Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, luminous silhouette that seems to stretch the hand with quiet elegance. This semi-set halo ring in 18K yellow gold frames a 10 x 5 mm marquise center, designed to cradle the stone securely while maintaining a low profile for everyday ease.

Crafted in Williamsburg, the band is polished to a soft sheen, its gentle curve resting comfortably against the finger. The halo setting enhances the diamond’s tapered drama without adding bulk, making it glove-friendly and ideal for stacking alongside other bands.

Each piece features a lab-grown diamond foundation, reflecting a commitment to ethical sourcing and sustainability without compromising brilliance or clarity.

Its slender silhouette suits hands seeking a refined statement—elongating fingers with architectural grace while offering a secure, comfortable fit for daily wear.
