Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow that draws the eye along the finger’s natural line. This semi-set halo engagement ring foundation in platinum offers a refined stage for a 12 x 6 mm marquise center, designed to balance presence with everyday ease.

Crafted with a low-profile setting, the halo gently embraces the center stone, enhancing its tapered drama without adding bulk. The platinum band is polished to a smooth finish, ensuring a comfort fit that sits close to the hand and resists snagging—ideal for daily wear. Each mounting undergoes meticulous inspection in our Williamsburg studio to meet exacting standards of symmetry and durability.

Our commitment to lab-grown diamonds reflects a thoughtful approach to ethical jewelry, reducing environmental impact while delivering exceptional clarity and sparkle.

This ring suits those who appreciate architectural elegance paired with practical design—its slim profile complements slender fingers and layers seamlessly with other bands. The halo setting adds subtle dimension, perfect for stacking or wearing solo with gloves or bare hands.

Should you wish to adjust sizing, our in-studio experts provide precise resizing to ensure a comfortable, lasting fit.
