Once is a member of the Responsible Jewellery Council, and works closely with the team there to influence and create a sustainable jewellery ecosystem.
Our obsession with quality permeates all parts of our business. It’s our priority from the way we manage our team and office, to the packaging we use, and the jewellers we partner with.
We do not partner with anyone that does not share our commitment to a sustainable jewellery world.
We support conflict free and ethically sourced jewellery and jewellers. We pay particular attention to understanding the merchant's source of supply by tracking their membership through Responsible Jewellery Council and the Kimberley Process.
This will always be a part of our criteria when partnering with brands and designers.
We only deal directly with the brands listed on the website. Our preference is to foster close relationships with our designers so that we are always privy to all sourcing and sustainability practices. We do not acquire products from third parties.
All certified diamonds come with a GIA certification, which is issued by an accredited independent gemological laboratory.
