ID request - Glass collection

[belgium*]

Hello dear members,

I am new to this forum and I would really appreciate your help!

I have a collection of glasswork, but I would like to know the origin country and the age of the pieces. 
Is it MURANO or BOHEMIA ??? All labels were removed!  

fine decorated with enamel, gold and (oil?) paint.

Some glasses are crystal glass?

And the main question, is this collection valuable or is it ***?

If you know something about a particular piece, please repost the photo along with your information. (age, origin, value, ...)

All info is appreciated!!!

Thank you, Kenny

All of these painted decoration remind me of Japan or mainland Italy relatively recent decorator items.

the same correct answer can be given to all of your posted questions.  Also, czech republic is a possibilty.  your pieces have little age and not a great value.
