Heirloom remodelling

Keep the stone.
Change the story.

What we keep,
what we melt.

Nothing leaves the building. The stone is lifted in front of you, cleaned, weighed and graded again. The old gold is assayed and credited against the new ring.

  1. Kept

    The stone

    Lifted
    day 1
    Re-graded
    GIA or IGI
    Re-polish
    if chipped

    Old cuts are often better than they look. Under the loupe most need nothing but a clean.

  2. Credited

    The gold

    Assayed
    on the bench
    Paid at
    spot − 8%
    Or recast
    into the band

    Keep it in the new ring if it means something, or take the credit. Either is fine.

  3. New

    The mark

    Hallmark
    London assay
    Engraved
    both dates
    Made in
    6 weeks

    We engrave the first date beside the new one, inside the band, unless you ask us not to.

What is the gold worth?
