Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that seems to stretch beyond the hand. This semi-set engagement ring invites you to select a 9 x 4.5 mm marquise stone, whose pointed ends and graceful curves evoke a quiet drama and refined elegance.

Crafted from warm 14K yellow gold, the mounting balances delicate strength with a low-profile design that rests comfortably for everyday wear. The solitaire setting is thoughtfully engineered to showcase the diamond’s unique shape while maintaining a secure, classic prong hold. Each ring is hand-finished in our Williamsburg studio, where meticulous inspection ensures a smooth band and flawless polish.

Choosing a lab-grown diamond here means embracing clarity and brilliance with a lighter environmental footprint, reflecting a modern approach to ethical jewelry.

Its slender band and modest height make this ring ideal for those who appreciate subtle sophistication—equally suited to stacking or wearing solo. The gentle curve of the marquise shape elongates the finger, offering a graceful silhouette that complements a variety of hand sizes.
