Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along a graceful arc—both bold and refined. This semi-set halo mounting in platinum frames a 10 x 5 mm marquise center with a delicate ring of pavé diamonds, enhancing brilliance while maintaining a low profile suited for everyday wear.

Crafted in Williamsburg, the platinum band is polished to a satiny finish that resists scratches and fits comfortably against the skin. The halo setting balances sparkle with subtlety, designed to sit close to the finger without catching on gloves or sleeves. Each prong is meticulously aligned to secure the pointed ends of the marquise, a shape known for its dramatic taper and elongating effect on the hand.

Our commitment to sustainability is reflected in the use of a lab-grown diamond, offering clarity and fire with a smaller environmental footprint. This ring’s streamlined silhouette suits those seeking a blend of architectural elegance and practical wearability.

Because this is a semi-set, you can select a marquise diamond that matches your personal preferences, ensuring the perfect balance of size and color. Resizing is available to accommodate your unique fit without compromising the integrity of the setting.
