Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that dances along the finger. This semi-set engagement ring in 14K yellow gold offers a poised foundation for a 7 x 3.5 mm marquise center, its tapered shape lending a refined drama and elongating the hand with subtle elegance.

Crafted with a modern-minimalist ethos, the band’s clean lines and delicate accent settings emphasize clarity and architectural balance. The low-profile mounting ensures comfortable daily wear, while the warm glow of yellow gold complements the diamond’s crisp facets. Each ring is meticulously finished by hand in our Williamsburg studio, inspected for precision and durability.

Choosing a lab-grown diamond aligns with a commitment to ethical jewelry, reducing environmental impact without compromising brilliance or quality.

This design suits those who appreciate structured simplicity with a confident edge—ideal for stacking or wearing solo. Its slender profile fits easily beneath gloves or sleeves, making it a versatile companion for everyday life.

Resizing is available to ensure a perfect fit, and the semi-set style invites you to select a center stone that reflects your personal story.
