Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated facets of a marquise diamond, it casts a slender, dramatic sparkle that seems to dance along the finger. This semi-set halo engagement ring frames a 9 x 4.5 mm marquise stone, ready to be paired with your chosen center, its shape lending a graceful elongation to the hand.

Crafted from 18K white gold, the mounting features a low-profile halo setting designed for everyday wear. The band’s smooth finish and secure prongs ensure comfort and durability without excess height, making it glove-friendly and easy to stack with complementary bands.

Each piece reflects our commitment to ethical jewelry, showcasing lab-grown diamonds that offer clarity and brilliance with a lighter environmental footprint. The semi-set design invites personal choice while maintaining the precision and polish of a Brooklyn studio creation.

Ideal for those who appreciate architectural elegance paired with practical design, this ring suits slender to medium finger shapes and adapts well to resizing if needed. Its balanced proportions and subtle halo enhance the marquise’s distinctive silhouette without overwhelming the hand.
