Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This three-stone semi-set ring in 18K yellow gold offers a refined foundation for a 12 x 6 mm center stone, designed to sit close to the hand with a low-profile setting that balances presence and comfort.

Crafted in Williamsburg, the band is meticulously shaped for daily wear, its smooth interior ensuring a comfort fit that slips on effortlessly. The three-stone arrangement allows for personalized selection of side stones to complement the marquise’s distinctive, tapered brilliance, while the secure prong setting holds each gem with precision and care.

Each diamond is lab-grown, reflecting a commitment to ethical sourcing and sustainability without compromising on clarity or fire. The warm glow of 18K yellow gold enhances the marquise’s vintage-inspired elegance, making it a versatile choice for those who appreciate subtle sophistication.

Ideal for hands that favor elongated shapes, this ring’s slender profile layers well with other bands or stands alone with quiet confidence. Its design accommodates resizing and routine care with ease, ensuring a lasting fit through life’s moments.
