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.
Lumi turns careful geometry into something light. Its stones spread from the centre along fine spokes, creating a snowflake that feels open and finely drawn rather than solid against the ear.
Each earring uses a balanced arrangement of round lab-grown diamonds in three graduated sizes. Across the pair, six 1.80mm centre stones anchor the motifs, while twelve 1.60mm and twelve 1.50mm stones form the tapering outer points. Every stone sits in its own collet, and a smooth bar-style post top supports each approximately 15 × 13.6mm snowflake.
Also in sterling silver. Lumi is available in 925 sterling silver — see the silver version.
Lumi spreads 30 lab-grown diamonds across two airy, symmetrical motifs, giving the pair definition without filling every space with metal. Three graduated stone sizes shape the centres and tapering points, while individual collets keep the rounds clearly framed. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. Lumi is also available in a separate sterling silver version.
Every piece is crafted to order in your chosen metal. 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.
Lumi brings a precise, wintry detail to soft knitwear, dark evening fabrics or a simple open neckline. At approximately 15 × 13.6mm, each motif has enough width to read clearly while the open spokes prevent the design from appearing dense.
How many lab-grown diamonds form the snowflakes?
The pair contains 30 round lab-grown diamonds. Six measure 1.80mm, twelve measure 1.60mm and twelve measure 1.50mm, creating the graduated centres and radiating points.
How large is each Lumi earring?
Each snowflake measures approximately 15 × 13.6mm. Its open spokes spread the round lab-grown diamonds across that shape while leaving space between the radiating sections.
Can Lumi be made in sterling silver?
Yes. Lumi is also available in 925 sterling silver, on its own page.
