Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, elegant shadow that dances across the hand. This three-stone semi-set engagement ring offers a foundation to showcase an 8 x 4 mm marquise center, its pointed ends drawing the eye along the finger’s natural line.

Crafted from warm 14K yellow gold, the band is shaped with subtle tapering to balance the stone’s dramatic profile. Each prong is meticulously hand-finished to secure the diamond while maintaining a refined, low-profile setting that slips comfortably beneath gloves and daily wear. The artisan workshop’s attention to detail ensures smooth edges and a comfort fit that invites everyday elegance.

Choosing a lab-grown diamond for this ring reflects a commitment to ethical jewelry, reducing environmental impact without compromising brilliance or clarity.

This design suits those who appreciate architectural grace paired with classic warmth—ideal for slender fingers or anyone seeking a ring that complements stacking without overwhelming. The semi-set style allows you to select a center stone that matches your vision, making it a truly personal statement.

Resizing is available to ensure a perfect fit, crafted with the same care as the original design. Typical lead times reflect the bespoke nature of this piece, allowing for precise customization.
