Precision-Calibrated Black Diamonds
Our 4.9mm natural black diamonds are precision calibrated to a tight +0.04mm tolerance, providing consistent sizing for jewellery making, matching stones, replacement stones and bespoke settings. Each diamond is carefully selected for its overall appearance, colour and consistency.
Black Round Brilliant Cut Diamonds
The Round Brilliant Cut combines a classic circular outline with faceted surfaces that complement the distinctive appearance of black diamonds. Unlike colourless diamonds, which are valued for their brilliance and fire, black diamonds are prized for their deep colour, striking contrast and contemporary aesthetic.
Consistent Black Colour
Our natural black diamonds are selected for their consistent dark appearance, making them suitable for matching stones and multi-stone jewellery designs. Their distinctive colour creates a striking contrast when paired with white diamonds, coloured gemstones or precious metals.
Jewellery Making & Repairs
4.9mm Black Round Brilliant natural diamonds are suitable for a wide range of jewellery applications, including rings, earrings, pendants, statement jewellery, replacement stones and bespoke designs.
Whether you're a professional jeweller, designer or sourcing a replacement diamond, our calibrated loose black diamonds provide a consistent and convenient option for stone setting.
Loose Natural Black Diamonds
The Carat Club supplies loose natural black diamonds across a wide range of calibrated sizes, making it easy to source stones for new jewellery, existing settings and repair work.
