Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This three-stone semi-set engagement ring in 18K yellow gold offers a refined balance between presence and wearability, designed to sit close to the hand without catching.

Crafted in Williamsburg, the band’s low-profile setting ensures comfort for daily wear, while the secure prongs cradle a 10 x 5 mm marquise center stone, ready to be paired with your choice of lab-grown diamond. The warm glow of 18K yellow gold complements the stone’s sharp geometry, polished to a smooth finish that feels natural against the skin.

Each piece reflects a commitment to ethical jewelry, featuring a lab-grown diamond option that reduces environmental impact without compromising brilliance or clarity.

Ideal for those who appreciate architectural elegance with practical design, this ring fits comfortably beneath gloves and stacks seamlessly with other bands. Its slender profile suits slender to medium finger sizes, enhancing the hand’s natural lines without overwhelming.

Resizing is available to ensure a precise fit, and our Brooklyn studio offers a pressure-free consultation to explore your custom diamond selection and final setting.
