Precision-Calibrated Tapered Baguette Diamonds
Our 3.8mm x 2.5mm Tapered Baguette lab grown diamonds are precision calibrated to a +0.04mm tolerance, providing consistent sizing for jewellery making, matching side stones, replacement diamonds and bespoke settings. Each diamond is carefully selected for its overall appearance, proportions and consistency.
Tapered Baguette Cut & Brilliance
The Tapered Baguette Cut features an elongated shape that gradually narrows towards one end, with clean lines and distinctive step-cut faceting. Its long, parallel facets produce elegant flashes of light rather than the intense sparkle associated with brilliant cuts. The tapered outline makes it particularly well suited to three-stone engagement rings, where the diamonds can sit neatly alongside a larger centre stone.
Colour & Clarity Options
Available in D–E colour with a choice of VVS, VS or SI clarity. VVS offers higher clarity, while VS and SI provide additional options depending on the requirements and budget of your jewellery design. As Tapered Baguette diamonds feature broad, open facets, inclusions may be more noticeable than in brilliant-cut diamonds of a similar clarity grade.
Jewellery Making & Repairs
3.8mm x 2.5mm Tapered Baguette lab grown diamonds are particularly suitable for engagement ring side stones, three-stone settings, earrings, jewellery repairs and bespoke designs.
Whether you're a professional jeweller, designer or sourcing a replacement diamond, our calibrated loose lab grown diamonds provide a consistent and convenient option for stone setting.

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
