Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow that hints at quiet confidence. This semi-set engagement ring invites you to choose a 10 x 5 mm marquise center stone, its pointed ends drawing the eye along the finger with a subtle, sculptural elegance.

Crafted from warm 14K rose gold, the band supports a delicate five-stone arrangement, each accent diamond carefully bezel-set to enhance light play while maintaining a smooth profile. The low-set design ensures comfort for daily wear, slipping easily beneath gloves or alongside other stackable bands without catching.

Each ring is finished by hand in our Williamsburg studio, where precision meets a soft polish that catches the eye without glare. The rose gold’s gentle blush complements the marquise’s vintage-inspired shape, marrying modern craftsmanship with a romantic silhouette.

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

This ring suits those who appreciate refined details and a slender, elongating shape that flatters a variety of hand sizes. Its comfort fit and modest height make it an ideal choice for everyday elegance.

Should you wish to adjust the band size, resizing is available with care to preserve the ring’s delicate balance and finish.
