An elongated cushion alexandrite gives this 18k yellow gold Paris ring its centre of colour. The hidden halo is positioned beneath the gemstone, offering a side view detail while the solitaire outline stays open from above.

The lab-grown alexandrite is presented in an elongated cushion cut. Its softened corners and longer face keep the single centre distinct from the smaller diamond accents. The hidden halo sits beneath it, providing a separate detail in profile.

Yellow gold supplies a warm metal outline beneath the gemstone. The 1.65mm band keeps the silhouette fine, with the hidden halo positioned below the centre. Diamond accents are graded G/H SI separately from the coloured gemstone.

From above, the softened rectangular gemstone remains the main silhouette. Turned to the side, the hidden halo adds detail below it; the accent diamonds and coloured centre keep their separate roles.

Available elongated cushion options run from 1.12ct / 7x5mm to 4.11ct / 10x8mm across four selections. Each variant lists a carat figure and millimetre dimensions for the centre gemstone. Compare the proportions as well as the weight when choosing the Paris setting.

Paris Elongated Cushion Lab-Grown Alexandrite Hidden Halo Engagement Ring

Paris gives the elegant hidden-halo setting a different character with an elongated cushion-cut lab-grown alexandrite centre. The gemstone's softened rectangular outline takes centre stage in 18ct yellow gold, while a discreet diamond halo sits beneath the setting rather than surrounding the stone from above. The result is a refined engagement ring with colour at its heart.

Petite 1.65mm Yellow Gold Band and Diamond Hidden Halo

The fine 1.65mm band keeps the centre alexandrite prominent. G/H SI diamond accents add a separate detail beneath the gemstone, becoming more visible as the ring turns to the side. This is a useful distinction when comparing Paris with a conventional halo: the upper view stays uncluttered while the profile reveals the additional diamond setting.

Choosing the Size and Appearance of Your Alexandrite

The elongated cushion alexandrite is offered in sizes from approximately 7 × 5mm to 10 × 8mm. Compare its millimetre dimensions and appearance in different lighting conditions as well as carat weight. The coloured centre is a lab-grown alexandrite, not a lab-grown diamond; the halo diamonds are separate accent stones.
