Elongated Cushion Cut Lab-Grown Diamond Engagement Rings

About Elongated Cushion Cut Lab-Grown Diamond Engagement Rings

An elongated cushion is a cushion cut with a length to width ratio of about 1.2 or more. It keeps the soft, rounded corners of a classic cushion and adds a longer outline that makes the diamond look larger on the finger. Every elongated cushion design here is sold as a complete ring, with a lab-grown center diamond of at least 1ct.

The price of a complete ring includes the center diamond and the setting. Each ring page shows the exact price for every size and metal, in 14k or 18k white or yellow gold, or platinum. Every ring is made to order and arrives in about 30 days.

The photos on these pages show a classic cushion center stone, so your elongated cushion will have a longer outline than the one pictured.

Compare the shape with cushion cut rings for a squarer outline, or with oval rings for a longer, fully rounded one.
