What a nice group of pieces. Those all look good to me. The cameo pieces are authentically carved and not moulded.
Just a couple of pointers for you. Take a closer look at the facial features on the three pieces in the centre row. Preferred portraiture styles had some interesting changes over time. The first and last pieces in that row have very classical 'roman' noses, which is a good indication that they are 19th century (ie likely Victorian). By contrast, the middle piece has a very romanticised 'snub' nose which is turned up at the end. In combination with the other features and the hairstyle, that's usually a good indication that the piece is 20th Century rather than 19th Century and so I would think that one is probably Edwardian rather than Victorian.
Secondly, for brooches, if they have a c-clasp where you can see the pin protruding beyond the edge of the setting (top left and middle left), that's also a good indication for Victorian and usually not later than about the 1880s.
Thanks for showing.
