Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous beam across the hand. This 10 x 5 mm center stone, set in cool 14K white gold, balances architectural precision with a modern-minimalist spirit.

Expertly crafted in Williamsburg, the ring features a low-profile setting that secures the marquise with delicate prongs, allowing light to flood the stone’s pointed ends. The smooth band, finished to a soft comfort fit, wears effortlessly day to day while the subtle accent stones add a refined sparkle without distraction.

Each diamond is lab-grown, offering a clarity and brilliance that honors ethical sourcing and sustainability without compromise. The cool white gold complements the diamond’s icy fire, creating a seamless union of metal and gem.

Designed for those who appreciate clean lines and confident structure, this ring suits slender to medium finger shapes and layers beautifully with stackable bands or wedding bands of similar profile. Its low height ensures glove-friendly wear and ease of movement.

Should you need resizing, our Brooklyn studio handles adjustments with care to maintain the ring’s integrity and finish. Typical lead times reflect our commitment to meticulous handcrafting.
