Small antique pendants / brooch

These are three recent acquisitions from the flea market in Barcelona (Spain). I got them from Fira de Nautumismo which was held every Sunday morning at Placa Reial in the Gothic quarter.

• 

The first one is a pendant with a carved cameo.

• 

I really love this pendant. I think the seller says that this is from the art nuvou period.

• 

The pendant is not from a precious metal, but I admire the design. The cameo shows a carving of St Mary.

• 

The second pendant is a photo locket showing a gentleman. I am not sure about the age, probably late 19th century to early 20th century? I think it is of Spanish origin.

The third item is a brooch. It is made from a non precious metal, but it has a Spanish crown.

It also holds a picture of Jesus which makes me fall in love with it. I think it is definitely Spanish, however I am not sure about the age. Probably Art Nuovo or later?
