1 Carat Marquise Cut Yellow Gold Lab Diamond Ring+ 1.0-Carat Marquise 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.

14k yellow gold has a slightly paler color than 18k because it contains less gold. It is also harder and more scratch-resistant than 18k. For daily wear, 14k is the more practical choice. 18k has a richer, more deeply golden tone and a higher gold purity, which appeals to those who prioritize color over durability.

A marquise cut at 1 carat measures roughly 10 x 5mm, giving it the largest face-up area of any diamond shape. That elongated, boat-like silhouette makes the stone look significantly larger than its weight suggests. Set in 14k yellow gold, the warm metal contrasts beautifully with the lab diamond's white brilliance.

Significantly. The marquise's long, narrow silhouette is one of the most elongating shapes available. Worn with the points along the length of the finger, it creates a dramatic visual extension that makes fingers appear longer and more slender. This is one of the primary reasons the shape remains popular for engagement rings. A 1 carat stone hits the sweet spot that has defined engagement rings for decades: substantial enough to catch the eye, refined enough to suit any style.

The combination of a 1ct marquise lab diamond with 14k yellow gold is a favorite at Do Amore for its warm, regal aesthetic. The marquise shape, named after the Marquise de Pompadour, elongates the finger beautifully while the classic golden tone adds vintage charm. Every stone is conflict-free and lab-grown, identical to mined diamonds in every measurable way. Do Amore has funded clean water for over 22,000 people across 14 countries since 2017.
