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.
Rosamund balances brilliance with calm. An elongated radiant centre takes the lead, while two emerald-cut side stones bring measured, step-cut lines beside it. The result is a trilogy that feels expressive at the centre and composed at the edges, with each shape strengthening the next.
The 7.50 × 5.50mm radiant-cut lab-grown diamond weighs approximately 1.5ct. A 3.50 × 2.50mm emerald-cut lab-grown diamond sits on either side, following the centre's proportions. All three rest low across a smooth, gently tapered band, meeting it flush so the line remains clean and uninterrupted around the finger.
Rosamund brings the meaning of a trilogy together through a balanced pairing of cuts. The radiant centre provides the greatest presence, while two emerald-cut sides extend its rectangular line without crowding it. Together they weigh approximately 1.70ct, and the centre includes an independent IGI grading report. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel.

Rosamund sits low and balanced, making its three stones feel united rather than separate. Wear it alone for an engagement or anniversary so the contrast between radiant and emerald cuts remains clear, with the smooth tapered band providing a quiet finish.
How large is Rosamund's radiant centre?
The radiant-cut lab-grown diamond measures 7.50 × 5.50mm and weighs approximately 1.5ct. Its elongated proportions are echoed by the two emerald-cut side stones, giving the trilogy a balanced line.
What are the sizes of the side stones?
Each emerald-cut lab-grown diamond measures 3.50 × 2.50mm. They sit flush with the gently tapered band on either side of the radiant centre, helping the ring maintain its clean, uninterrupted profile.
Does Rosamund come with an IGI grading report?
Yes. Rosamund includes an independent IGI grading report for its centre lab-grown diamond at no extra cost. Every lab-grown diamond used is D to F colour and VS1 clarity or better.
