties when viewed under light (below). She also offers a new twist on Stephen Webster's much-copied 'crystal haze' technique, placing
rutilated quartz over black chalcedony, creating a totally different look and adding depth and definition to an already intriguing stone. A chunky stone cocktail ring will never be out of fashion, and
Jayce offers a thoroughly modern - and incredibly clever -take on the style.

NB. The title of this blog is pinched from a Sunday Times Style article from a number of years ago (mentioned in my last blog), which featured Pippa Small, Stephen Webster and Solange Azagury-Partridge as the 'new guard' of jewellers. Incidentally, Jayce Wong's range is called A New Stone Age - I wonder if she read the same article?
