About OhMyDiamonds

Oh My Diamonds began with a sparkle. A sparkle in the minds of two young entrepreneurs. With a four-generation legacy of diamond trading, a shared dissatisfaction with the service, pricing, and limited selection retail diamond shoppers were facing, and the desire to work together, we founded Oh My Diamonds. Through our knowledge of the British and international markets, we identified the global issues hampering diamond buyers and chartered out a course to change them.

With experience, passion and drive, we now offer buyers a better experience with Oh My Diamonds. We are passionate about our range of 100% certified diamond jewellery, that is proudly manufactured and hallmarked in Britain, and we hope it shows.

Our team is built by knowledgeable GIA qualified gemmologists, bringing the best to you with our industry awareness and technical expertise. We deliver superior-quality diamond jewellery at great prices by focusing on three core areas:


For far too long, retail diamond buyers have been locked out of the trends, styles, and diamonds enjoyed by only the select few at private showings. Oh My Diamonds changes that by:

  • Opening up our access to 200,000+ diamonds directly to you.
  • Offering the ability to shop a range of diamond jewellery, from anywhere, at any time.
  • Vigorously researching jewellery trends and staying on the cutting edge of style by blending the best of the past with the trends of today.

Our goal is to offer buyers the best price possible on our range of exquisite diamond jewellery. We do this by

  • Eliminating middlemen: We are diamond traders and fine jewellery manufacturers, meaning we can pass along the savings to our clients
  • Transparency: All our products have a clear pricing breakdown, so our clients understand what exactly they are buying and what it costs
  • Bringing an innovative approach to our trade; working with all of our eco-system partners to increase efficiency every step of the way, enabling our clients to enjoy the best and lowest prices possible

Just selling an elegant piece of jewellery isn’t enough for us. We are proud to offer:

  • Free resizing and engraving
  • 30 day, hassle free, money back guarantee
  • Free, insured Royal Mail delivery directly from our London headquarters for domestic buyers and FedEx deliveries for our international customers. Orders feature discrete outer packaging with stunning, beautiful, and elegant, inside gift packaging
