Lab-Grown Diamond Engagement Ring

Imagine the quiet moment when a marquise diamond catches the light, its elongated silhouette casting a subtle, graceful shadow across your hand. This semi-set engagement ring foundation invites you to choose a center stone that will become a personal emblem of your story.

Crafted from 18K white gold, the band offers a cool, luminous backdrop with a delicate profile that balances presence and comfort. The slender shank’s gentle curve ensures a secure, low-profile fit that slips easily beneath gloves or stacks seamlessly with other bands. Each piece is meticulously finished in our Williamsburg studio, where hand polishing and precise inspection guarantee a refined surface and lasting wearability.

Our commitment to ethical jewelry is reflected in the choice of lab-grown diamonds, which provide exceptional clarity and brilliance while minimizing environmental impact.

Designed for those who appreciate understated elegance and a touch of vintage-inspired drama, this mounting suits a 10 x 5 mm marquise stone that elongates the finger and lends a distinctive, architectural grace. Its solitaire setting emphasizes the diamond’s unique shape, allowing light to dance freely across its facets.
