Lab-Grown Diamond Engagement Ring
When light catches the sharp corners of a 9 x 9 mm Asscher cut, it reveals a quiet geometry—an architectural dance of step-cut facets that draw the eye inward. This semi-set five-stone engagement ring in cool platinum offers a refined foundation, inviting your choice of a center diamond to complete its poised silhouette.
Crafted in Williamsburg, the platinum band is polished to a mirror finish, its low-profile setting designed for everyday grace and comfort. The five-stone arrangement balances bold presence with subtlety, allowing the center stone to command attention without overwhelming the hand. Each prong is meticulously shaped to secure stones while maintaining a sleek line that slips easily beneath gloves or alongside stackable bands.
Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, ensuring clarity and brilliance with a lighter environmental footprint. This ring suits those who appreciate architectural elegance paired with modern sustainability.
Its comfort fit and balanced weight make it ideal for daily wear, especially on slender to medium fingers where the square shape elongates the hand. Should you wish to adjust sizing, we offer precise resizing to maintain the integrity of the setting.
