Elongated Cushion Moissanite Engagement Rings
Elongated cushion moissanite engagement rings pair softly rounded corners with a lengthened outline. The result is a gentle, structured silhouette with a different character from an oval or a straighter-sided radiant cut. Compare the centre stone's measurements and the setting's profile to choose how the ring sits on your hand. Explore these designs alongside our broader moissanite engagement ring collection.

Buying guide
Choosing an elongated cushion moissanite ring
An elongated cushion combines length along the finger with softly rounded corners. It offers a useful middle ground for someone drawn to an oval's flow but also to the structure of a rectangular centre stone. The precise outline and setting determine whether the finished ring feels delicate, substantial or somewhere between.
Understand what elongated means
It describes the relationship between the length and width, not a separate gemstone or a quality grade. Compare the millimetre measurements and outline of each centre. A higher length-to-width ratio gives a more slender shape, but there is no single ratio that suits every hand or setting. Our cushion cut moissanite rings provide a useful reference for fuller proportions.
Compare curves with straighter lines
An oval moissanite ring has a continuous curved perimeter. A radiant cut moissanite ring has straighter sides and more defined cropped corners. Viewing these shapes together helps distinguish the silhouette you prefer from the size of the stone shown in a photograph.
Look beneath the centre stone
The longer outline can extend beyond the band. Check the basket, setting height and clearance for the wedding ring you expect to wear beside it. A fine band is a stylistic choice, not a guarantee of a low setting. Review the actual dimensions of designs in the wider petite moissanite collection.
How should I compare stone sizes?
Use length and width first. Diamond-equivalent weight, where quoted, is a comparison rather than the moissanite's actual weight. Assess the complete ring in relation to your hand, and use our consultation service to discuss proportion, metal and band pairing.
