Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc of brilliance, evoking quiet drama and refined elegance. This semi-set engagement ring invites you to choose a center stone that measures 14 by 7 millimeters, its tapered points framed by a halo of meticulously placed pavé diamonds that amplify every flicker of fire.

Crafted in warm 18K rose gold, the band is polished to a soft glow, its gentle curve designed for comfort and daily wear. The halo setting sits low enough to slip easily beneath gloves or stack alongside complementary bands, while the secure prong work ensures the stone’s poised presence without excess height.

Each piece is hand-finished in our Williamsburg studio, where expert jewelers inspect every facet and setting under magnification to guarantee precision and durability. The rose gold’s subtle blush complements the marquise’s vintage-inspired shape, marrying modern craftsmanship with timeless romance.

Our commitment to sustainability is reflected in the use of lab-grown diamonds, offering exceptional clarity and brilliance with a lighter environmental footprint.

This ring suits those who appreciate a statement that is both bold and graceful—elongating the finger with its architectural form while remaining understated enough for everyday elegance.
