Lab-grown diamond quality
D–F colour · VS1 clarity or better
Every lab-grown diamond is D–F colour and VS1 clarity or better. Round brilliant lab-grown diamonds can receive a formal cut grade; fancy shapes are assessed through their proportions, polish, symmetry and overall make. Any piece whose centre stone, on its own, weighs 1.00ct or more includes an individual IGI grading report as standard. Total carat weight does not count towards this.
Straight lines would miss the point. Allegra changes direction across the finger, cutting a crisp zigzag in gold and following every turn with round lab-grown diamonds. It brings energy to a stack and confidence when worn alone, with a graphic outline that feels deliberate from the first angle to the last.
The geometry is drawn with forty-seven prong-set stones rather than one dominant centre. Seven precise sizes, from 0.80mm to 1.40mm, allow the lab-grown diamonds to fit the changing angles of the gold. Twenty-eight measure 1.20mm, forming the rhythm at the core of a design built around direction, repetition and an unexpected line.
Also in sterling silver. Allegra is available in 925 sterling silver — see the silver version.
Allegra gives a ring stack a new direction, using shape rather than height to hold attention. Its forty-seven round lab-grown diamonds total 0.34ct and follow every angle of the zigzag, with seven sizes fitting the changing geometry. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. White, Yellow or Rose Gold lets the graphic outline feel crisp, warm or softly contrasted.

Every piece is crafted to your chosen metal and size. Our usual timeline is around four weeks from order to dispatch, which includes UK hallmarking where required. More complex pieces may take slightly longer. We confirm the expected timeframe in writing before production begins.
Allegra can break up a row of straight bands, adding an angular line to a considered stack. Worn alone, the full zigzag reads clearly across the finger. Pair it with simpler jewellery elsewhere, or repeat your chosen gold colour so the unusual geometry remains the detail that draws the eye.
Why does Allegra use seven stone sizes?
The forty-seven round lab-grown diamonds range from 0.80mm to 1.40mm. Those seven sizes allow the stones to follow the changing angles of the zigzag, maintaining the graphic line as the gold changes direction across the finger.
How much total lab-grown diamond weight is in Allegra?
Allegra has approximately 0.34ct total lab-grown diamond weight across forty-seven round stones. Twenty-eight of them measure 1.20mm, creating a consistent rhythm through the centre of the angular prong-set arrangement.
How do I order the right size for Allegra?
