Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a subtle, tapered sparkle that draws the eye along the finger. This 10 x 5 mm lab-grown stone is nestled securely in a 14K rose gold setting, its gentle blush complementing the diamond’s fiery brilliance.

Crafted with a low-profile design, the ring sits close to the hand, minimizing snagging and enhancing everyday comfort. The rose gold band is polished to a soft sheen, with precise prong work that balances protection and light exposure, ensuring the diamond’s facets catch every glimmer.

Ethically sourced, the lab-grown diamond offers clarity and fire without the environmental cost of traditional mining. This ring’s refined silhouette suits those who appreciate a sleek, modern shape that elongates the finger while remaining understated.

Its slim band and secure setting make it ideal for stacking alongside wedding bands or wearing solo with ease. The comfort fit ensures it moves naturally with your hand, perfect for daily wear in any setting.

Should you need resizing, our Brooklyn studio offers expert adjustments without compromising the ring’s integrity or finish.
