Precision-Calibrated Green Round Brilliant Diamonds
Our 3.9mm Green Round Brilliant lab grown diamonds are precision calibrated to a +0.04mm tolerance, providing consistent sizing for jewellery making, matching stones, replacement diamonds and bespoke settings. Each diamond is selected for its overall appearance, proportions and colour.
Round Brilliant Cut & Sparkle
The Round Brilliant Cut is renowned for its classic circular shape and exceptional sparkle. Its carefully arranged facets are designed to reflect light and produce an attractive combination of brilliance and fire while showcasing the diamond's green colour.
With its balanced proportions and timeless appearance, the Round Brilliant Cut is a versatile choice for engagement rings, solitaire settings, earrings, pendants and contemporary jewellery designs.
Intense Green Colour & VVS Clarity
These lab grown diamonds feature an Intense Green colour, offering a distinctive alternative to traditional colourless diamonds. Their rich green appearance makes them particularly suitable for statement engagement rings, coloured diamond jewellery, nature-inspired designs and bespoke creations.
With VVS (Very, Very Slightly Included) clarity, inclusions are extremely difficult for a skilled grader to see under 10× magnification, providing a high level of clarity alongside their distinctive green colour.

Top Grade Rough
Our lab grown melee diamonds are created using the High Pressure High Temperature (HPHT) growth process, which replicates the natural conditions deep within the Earth's mantle. This produces exceptional colourless, high-clarity diamonds that require no post-growth treatments. Every diamond offers the same physical, chemical and optical properties as a natural diamond
The Perfect Cut
Every lab grown melee diamond is expertly cut to maximise brilliance, fire and scintillation. Precision calibration ensures each stone matches the required dimensions, with a manufacturing tolerance of just ±0.04 mm, making them ideal for pavé setting, micro-setting, engagement rings, wedding bands, jewellery repairs and fine jewellery manufacturing
