Cat hat pin and 1930s elephants brooches

Interesting hat pin and two elephant brooches from the lot I recently bought online form Czech republic. Unmarked beauties.
I would say the 2 elephants are from 1930s, and their condition is very good, no stone missing, they look like new - someone took good care of them!
The cat hat pin is a lovely treasure with clear and emerald rhinestones. I love its design! It is in worse condition, one stone is missing. I would like to hear your opinion about when this was made. When I see the stones I think paste.
