Ingle & Rhode Logo

Ingle & Rhode

London, U.K.

Our story began in 2006, when David Rhode was looking for an engagement ring but couldn’t find a jeweller who could tell him where their diamonds had come from, or the conditions under which their jewellery was produced. The more he looked into the industry, the more compromises he discovered he was being asked to make. From blood diamonds, to dirty gold, to sweatshops and child labour. Together David and his friend Tim Ingle launched Ingle & Rhode in 2007 to offer an ethical alternative to the traditional luxury brands.

Bragaglia Mara

Torrice, Italy

The idea of the secret meaning is at the core of all I make. Since my philosophy studies, my work has always been about mystery and discovery. In the efforts of building a straight line between my inner world and designs, I tripped over a question: were the materials we were using as fair and authentic as the meaning they would have preserved? Beautiful esthetic should come along beautiful ethic. We began questioning our suppliers and learning more about the dynamics behind gold, pearls and gems. Since then, we introduced Fairtrade Gold in Italy and continue to look for the fairest precious materials.

Saskia Shutt Designs

Brussels, Belgium

Sustainability and traceability are the cornerstones of my craft, and when navigating the kaleidoscopic world of responsibly mined gemstones, I approach each selection with the fervour of a child in a sweet shop. The journey of crafting a piece often begins with the discovery of a gem that captivates my imagination – a gem boasting unique colours and shapes that beckon me to translate its story into a bespoke creation.
In essence, while gemstones undeniably take centre stage in my artistic narrative, bespoke jewellery remains the beating heart of my practice. It’s a realm where creativity and personal connection converge, allowing me to transform individual aspirations into enduring works of wearable art.
