Product Highlights

Brand Values


Ethics & Sustainability Overview

Ethica only uses lab-created diamonds and gemstone jewellery. They only partner with diamond growers that are sustainable, and efficient and do no harm to animals, habitats or ecosystems. There are no humanitarian concerns associated with the diamonds or gemstones and high standards of health and safety are in place in the production areas, together with fair pay and good working conditions. In addition, the labs themselves have not been planted in environmentally sensitive or otherwise protected lands. They only use Fairtrade or partly recycled gold and are working towards all precious metals being fully sustainable in the future.

Sourcing & Supplier Transparency Information

Ethica work with a handful of lab-grown diamond suppliers around the world that have an innovative approach to growing diamonds, meaning they monitor their energy consumption and look to offset this in various different ways. Some growers they work with are already working with renewable energy. The patented Ethica Diamond is sourced from a single origin, it’s currently the only manufacturer of this product in the world.
Ethica works with manufacturers that use SCS certified 100% recycled or Fairtrade Gold and fair mined Platinum from a single source mine.
Most of the materials carry third-party certification, where certification isn’t available they are working with suppliers whom they have long-standing trustworthy relationships with.
