Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a slender finger, crowned by a marquise diamond’s tapered silhouette catching light with every movement. This semi-set engagement ring foundation in warm 10K yellow gold awaits a 6 x 3 mm marquise center, designed to sit low and close to the hand for everyday grace.

Crafted with precision, the band’s gentle curve and secure prongs ensure comfort and durability without excess height. Its low-profile setting minimizes snagging, making it an ideal choice for those who value both elegance and practicality. The warm glow of yellow gold complements the marquise’s dramatic shape, enhancing its vintage-inspired allure.

Each piece reflects our commitment to sustainability, featuring a lab-grown diamond center that offers clarity and brilliance with a lighter environmental footprint. This ring suits wearers who appreciate refined details and a design that integrates seamlessly with daily life, whether worn solo or stacked alongside other bands.

Should you need adjustments, resizing is handled expertly in-studio to maintain the ring’s balanced proportions. Lead times are typically brief, allowing you to move from design to delivery with ease.
