Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its pointed ends drawing the eye along the finger with a subtle, elegant drama. This three-stone semi-set ring features an 8 x 4 mm marquise center, poised to be paired with your choice of side stones for a personalized narrative.

Crafted in 14K white gold, the mounting balances refined strength with a delicate profile. The low-set prongs cradle the stone securely while maintaining a sleek, comfortable fit that slips easily beneath gloves or daily wear. Each curve and angle is hand-finished in our Williamsburg studio, ensuring a smooth, tactile experience that honors artisan tradition.

Our lab-grown diamonds offer clarity and brilliance without compromise, reflecting a commitment to ethical jewelry that respects both people and planet.

Designed for those who appreciate a ring that feels as natural as it looks, this semi-set invites customization and layering. Its slender band and modest height make it ideal for stacking or wearing solo with quiet confidence.

Should you need resizing or prefer a consultation on side stone options, our Brooklyn studio welcomes you to explore possibilities without pressure.
