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.
Not every ring needs to be gentle. Allegra is modern and a little daring, a zigzag of 925 sterling silver that crosses the finger with clean corners in place of soft curves. Every angle is set with lab-grown diamonds, so the sharp outline is drawn in stones.
Forty-seven round lab-grown diamonds make up the zigzag, all in prong settings, with a total weight of 0.34ct. They come in seven sizes, from 0.80mm to 1.40mm, and 28 of them measure 1.20mm. The cool silver keeps the focus on the shape.
Prefer gold? Allegra is also made in solid 14kt and 18kt gold — see the gold version.
Allegra is a zigzag in 925 sterling silver with 47 prong-set round lab-grown diamonds following every angle. Together they total 0.34ct, in seven sizes from 0.80mm to 1.40mm. It is a ring with a bit of attitude, and the zigzag does the talking. Each stone is D to F colour and VS1 clarity or better.
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. Standard UK sizes are available — if you need guidance, contact us before placing your order.
Every piece is crafted to your chosen metal and size. Our usual timeline is around four weeks from order to dispatch. More complex pieces may take slightly longer. We confirm the expected timeframe in writing before production begins.
Wear Allegra when you want a ring with a bit of attitude. It sits happily on its own, or in a stack with plain silver bands. Simple silver earrings or a fine bracelet leave the zigzag as the one bold detail.
Sterling silver naturally darkens a little over time. It is normal, and a silver polishing cloth brings it straight back. Please don't use silver dip solutions on lab-grown diamond-set pieces, as the chemicals can damage the settings. Store it on its own in the pouch or box provided, and take it off before swimming, exercising or sleeping. See our Materials & Care guide for full instructions.
What makes Allegra look so graphic?
The silver band changes direction in sharp angles, and every angle is set with a round lab-grown diamond in a prong setting. The result is a crisp, angular outline in place of a soft curve.
Which is the smallest stone in Allegra?
The smallest round lab-grown diamonds measure 0.80mm, and there are three of them. The largest single stone measures 1.40mm, while 28 of the 47 stones measure 1.20mm.
Does Allegra work in a ring stack?
Yes. Allegra is a ring that stands out in a stack. Beside a plain silver band, the zigzag stays distinct and adds a sharper outline to the pair.
