Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that feels like a whispered promise. This semi-set solitaire invites you to choose a 9 x 4.5 mm marquise center stone, its tapered points drawing the eye along a graceful arc.

Crafted in warm 18K rose gold, the mounting is shaped with a delicate balance—slender prongs cradle the stone while maintaining a low profile that rests comfortably against the finger. The band’s subtle curve and polished finish reflect the soft glow of the metal, designed for everyday wear without sacrificing elegance.

Each piece is hand-finished in our Williamsburg studio, where precision meets quiet artistry. The rose gold is carefully inspected to ensure a smooth, comfortable fit that complements the diamond’s distinctive shape.

Choosing a lab-grown diamond for this ring aligns with a commitment to ethical jewelry—offering clarity and brilliance with a smaller environmental footprint.

This solitaire suits those who appreciate refined romance and a silhouette that elongates the hand, ideal for stacking or wearing solo. Its low-profile setting slips easily beneath gloves or sleeves, making it a seamless companion for daily life.

Should you wish to adjust the band size, resizing is available to ensure a perfect fit without compromising the ring’s integrity.
