Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a delicate dance of light that seems to stretch beyond the finger. This three-stone semi-set ring in warm 14K rose gold frames an 8 x 4 mm marquise center, its pointed ends drawing the eye along a graceful line.

Each band is hand-finished in Williamsburg, with a low-profile setting that balances presence and everyday ease. The rose gold’s subtle blush complements the diamond’s crisp facets, while the three-stone arrangement offers a quiet narrative of past, present, and future. Comfort fit edges ensure the ring settles gently, inviting daily wear without interruption.

Crafted exclusively with lab-grown diamonds, this piece reflects a commitment to ethical jewelry that honors both beauty and sustainability.

Ideal for those who appreciate refined geometry and romantic symbolism, the marquise shape elongates the finger, pairing effortlessly with stacking bands or worn solo. Its slender profile slips easily beneath gloves or sleeves, making it a versatile choice for life’s varied moments.

Should you wish to adjust sizing, our Brooklyn studio offers expert resizing to maintain the ring’s integrity and comfort.
