Lab-Grown Diamond Engagement Ring

When light catches the elongated marquise shape, it draws the eye along a graceful silhouette that feels both bold and refined. This semi-set halo engagement ring foundation in 14K white gold offers a delicate frame designed to cradle a 9 x 4.5 mm center stone, emphasizing the marquise’s tapered drama without overwhelming the finger.

Crafted with a low-profile setting, the band sits close to the hand, ensuring comfort for daily wear and ease beneath gloves or rings stacked alongside. The halo setting’s precision milgrain edges and secure prongs are finished by hand in our Williamsburg studio, where each piece undergoes meticulous inspection to balance sparkle with durability.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, which provide exceptional clarity and brilliance with a smaller environmental footprint.

This ring mounting suits those who appreciate architectural elegance paired with practical design—ideal for slender fingers or anyone seeking a statement that remains understated in everyday life.

Should you wish to adjust sizing or explore stone options, our Brooklyn studio offers personalized consultations to ensure a seamless fit and finish.
