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
Everylab 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
