Vermeil is sterling silver coated with gold. To be considered vermeil, the gold must be at least 10 carat (42%) and be at least 2.5 micrometres thick. Vermeil was used in the 1940`s when resources were limited and this is part of it`s appeal to collectors.
Adolph Katz was design director at Coro from 1924 and made major contributions to the company`s success in particular Jelly Bellies & Duettes.
