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.
No two glances around Callisto meet quite the same shape. Its open circle gathers pointed, curved and straight-edged cuts into one complete thought, made for someone who likes order with a little surprise inside it. The result feels expressive without becoming crowded.
Sixteen lab-grown diamonds sit side by side around the ring in collet settings: 4 round, 5 marquise, 4 pear and 3 emerald-cut. Their different outlines interrupt the light in different ways, while the open centre gives the arrangement room to breathe. At approximately 23.1 x 23.2mm, the circle has presence while retaining a clean, balanced form.
Callisto offers the character of four cuts in a single 1.70ct composition, so there is always another detail to find. Its 16 lab-grown diamonds turn a familiar circle into something personal and less predictable. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. White, Yellow and Rose Gold are available in both purities.
Supplied on a fine cable chain. Choose 16, 18 or 20 inches above — 18 inches is our standard and the price is the same whichever you pick.
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.
Let Callisto sit just below the collarbone with an open shirt, square neckline or simple dress. Its near-circular 23.1 x 23.2mm form works well on its own. If you layer it, choose a shorter plain chain so the mixed cuts keep their space.
What lab-grown diamond cuts are in Callisto?
Callisto contains 4 round lab-grown diamonds at 3.50mm, 5 marquise at 4.00 x 2.00mm, 4 pear at 4.40 x 3.00mm and 3 emerald-cut at 3.25 x 2.40mm.
How large is the Callisto pendant?
The open circle measures approximately 23.1 x 23.2mm and contains 16 lab-grown diamonds totalling approximately 1.70ct. The open centre keeps the four-cut arrangement visually clear.
Can I choose a different chain length?
Yes. Callisto comes on a fine cable chain at the standard length shown in the render. An alternative length can be arranged as part of your made-to-order enquiry.
Store separately in the pouch or box provided. Avoid contact with harsh chemicals, perfume, and chlorine. Clean gently with a soft cloth or mild soap solution. Remove before swimming, exercising, or sleeping. See our Materials & Care guide for full instructions.
