Based in London, we are disrupting the global fine jewellery marketplace. Once is passionate about creating the most comprehensive and enjoyable online fine jewellery experience ever.
The fine jewellery experience can be a complicated, intimidating and time-consuming one for many.
For designers, it has become increasingly difficult to compete with fast fashion.
We respect the integrity of fine jewellery and its unique makers, while giving her a real chance at being seen and worn by people around the world.
Who we are
An experienced eye for fine jewellery meets technology and innovation. Our wider team has worked with the likes of De Beers, Cartier, Bulgari and Net-a-Porter.
Chief Executive Officer
Shezan has started, ran and sold three businesses across a variety of sectors, including media and advertising, renewable energy and financial technology. The common thread running through all these ventures is using technology to solve problems at scale for consumers and businesses.
Vishal has extensive exposure to the jewellery sector. He has managed one of the world’s largest diamond companies for over 15 years, and worked with leading global brands and retailers. He is also a certified GIA Gemologist.
We are the world’s first online luxury marketplace dedicated to fine jewellery, and nothing else. This is a new world for many, so here’s our promise to you.
Secure shipping & returns
All our deliveries are made by a trusted, registered courier. We take the security of your delivery seriously and require a signature on delivery. For your peace of mind, we’ve made sure that every purchase with Once comes with free, door-to-door, express courier shipping for delivery and returns. Learn more in our Help & Information section.
Our products are fully insured for loss or damages from the time you place your order until it reaches you. If for some reason, there is a problem with your product due to a defect, and it cannot be repaired or replaced, you are entitled to a full refund for up to six months from the purchase date.
If you choose to return your product, the package will also be fully insured during the return.
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.
Once was founded on principles of diversity, integrity and accountability. We believe economic growth can, and must, be achieved with social and environmental responsibility.
We are a proud member of the Responsible Jewellery Council. By joining this sustainability leadership initiative, Once commits to take sustainability leadership to the next level.
