Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that elongates the finger with subtle elegance. This semi-set halo engagement ring in platinum offers a refined foundation, ready to cradle a 9 x 4.5 mm marquise center stone with a secure, low-profile setting designed for everyday grace.

Crafted in platinum, the mounting balances durability with a smooth comfort fit, its halo setting enhancing brilliance while maintaining a sleek profile that slips easily beneath gloves or sleeves. Each curve and prong is meticulously finished in our Williamsburg studio, ensuring a flawless surface and precise alignment for lasting wearability.

Choosing a lab-grown diamond for this ring aligns with a commitment to ethical jewelry, minimizing environmental impact without compromising on clarity or fire. The halo design amplifies the marquise’s distinctive shape, making it ideal for those who appreciate architectural drama paired with practical elegance.

Its slender silhouette suits a variety of hand sizes and shapes, especially those seeking a statement piece that remains understated in daily life. The low-profile setting also makes stacking with complementary bands effortless, offering versatility beyond the engagement moment.
