Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise shape, casting a subtle, elegant shadow that stretches across the hand. This semi-set solitaire ring features a 6 x 3.5 mm marquise center, designed to highlight the stone’s tapered drama without overwhelming daily wear.

Crafted in 14K yellow gold, the mounting offers a low-profile setting that sits close to the finger, ensuring comfort and ease beneath gloves or alongside stackable bands. The polished finish and secure prongs are meticulously inspected in our Williamsburg studio, balancing durability with refined minimalism.

Each diamond is lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

The slender silhouette suits those who appreciate a sleek, architectural form that elongates the finger, ideal for hands seeking a distinctive yet understated statement. Its comfort fit and modest height make it a practical choice for everyday wear.
