1 Carat Marquise Cut 18k White Gold Lab Diamond Ring+ 1.0-Carat Marquise Lab Created Diamond

Yes. Lab diamonds are graded using the same 4Cs system as mined diamonds: cut, color, clarity, and carat weight. Certifications from labs like IGI, GIA, and GCAL are available. Reputable retailers provide certification documentation with every lab diamond so you know exactly what you are getting.

When freshly rhodium-plated, the two are nearly indistinguishable visually. As the plating wears, 18k may develop a slightly warmer yellow undertone compared to 14k because of its higher gold content. Both need periodic replating to maintain their bright white appearance, which effectively resets the color difference between them. Do Amore offers free maintenance services on white gold.

A 1 carat marquise stretches to approximately 10 x 5mm, creating a dramatic, elongated silhouette that stands out in an 18k white gold setting. The rich 75% gold composition provides a luxurious feel, while the white surface keeps the focus on the diamond's brilliant facets. The marquise shape naturally makes the finger appear longer and more slender, which many wearers love.

Yes, marquise cuts are prone to the bow-tie effect, a dark shadow across the center of the stone where light is not returned efficiently. A faint bow-tie is common and acceptable. A strong, dark bow-tie is undesirable. Cut quality and proportions determine how pronounced the bow-tie is, making it important to evaluate the specific stone rather than just relying on specs.

The premium 75% gold composition gives the setting a richer foundation, while the marquise shape's dramatic pointed ends and brilliant-cut facet pattern catch light from every angle.
