The Dingwall Sterling mark appears on silver items produced by William B. Dingwall, a Canadian silversmith known for high-quality craftsmanship in the early 20th century. The mark includes the name “Dingwall” and the word “Sterling,” confirming that the piece is made of genuine sterling silver. Dingwall was active primarily in Winnipeg and is recognized for both flatware and presentation pieces with elegant, often hand-finished detailing. This mark is especially valuable to collectors of Canadian silver, as Dingwall's work is less common than larger international firms. The Dingwall Sterling mark serves as an important identifier for verifying origin, material, and regional craftsmanship.
