Lab-Grown Diamond Engagement Ring

Light catches the marquise diamond’s tapered points, casting a delicate sparkle that seems to dance with every movement. This halo setting cradles the 7 x 3.5 mm lab-grown stone in a platinum embrace, where the cool metal’s subtle sheen enhances the diamond’s elongated silhouette.

Handcrafted in Williamsburg, the ring’s low-profile halo setting balances brilliance with everyday wearability, while the comfort-fit band ensures it rests gently against the finger. Each facet is meticulously polished and inspected to reveal the marquise’s signature blend of drama and refinement.

Created with a commitment to sustainability, the lab-grown diamond offers clarity and fire without the environmental cost of traditional mining. The slender shape naturally elongates the hand, making it an elegant choice for those who appreciate a refined yet distinctive statement.

Its streamlined design pairs effortlessly with stacking bands or stands alone as a singular expression of intention. Resizing is available to ensure a perfect fit, crafted with the same care as the original design.
