Help dating pendant necklaces, cameo brooch and novelty sword/cutlass tie clip lot

[Pinkcoke]

The two necklaces and cameo brooch all came from a bereavement lot so I'm thinking they are probably within the same decade of each other, 70's or 80's? I've just thought the celtic style one could be a Miracle design. The brooch is a bit more interesting, gilt silver metal, I think its some form of plastic, but the lady on the front has definite carving marks on her neck, so has this been done to imitate a genuine shell cameo?
The sword tie clip is fun, it has a gap in the middle so that when worn, it appears as though the sword goes through the tie. Even more so because the back says Stratton IMITATION! I mean, why bother putting Stratton on there if you're going to tell them it's not? or was 'imitation' meant to be a range by Stratton? I haven't got a clue on how to date the tie clip so any hints or tips would be good. I'm not thinking it's terribly old.

I think the pendants and brooch are all 60s/70s; the first seems to be an imitation fire opal? and that particular cameo lady is very common in 60s/70s jewelry, in brooches, pendants, etc. I agree she's meant to mimic a shell cameo, and is plastic.

I can't see the writing on the tie clip (nor do I know much about the Stratton company), but I'd guess it's early 50s. Anson patented this particular sword design in 1948:

and Swank made quite a few versions (see the pic of mine with MOP handle below!) The width is a giveaway to date, since it would need to be worn with a wide tie, which were out of style by the mid 50s!
