Featured Costume jewellery marks, please help!

Good evening,
The below brooch bought it at a antique market as sterling silver. After I had it tested turned up is not sterling, but it has a 5 pointed crown mark, please see below. I wonder if anyone can recognise the maker’s mark. I only know Rolex to have a similar mark, I doubt this brooch has anything to do with Rolex.
The second item is a necklace, bought it few years back, I bought it as a designer necklace, but now I can’t remember the name. Does anyone recognise the maker’s name / mark?
Thank you.
Kind regards,
Simona

The necklace looks like it has an Alpaca mark, aka "costume". The pin is 1930s pot metal and rhinestone and I haven't a clue of whodunnit.

 

Thank you so much for your response.
I have managed to find part of the purchase description for the necklace“Modernist BRUTALIST
Matching Set with Tri-Tone metal”. It has matching earrings, I am looking for them, will post soon.
The signature starts with Al…., something tells me it’s not Alpaca.

The brooch it’s exactly as you described it, metal with rhinestones, nicely made brooch, thank you for identifying its age.

Kind regards,
Simona

 

The necklace is probably nickel alloy, brass and copper. A common word used for nickel alloy is alpaca, and it looks like a piece of the 'p' is missing, not uncommon.

 

Thank you.
Here is the purchase photo, can’t find the earrings any more.
Are there any similar necklaces to this one? I have searched the web and I could only find Abalone shell on Alpaca, nothing else.
I would appreciate if you could send me a link to anything similar.
Thank you.
Kind regards,
Simona

 

Modernist......... not Brutalist. imo

 

Ditto. May even be too recent to be considered Modernist.

 

I've seen the design here every so often.

 

Lovely, thank you so much.
I wonder if the crown in the brooch brings any bells?
Could it be Trifari?
Thank you.

 

I don't think so......

 

is there script in the upper right hand..

 

No, just the crown

 

Not a Trifari crown.
