Lab-grown diamonds

Lab-grown diamonds are visually, chemically, and physically identical to mined diamonds. Starting life as a small diamond seed, they are placed under High-Pressure, High Temperature (HPHT), a treatment that simulates the geological conditions of natural diamond creation, but only produces a fifth of the carbon emissions of mined diamonds.

After a few weeks, a rough diamond is grown, which is then cut and polished like any other diamond, ready to find its place in a piece of ethical fine jewellery.

Not only are lab-grown diamonds 100% certified and identical to mined diamonds, they are sustainable, conflict-free and significantly less harmful to the environment too.

Recycled gold

Our metal suppliers purchase pre-loved gold in the form of unwanted jewellery and jewellery processing elements. This 100% recycled precious metal is then refined to make mill products such as casting grain.

Our suppliers are SCS (Scientific Certification Systems) Certified, meaning they hold the credentials for the responsible sourcing of precious metals.

Jewellery casting is an art form that has existed for thousands of years. Since we discovered how to melt metal, artisans have been pouring molten gold into different moulds. The MATILDE artisan jewellers keep this tradition as beautifully sustainable as possible using 100% recycled gold.
