Diamonds and gemstones

Because every part of your Code by Edge jewellery is personal, we offer you the choice of lab-grown or mined diamonds.

Whichever you choose, you can trust that your diamonds have been sourced with the utmost thought and care, for the planet and the people involved. All the better to help your own message shine bright.

We create jewellery with nods to your culture, your history, the places you have come from and the future you’d like to create. - Donald Edge

Our mined diamonds

Every earth-mined diamond that we use has been sourced safely and fairly through transparent supply chains, adhering to Responsible Jewellery Council Code of Conduct guidelines and the Kimberley Process Certification Scheme. This means preventing the flow of conflict diamonds, supporting mineworkers, their families and communities, and protecting the planet itself from unnecessary harm.

Our lab-grown diamonds

Meanwhile our lab-grown diamonds are created using advanced technology that mirrors natural gemstone formation. Conflict-free, safe to produce and every bit as dazzling as diamonds found in the earth, these incredible jewels are an exciting and sustainable way to wear your heart on your sleeve. Or your wrist, or your finger.

Whichever you choose, you can rest assured that your diamonds will have been sourced with the utmost thought and care, for the planet and the people involved. All the better to help your own message shine bright.

Our gemstones

Like our diamonds, our gemstones are always responsibly sourced. Alongside sustainably mined jewels, we also use hydrothermal gemstones, which are created using the natural convection powers of heat and gravity – just as they are in the earth.

We love our hydrothermal gemstones for their beautiful consistency in colour, and for the double-sided chequerboard cut which brings our necklaces, pendants and earrings alive. They move with you, filter light and shine from every angle.
