Frequently Asked Questions

Your questions, answered.

The marquise cut is named after the Marquise de Pompadour, said to have inspired the shape's design in 18th-century France. Its elongated, pointed silhouette was reportedly created to resemble the curve of her smile.

Yes. Sapphires rate 9 on the Mohs scale, making them one of the most durable gemstones after diamond. The pointed ends benefit from a protective setting such as a V-claw or bezel to guard against everyday impact. Keep reading about durability in The complete low-down on Sapphire Engagement Rings.

A curved or contoured wedding band follows the marquise's pointed ends for a seamless fit. A slim straight band also works well, sitting flush against the widest part of the stone without interference.

All Cullen sapphires are lab-grown, sharing the same crystal structure, hardness, and brilliance as mined sapphires. They are conflict-free, carbon-neutral, and offer a more accessible alternative to traditional mined center stones. For more information on sapphires, read our blog What are Lab Grown Sapphires?

Clean your marquise sapphire ring regularly with warm water, a mild dish soap, and a soft-bristled brush, paying attention to the pointed ends where debris can collect. Dry with a lint-free cloth. For full guidance, visit our Ring Care Guidance page.

Yes. All Cullen marquise cut sapphire engagement rings can be personalized across carat weight, metal, setting style, and band width. For a fully tailored design, our custom design service allows you to design from the ground up.

Marquise Cut Engagement Rings For A Bold And Confident Love

Marquise cut sapphire engagement rings carry an instantly recognizable silhouette, far less common than round or oval cuts. Pointed ends and a curved center create a shape that feels both regal and contemporary, while the elongated form makes the finger appear longer and slimmer, a flattering effect for engagement ring designs. The marquise cut also has a large surface area relative to its carat weight, so the sapphire often looks larger than other cuts of the same size, delivering impact without extra weight. Its versatile silhouette suits everything from minimalist solitaires and vintage-inspired designs to east-west settings and halos.

Superior craftsmanship, thoughtful customization, and premium materials are the foundation of every Cullen ring. The rest is shaped by you. Our jewelers and ring specialists are here to guide you through every step of finding the one. Each piece is brought to life using premium precious metals and carbon-neutral stones, including lab-grown diamonds, moissanite and lab-grown sapphires, crafted with exceptional care and attention to detail.
