Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it reveals a subtle drama that elongates the finger with quiet elegance. This semi-set halo ring in platinum frames an 8 x 4 mm marquise center, designed to balance brilliance with a low-profile setting that rests comfortably against the skin.

Crafted in platinum, the mounting offers durability and a cool, smooth finish that suits daily wear. The halo setting enhances the center stone’s pointed shape while maintaining a secure, streamlined fit that slips easily under gloves or rings stacked alongside it.

Each piece reflects a commitment to ethical sourcing, featuring a lab-grown diamond that combines clarity and sustainability without compromise. The semi-set design invites you to select a center stone that resonates personally, ensuring a custom engagement ring tailored to your vision.

Ideal for those who appreciate architectural lines and a refined silhouette, this ring complements slender fingers and adapts well to various hand sizes. Its comfort fit and modest height make it a practical choice for everyday elegance.

Should resizing be needed, our Brooklyn studio handles adjustments with precision, preserving the integrity of the setting. Typical lead times accommodate thoughtful customization without rush.
