Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, elegant shadow across the hand. This semi-set solitaire ring invites you to select a center stone that balances dramatic taper with refined brilliance.

Crafted from warm 14K yellow gold, the band is shaped with a subtle comfort fit, its smooth interior contouring gently to the finger. The setting’s delicate prongs rise with artisan precision, designed to cradle an 8 x 4 mm marquise diamond securely while maintaining a low profile that slips easily beneath gloves or daily wear.

Each piece is finished by hand in our Williamsburg studio, where careful inspection ensures the metal’s rich hue and the setting’s structural integrity meet exacting standards. The choice of a lab-grown diamond aligns with a commitment to ethical jewelry, offering clarity and sparkle without compromise.

This solitaire’s slender form suits those who appreciate a statement that is both bold and wearable—ideal for slender fingers or as a striking stackable band alongside wedding rings. The semi-set design allows you to personalize the centerpiece, making the ring uniquely yours.

Resizing is straightforward, handled delicately in-studio to preserve the band’s seamless finish and comfort fit.
