Led by Glenn Spiro and his son Joe, the House of ‘G’ goes by a single initial as in our business privacy is key. What G does may be understood best in three dimensions. Most issued as one-of-a- kind creations and limited collections, the private atelier creates small treasures that reframe sought-after historical gemstones in modern designs.

In their appointment-only London atelier, the former studio of fashion designer Sir Norman Hartnell, G combine exquisitely detailed settings with an eyewatering selection of unique stones. A couture piece from the G atelier can be years in the making and their technical mastery has gained a cult following of collectors.

G is renowned as having an unconventional approach to the Haute Joaillerie world, but it’s the risks they take in a realm dominated by old luxury marques and multigenerational businesses, that truly set them apart. The house has a non-conformist attitude to precious gemstones – they attempt the impossible and dream up imaginative designs that have never been done before. The resulting jewellery turns heads for all the right reasons, commanding attention for their originality and confidence that they embody.

“We don’t make what people want; we make what we love – and if they love it, then great,” Glenn says. “If not, we’ll keep it in the safe until the right person walks through the door.”
