Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of a marquise diamond catching the soft morning light, its elongated silhouette tracing a delicate arc across your finger. This semi-set solitaire invites you to choose a 6 x 3.5 mm marquise center stone, known for its graceful taper and subtle drama that visually lengthens the hand.

Crafted in warm 10K rose gold, the band offers a tender glow that complements the diamond’s fiery facets. The low-profile setting ensures everyday comfort, while the smooth finish and precise prong work reflect careful handcrafting in our Williamsburg studio. Each piece undergoes meticulous inspection to meet exacting standards.

Our diamonds are lab-grown, offering a clear, sustainable choice that honors both beauty and ethics without compromise.

This ring suits those who appreciate refined romance and a subtle statement—its slender band and low profile make it ideal for stacking or wearing solo, with a fit designed for daily life and glove-friendly ease.

Should you wish to adjust sizing, our Brooklyn studio offers expert resizing to ensure a seamless fit.
