Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc of brilliance that seems to whisper of quiet promises. This semi-set halo engagement ring foundation in platinum frames a 10 x 5 mm marquise center with a subtle circle of pavé, designed to amplify sparkle without overwhelming the stone’s graceful taper.

Crafted in Williamsburg, the platinum band offers a cool, weighty feel that balances durability with refined elegance. The halo setting is low-profile, ensuring the ring sits comfortably beneath gloves or daily wear, while the secure prong arrangement protects the pointed ends of the marquise. Each piece undergoes meticulous hand finishing and inspection to meet exacting standards.

Our commitment to ethical jewelry shines through the use of a lab-grown diamond center, chosen for its clarity and sustainable origins, reflecting a modern approach to love and responsibility.

This design suits those who appreciate a ring that elongates the finger and pairs effortlessly with stacking bands or a wedding band. Its comfort fit and modest height make it ideal for everyday wear without sacrificing presence.
