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.
A hoop usually follows a curve. Helia sharpens it. Twenty-four marquise-cut lab-grown diamonds place their pointed oval profiles around the pair, creating a flowing edge that changes character as the earrings turn.
Each earring carries twelve 4.00 × 2.00mm stones, set closely along the front of a hoop measuring approximately 20.6mm across. The repeated marquise shape gives the design a long, soft line, while the hinged closure keeps the form complete. Across the pair, the 1.60ct composition is generous without losing the clear rhythm of each individual cut.
Helia turns the familiar hoop into a continuous procession of marquise cuts, giving every movement a sequence of pointed, elongated shapes. Twelve lab-grown diamonds on each earring bring the pair to approximately 1.60ct, so the design has substance from the front and through the curve. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. A secure hinged closure finishes each hoop.
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.
Let Helia carry the look alone with hair tucked behind the ears, or repeat its elongated shape with a marquise or pear pendant. The approximately 20.6mm hoops work with a clean shirt collar by day and remain clear against an open neckline in the evening.
Is the 1.60ct weight for one Helia hoop or the pair?
The approximately 1.60ct total is for the pair. Each earring is set with twelve marquise-cut lab-grown diamonds, giving you 24 stones across both hoops.
How large are the marquise-cut lab-grown diamonds?
Each of Helia's 24 marquise-cut lab-grown diamonds measures 4.00 × 2.00mm. The repeated pointed oval shape follows the curve of each hoop, which measures approximately 20.6mm across.
How do the Helia earrings close?
Each Helia hoop has a secure hinged closure. The earrings are made to order in your choice of 14kt or 18kt White, Yellow or Rose Gold and include a 12-month guarantee.
