Your pitcher in Amberina I am sure is a 1970/80s reissue from an old mould.
I have a 2004 Mosser Glass Catalogue and on page 10 there are five pieces shown one is a pitcher like yours.
Mosser's name for this pattern is Diamond Classic #301 and is in crystal carnival.
I thought it may have been an original Indiana pattern, but I have searched there patterns and cannot find it.
Indiana made glass for Tiara Glass from old moulds so it is still a posability
Mosser Glass have a web site you could email them and ask if is it one of theres.
