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.

The heart is recognised before a word is spoken. Nihal draws that familiar shape as an open gold outline, then gives it a distinctive rhythm with round lab-grown diamonds in two sizes. Romantic, yes, but considered in every part.

Two 2.70mm lab-grown diamonds sit in bezel settings among eighteen 1.60mm stones in U-cut settings. The change of scale breaks the repetition and gives the twenty-stone heart its own identity, with approximately 0.48ct across a pendant measuring approximately 13.1 x 11.7mm. Because the centre remains open, the gold outline and the stones work together rather than filling the shape completely.

Also in sterling silver. Nihal is available in 925 sterling silver — see the silver version.

Nihal says it clearly

Nihal makes a meaningful gift because its heart is immediate, yet the two larger lab-grown diamonds keep it from feeling ordinary. Twenty stones total approximately 0.48ct, giving the compact open shape detail without closing its centre. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. It is also available as a separate design in 925 sterling silver.

Made to Order

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.

Wearing Nihal

Nihal's 13.1 x 11.7mm heart sits neatly at the neckline for everyday wear, then carries easily into evening. Pair it with an open neck or a simple top so the outline stays distinct. If layering, place a plain chain at another length and keep the heart as the only shaped centrepiece.

Questions about Nihal

Why are two stones in Nihal larger?
Two round lab-grown diamonds measure 2.70mm and sit in bezel settings, creating points of emphasis within the heart. The other eighteen round lab-grown diamonds measure 1.60mm and use U-cut settings to complete the open outline.

What size is the Nihal heart?
The heart pendant measures approximately 13.1 x 11.7mm. It contains twenty round lab-grown diamonds totalling approximately 0.48ct, arranged around an open centre that keeps the heart shape clear and light.

Which metal options are available for Nihal?
Nihal can be made in 14kt or 18kt White, Yellow or Rose Gold. A separate 925 sterling silver version is also available, and every lab-grown diamond is D to F colour and VS1 clarity or better.
