Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a delicate shimmer that seems to stretch beyond the finger. This semi-set halo ring foundation in warm 14K rose gold invites your choice of a 6 x 3.5 mm marquise center, its shape lending a graceful elongation to the hand with a hint of vintage drama.

Handcrafted in our Williamsburg studio, the band is carefully shaped for comfort with a low-profile halo setting that balances sparkle and wearability. The rose gold’s subtle blush complements the diamond’s fire, while the artisan finish ensures each curve and prong is smooth to the touch and polished to a soft glow.

Our lab-grown diamonds offer a clear, sustainable alternative—grown with precision and inspected for brilliance without compromise.

Designed for everyday elegance, this mounting suits those who appreciate a refined silhouette that layers beautifully with wedding bands or stackable rings. Its modest height and secure setting make it glove-friendly and ideal for active hands.

Should you need resizing, our Brooklyn studio provides expert adjustments to ensure a perfect fit without disrupting the ring’s balance.
