Lab-Grown Diamond Engagement Ring

The elongated silhouette of the 5 x 3 mm marquise diamond draws the eye along the finger, offering a subtle yet striking statement. This semi-set engagement ring foundation in 14K white gold features delicate accent settings designed for a secure, low-profile fit that slides comfortably beneath gloves and daily wear.

Crafted with precision in Williamsburg, Brooklyn, the band’s smooth finish and balanced weight ensure it feels as natural as it looks. The mounting’s refined prong structure protects the stone while allowing light to animate the marquise’s signature pointed ends.

Each piece embraces lab-grown clarity, reflecting a commitment to sustainable luxury without compromise. The ring’s streamlined design suits those seeking an elegant shape that complements slender or average finger proportions, ideal for stacking or solo wear.

Resizing is straightforward, handled in-studio with care to maintain the integrity of the setting and comfort fit. Whether you choose to complete the ring with a custom marquise center or explore other shapes, this semi-set offers a versatile foundation.
