Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate dance of light that seems to stretch beyond the finger. This three-stone semi-set engagement ring in 18K rose gold frames a 12 x 6 mm marquise center, its pointed ends drawing the eye along the hand’s natural line with quiet elegance.

Crafted in Williamsburg, the band’s gentle curve and polished finish offer a comfortable fit for daily wear, while the three-stone setting balances presence with subtlety. Each prong is meticulously shaped to cradle the stone securely, allowing the diamond’s facets to breathe and shimmer without interruption.

Our commitment to ethical jewelry shines through the use of a lab-grown diamond, chosen for its clarity and sustainable origin, reflecting a modern approach to love and responsibility.

The ring’s low-profile design suits those who appreciate refined romance and practicality—ideal for stacking with a wedding band or worn solo as a statement of enduring affection. Its size and shape complement slender to medium fingers, enhancing the hand’s natural grace.

Should you wish to adjust the fit, resizing is available through our Brooklyn studio with care that preserves the ring’s integrity.
