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.
Constance speaks in clean lines. The emerald-cut centre stretches the eye lengthways, while two princess-cut sides bring square geometry to its edges. Nothing needs softening or disguising. The attraction is in the order, proportion and calm confidence of three structured stones.
A 6.00 × 4.00mm emerald-cut lab-grown diamond sits between two 3.75 × 3.75mm princess lab-grown diamonds. The centre weighs 0.50ct and the side pair 0.66ct together, giving 1.16ct across the trilogy. Step-cut clarity meets the compact symmetry of princess shapes, and that contrast gives Constance its character.
Also in sterling silver. Constance is available in 925 sterling silver — see the silver version.
Constance offers over a carat through three stones with a strong architectural relationship. The long emerald cut and square princess cuts create a balanced trilogy for someone drawn to precision rather than ornament. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. Select White, Yellow or Rose Gold, or discover the separate 925 sterling silver version.
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.

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.
The straight edges of Constance give it a neat, composed presence that works particularly well on its own. Pair it with a plain band to keep the three silhouettes easy to read. White Gold reinforces the cool geometry, while Yellow or Rose Gold makes each outline more distinct.
What size is Constance's centre stone?
The emerald-cut centre lab-grown diamond measures 6.00 × 4.00mm and weighs 0.50ct. It is framed by two 3.75 × 3.75mm princess lab-grown diamonds.
How much lab-grown diamond weight does Constance have?
The three lab-grown diamonds total approximately 1.16ct. The princess side stones account for 0.66ct together, balancing the 0.50ct emerald-cut centre.
Can I order Constance in Rose Gold?
Yes. Constance is available in 14kt or 18kt Rose Gold, as well as White and Yellow Gold. It is made to order in your chosen UK ring size at no extra charge.
