Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a confident gleam that stretches across the finger. This semi-set engagement ring foundation in 18K yellow gold offers a sleek, modern-minimal frame designed to highlight an 8 x 4 mm marquise center stone of your choosing.

Crafted with precision in Williamsburg, the band’s smooth finish and low-profile setting ensure comfortable wear and effortless stacking with other rings. The yellow gold’s warm glow complements the marquise’s tapered points, creating a refined balance between structure and softness. Each piece undergoes meticulous hand inspection to guarantee flawless craftsmanship and durability for daily life.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and brilliance with a significantly reduced environmental footprint.

Ideal for those who appreciate architectural elegance paired with understated confidence, this mounting suits slender to medium finger sizes and pairs well with both delicate and bold accent stones. Its streamlined design slips easily under gloves and fits comfortably for everyday wear.
