Gaillon 2,5 mm Wedding band Black gold

660 € or 3 x 220 €

    Modern and sophisticated, black gold is a remarkable option. It adds brilliance and personality to jewelry. As durable as traditional gold, it may change over time and requires maintenance to keep its intense color.

    • A timeless half-round wedding band: flat on the inside, gently rounded on the outside

    • 2.5 mm is a classic width for men, especially suited for slimmer fingers (around size 56)

    • Also available in a feminine version: Saint-Germain

  • The perfect half-band, always a safe bet. The Gaillon 2.5mm in 18K black gold offers a fine, understated design, suited for those with slender fingers, approximately size 56. Its ergonomic band is flat inside and rounded outside for added comfort.

    A word from our designer

    "Gaillon 2.5 mm is a fairly thin wedding band for a man and traditional at the same time. A good choice for small finger sizes in general - that is, for men, around a 56."

    The equivalent female model is available with the Saint-Germain.

  • Made in France, in our workshops
