Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated silhouette of a marquise diamond, it casts a slender, dramatic sparkle that draws the eye along the finger’s natural line. This semi-set solitaire ring foundation in 10K yellow gold awaits your choice of a 7 x 3.5 mm marquise center, designed to showcase the stone’s tapered elegance with a secure, low-profile setting.

Crafted in Williamsburg, the band balances durability with comfort—its smooth interior contours ensure a gentle fit for everyday wear, while the subtle prong structure keeps the diamond close to the hand, minimizing snagging. The warm glow of yellow gold complements the marquise’s fiery brilliance, finished with meticulous hand polishing and quality inspection.

Each diamond is lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising clarity or fire. This ring suits those who appreciate refined geometry and a sleek silhouette, ideal for stacking or wearing solo with ease.
