  • 1485 The Castle Hallmark

    The three-towered castle is the ancient hallmark of the Edinburgh Assay Office, applied since 1485. It represents the quality, strength and durability of the nation and of her goldsmiths' work.

The initials of the Assay Master were only replaced in 1759 when a thistle was used to denote sterling silver.

    In 1687 James VII granted the Incorporation its Royal Charter.
