Brilliant Round Cut Diamonds

Round Cut Diamond: Timeless Brilliance, Perfected

The round brilliant cut diamond is the most iconic and enduring diamond shape in the world. Known for its unrivalled sparkle, it has become the ultimate symbol of love and commitment. With 58 carefully angled facets designed to optimise light reflection, this cut produces maximum fire and brilliance – a radiance that continues to captivate for centuries.

Round Brilliant Cut Diamonds – A Cut with History

The origins of the round cut trace back hundreds of years, but its true perfection came in 1919, when Marcel Tolkowsky published precise mathematical proportions to achieve the greatest possible brilliance. Since then, the round brilliant has set the global standard, making it the most sought-after choice for engagement rings.

The MDT DESIGN Difference

At MDT DESIGN, every round brilliant cut diamond we source is individually assessed for cut, clarity, colour, and carat to ensure only the finest are chosen. Our jewellers then create settings that enhance its brilliance, whether through classic claw settings or our signature tension set designs.

Each piece is entirely handmade in our Collins Street workshop, giving your diamond the craftsmanship and care it deserves. Backed by our Lifetime Manufacturer’s Warranty and complimentary aftercare, your round brilliant diamond becomes more than a ring – it becomes an heirloom.
