Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of an oval lab-grown diamond, its elongated silhouette casting a subtle glow across the hand. Nestled within a delicate halo of petite stones, this platinum engagement ring balances quiet romance with refined craftsmanship.

Each element is meticulously crafted in our Williamsburg studio: the low-profile halo setting secures the 6 x 4 mm oval center with precision, while the polished platinum band offers a cool, smooth feel against the skin. The comfort fit ensures it wears effortlessly through daily moments, from morning coffee to evening strolls.

Our diamonds are grown with care, reflecting a commitment to ethical jewelry that honors both beauty and sustainability. The oval shape’s soft elongation flatters a variety of hand sizes, making it a graceful choice for those seeking understated elegance with a whisper of vintage charm.

Should you need a custom adjustment, resizing is handled in-house with attention to preserving the ring’s delicate balance. Whether layered with other bands or worn alone, its subtle profile invites versatile styling without overwhelming.
