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 path needs to meet in the middle. Iona lets its fine silver band pass by itself, creating a bypass shape that feels open, modern and easy to make your own. The stones grow towards the front, so the ring has a sense of arrival without needing a raised centre or a large motif.
Seven round lab-grown diamonds travel along the sweep in four exact sizes: 1.00mm, 1.20mm, 1.30mm and 1.40mm. They are held in micro prong settings and total approximately 0.06ct. Made in 925 sterling silver, Iona uses the changing scale to guide the eye through its open form and towards the front of the finger.
Prefer gold? Iona is also made in solid 14kt and 18kt gold — see the gold version.
Iona is a light everyday choice with enough movement to feel distinctive. Seven round lab-grown diamonds increase in size along the bypass sweep, and every stone is D to F colour and VS1 clarity or better. The ring is made in 925 sterling silver, with micro prong settings supporting its fine design. Select your UK ring size and it will be made for you at no extra charge.
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 Iona alone to let the open bypass line show, or place it beside a narrow plain silver band for contrast. Its fine profile also works with understated silver earrings and bracelets. Keep neighbouring rings simple so the growing stones remain the detail your eye follows.
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.
How much lab-grown diamond weight is in Iona?
Iona has seven round lab-grown diamonds with a combined weight of approximately 0.06ct, set along the sweep of the bypass in four different sizes.
Which sizes appear along Iona's sweep?
The design uses one 1.00mm, two 1.20mm, two 1.30mm and two 1.40mm round lab-grown diamonds. Their changing sizes draw the eye towards the front of the bypass ring.
What does micro prong setting mean for Iona?
Each of Iona's seven round lab-grown diamonds is held in a micro prong setting, a very fine style of prong that suits the fine silver band and lets the four stone sizes read clearly.
