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.
Some earrings soften a square centre. Iskra gives it a stronger edge. The crisp geometry of a princess cut remains the focus, then a precise border of smaller rounds builds the shape outwards.
Each stud begins with a 4.30mm princess cut lab-grown diamond in a prong setting. Sixteen 1.25mm round lab-grown diamonds form the U-cut square halo around it, making 34 stones and approximately 1.28ct across the pair. At approximately 7.3mm across, the design combines two distinct cuts in one clearly defined square composition.
Iskra gives the clean corners of a princess centre more reach through a closely worked square halo. Across the pair, two 4.30mm centres and 32 smaller rounds bring the total to approximately 1.28ct, so the detail is present in both scale and contrast. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. Three gold colours complete the choice.
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.
The approximately 7.3mm square face gives Iskra a defined outline with a centred look on the ear. Wear the pair as your main earrings with a clean neckline, or combine them with a fine gold necklace that repeats your chosen White, Yellow or Rose Gold.
Which cuts are used in the Iskra earrings?
Each Iskra stud has one 4.30mm princess cut lab-grown diamond at its centre and sixteen 1.25mm round lab-grown diamonds around it. This brings the pair to 34 stones and approximately 1.28ct in total.
How large are the Iskra studs?
Each Iskra earring measures approximately 7.3mm across. The square shape comes from the princess cut centre and its surrounding square halo, so that stated size includes the complete face of the design.
How are the stones set in Iskra?
The two princess cut lab-grown diamonds are held in prong settings. The 32 round lab-grown diamonds use U-cut settings around the square halos, keeping the two stone shapes visually distinct within the same design.
