Cushion Engagement Rings by Setting Style

Cushion Solitaire Engagement Rings

A solitaire engagement ring keeps the cushion centre diamond as the main focus, highlighting its soft corners and balanced shape.

Cushion Hidden Halo Engagement Rings

Hidden halo engagement rings add subtle sparkle beneath the cushion centre stone while maintaining a clean appearance from above.

Cushion Pavé Engagement Rings

Pavé engagement rings pair a cushion centre diamond with small diamonds along the band for extra brilliance and a more detailed finish.

Cushion Cathedral Engagement Rings

Cathedral engagement rings use raised shoulders to frame the cushion centre stone and create a graceful, structured profile.

Why Choose a Cushion Diamond?

Cushion diamonds are known for their soft corners, romantic proportions and brilliant faceting. They offer a balance between the classic appeal of a round shape and the stronger outline of a square or rectangular diamond.

Cushion diamonds are also highly versatile and work well with solitaire, hidden halo, pavé, cathedral, trilogy and bezel settings.

Cushion Engagement Rings by Metal

Yellow gold gives a cushion diamond a warm and classic look, while white gold and platinum create a bright, refined appearance. Rose gold provides a softer and more distinctive finish.

Depending on the design, Nura Lab rings may be available in 9K, 14K or 18K gold as well as platinum.

Cushion Lab Grown Diamond Engagement Rings

Lab grown cushion diamonds have the same crystal structure and fundamental physical properties as mined diamonds, with the main difference being their origin.

They are available in a wide range of carat weights, colours and clarity grades, giving you flexibility when choosing the size, quality and proportions that suit your preferences.

Many Nura Lab centre diamonds are available with independent grading reports, including IGI certification.

Square vs Elongated Cushion Diamonds

Cushion diamonds can range from near-square proportions to more elongated rectangular shapes.

A square cushion creates a balanced, compact appearance, while an elongated cushion offers greater length across the finger and a more contemporary look.

When creating a custom cushion engagement ring, Nura Lab can help you compare different proportions before selecting your centre diamond.

Cushion Engagement Rings FAQs

What is a cushion cut diamond?

A cushion cut diamond has a square or rectangular outline with rounded corners and brilliant-style faceting.

Are cushion diamonds good for engagement rings?

Yes. Cushion diamonds are popular because they combine a soft, romantic outline with strong brilliance and work well with many setting styles.

What is the difference between a square and elongated cushion?

A square cushion has more balanced length and width proportions, while an elongated cushion has greater length and a more rectangular appearance.

Do elongated cushion diamonds look larger?

Elongated cushions can create greater visual length across the finger, although the overall appearance depends on the individual diamond's dimensions and proportions.

What setting works best for a cushion diamond?

Cushion diamonds work well with solitaire, hidden halo, pavé, cathedral, trilogy and bezel settings.

Can a cushion engagement ring be made low profile?

Yes. Depending on the centre diamond dimensions and basket design, a cushion engagement ring can often be set relatively low while maintaining appropriate support and security.

Can I customise a cushion engagement ring?

Yes. Diamond proportions, carat weight, metal, band width, prongs, hidden halo, pavé detailing and setting height can all be considered during the custom design process.

How long does a custom cushion engagement ring take?

Most custom and made-to-order Nura Lab engagement rings take approximately 4–6 weeks after the final design and CAD have been approved, although timing can vary depending on the design and diamond availability.
