1. Lorenz Bäumer. Chanel and Louis Vuitton have both benefited from the extraordinary talents of the engineering-graduate-cum-jewellery-designer, who set off on his own with the 2011 launch of his Place Vendôme boutique. His twin passions for architecture and the sea find expression in clean-lined designs that showcase the intrinsic beauty of deeply coloured stones.
2. Glenn Spiro. The Christie’s alum is known for his deft eye – a knack that’s served him well as the high-jewellery-world’s go-to guy when it comes to the conception of one-off, couture items. Spiro considers each stone’s innate colour and shape to create timeless specimens newly in reach of the public: his G Collection is sold exclusively at London’s Harrods.
3. Tito Pedrini. Following stints at Christie’s and Sotheby’s, the steely-eyed gemmologist is known for his work with exceptionally rare coloured stones. Burma rubies, Colombian emeralds or ceylon pink sapphires figure into eye-popping pieces with unconventional cuts that have caught the discerning eye of Hollywood’s reigning A-listers.
4. Nirav Modi. There’s no stopping this third-generation Indian diamantaire, who after considerable success in his native India just unveiled a third boutique on NYC’s swish Madison Avenue. Taking inspiration from nature and great artists like Monet, each of Modi’s intricate pieces – created with some of the rarest gems on the planet – takes months to realise.
