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 engagement ring, set in cool 14K white gold, frames an 8 by 4 mm marquise center with two gently tapering side stones, creating a quiet balance between bold geometry and refined grace.

Each diamond is carefully bezel-set to sit low against the hand, offering a sleek profile that slips easily beneath gloves or daily wear. The band’s subtle comfort fit and polished finish reflect the meticulous craftsmanship honed in our Williamsburg studio, where every curve and angle is shaped and inspected by hand.

Our commitment to ethical jewelry is embodied in the lab-grown diamonds, which deliver exceptional clarity and brilliance with a smaller environmental footprint.

This ring suits those who appreciate architectural elegance paired with understated romance—its elongated shape visually lengthens the finger, while the three-stone design symbolizes a shared past, present, and future. Its low profile and smooth edges make it ideal for stacking or wearing solo with ease.

Should you need resizing, our Brooklyn studio offers thoughtful adjustments to ensure a perfect fit without compromising the ring’s integrity.
