Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of this marquise diamond, it reveals a striking interplay of brilliance and subtle drama. The 9 x 4.5 mm center stone is framed by a delicate halo, enhancing its tapered points while maintaining a refined profile.

Crafted in cool platinum, the setting balances durability with a smooth, low-profile design that rests comfortably against the finger. The halo setting is precisely hand-finished in our Williamsburg studio, ensuring each prong secures the diamond with quiet strength and minimal bulk—ideal for everyday wear.

Our commitment to ethical jewelry is reflected in the lab-grown diamond’s clarity and origin, offering a sustainable alternative without compromising on radiance or craftsmanship.

This ring suits those who appreciate architectural elegance paired with practical comfort. Its slim band and low height make it glove-friendly and stackable with other bands, while the marquise shape visually elongates the hand for a graceful effect.

Should you need a custom fit, resizing is available with careful attention to preserve the setting’s integrity. Typical lead times reflect our bespoke approach, crafted thoughtfully in Brooklyn.
