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.
Three emerald cuts hold the gaze, then a line of round stones carries it onwards. Dorothea turns the meaning of a trilogy into a strong piece of geometry, with the broad centre flanked by two matching shapes and light continuing along the shoulders.
The 2.00ct emerald-cut centre lab-grown diamond measures 8.70 x 6.30mm. Beside it sit two 5.00 x 3.00mm emerald-cut lab-grown diamonds at 0.26ct each, while twelve 1.40mm round lab-grown diamonds run along the shoulders. Together, the 15 stones total 2.66ct, balancing clean lines, softer points of light and a clear three-part centre.
Dorothea builds its trilogy from three emerald-cut lab-grown diamonds, with twelve round lab-grown diamonds along the shoulders. Its 2.00ct centre sits within 2.66ct across the complete design, and an independent IGI grading report documents that centre stone. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel.
This ring is made to order in your size. Choose your UK ring size when you order — there is no extra charge for any size. If you are unsure of your size, our ring sizer makes it easy at home — and your £5 comes straight back to you as a gift card.

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.
Dorothea carries light across the front of the hand, so it works beautifully as an engagement ring and has enough presence for anniversaries or evening wear. Pair it with a plain band that lets the emerald-cut trilogy stay clear, and choose White, Yellow or Rose Gold to suit the jewellery you already wear.
