Hallmarking in the United Kingdom dates back 700 years and represents
the oldest form of consumer protection in the United Kingdom.
A
hallmark indicates Who, What, Where, When:
- Who made the article
- the sponsor's mark
- What the precious metal content is
- the fineness mark
- Where it was hallmarked
- the Assay Office mark
- When it was hallmarked
- a unique letter mark for each year
As such all items crafted by our
Goldsmith will bear the
unique AA Thornton sponsor’s mark.
