A celebration of brilliance and balance, the ‘ONE’ ring features a commanding ~0.5ct round-cut lab-grown diamond at its center, paired with a graceful half-eternity band of ten brilliant melee diamonds. While the bold center stone evokes timeless elegance, the open-ended design introduces a sense of movement and modernity.
Slightly raised above the ring’s arc, the diamond’s setting emphasizes its presence—allowing light to reflect from every angle and amplifying its natural radiance.
Refined yet expressive, this ring is for those who desire sculptural luxury with luminous impact. A diamond certificate is included for the ~0.5ct stone.
