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.
Tamsin takes one graceful curve and repeats it three times. The pear centre narrows to a fine point, while two smaller pear shapes turn towards it from either side. Their shared outline gives the ring a quiet symmetry, but the angled side stones keep the arrangement alive rather than rigid.
A 9.0 × 6.0mm pear-cut lab-grown diamond forms the centre and weighs approximately 1.20ct. Beside it sit two 5.0 × 3.0mm pear-cut lab-grown diamonds, each approximately 0.16ct. The trio rests on a smooth, gently tapered band with a polished finish, creating a balanced, architectural profile with approximately 1.53ct in total.
Tamsin makes the trilogy feel unified by using the same tapering shape for all three stones. The angled side stones follow the sweep of the centre, creating symmetry without flattening its distinctive pear outline. The three stones total approximately 1.53ct, 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.

Tamsin's polished tapered band keeps the three pear shapes firmly in focus. Wear it alone for an engagement or anniversary, or place it beside a slim plain band that supports the design without interrupting the sweep created by the angled side stones.
What size is Tamsin's centre lab-grown diamond?
The pear-cut centre measures 9.0 × 6.0mm and weighs approximately 1.20ct. Its tapering shape leads the design, with two smaller pear-cut side stones angled to follow the same line.
How large are Tamsin's side stones?
Each pear-cut lab-grown diamond side stone measures 5.0 × 3.0mm and weighs approximately 0.16ct. With the centre included, Tamsin contains three stones weighing approximately 1.53ct in total.
