1 Carat Cushion Cut 18k Rose Gold Lab Diamond Ring+ 1.0-Carat Cushion Lab Created Diamond

Yes. The FTC updated its definition of diamond in 2018 to remove the word natural, recognizing that lab diamonds meet every scientific criterion to be called a diamond. They are not simulants, not imitations, and not glass. They are diamonds, grown in a lab rather than mined from the ground.

Softer. Higher gold content means less hardening alloy, making 18k rose gold more susceptible to surface scratches than 14k. For a ring worn every day, 14k rose gold is the more practical choice. That said, 18k's higher purity appeals to those who want premium gold content, and it can be polished to restore its surface. At this size, 1 carat delivers the look most people picture when they think of an engagement ring. It is the original benchmark for a reason.

A cushion cut's rounded, pillow-like shape radiates a soft, romantic energy that naturally aligns with rose gold's blush tone. At 18k, the rose gold has a subtler pink than 14k, letting the lab diamond remain the focal point. The combination is especially popular for those who want a vintage-inspired look with a modern, ethical stone.

Both. The cushion cut has roots in 19th-century cutting styles, which gives it a romantic, antique feel that suits vintage-inspired settings beautifully. But it has also been modernized with updated facet patterns that produce brilliant light performance. It is one of the few shapes that works equally well in a Georgian-inspired setting and a contemporary minimalist ring. For years, 1 carat was the aspirational standard. Lab-grown options have made this timeless size even more attainable.

18k rose gold offers a subtler pink than 14k because its higher gold content balances the copper, producing a refined rosy warmth that complements the cushion cut's soft sparkle at 1 carat. Do Amore handcrafts every ring in the US using recycled metals and conflict-free lab-grown stones. The brand appeared on Shark Tank as the only engagement ring company to pitch its ethical giving model on national television.
