Glass shades with brown leaf vines decorating it. I have two of them

Hi! Someone is offering me this French Gobelin; he says it's a Dubon brand from France and made during the second half of the XX century.
The frame is made of wood, gold leaf, and plaster. No glass. It measures 200 cm height, 90 cm tall.

My questions are:

Does anyone know more about this brand?
Do you all think that antique was made during the second half of the XX century?
How much does it value?

I am trying to get all this info before buying it to ensure I am making a good choice and not overpaying it.

Thanks!

Crystal vade. Pretty heavy, no makers marks on it that I can find! Alternating pattern around it. Star shape on bottom

Small rose shaped candle stick holder. Bottom says Apilco and FD Chauvigny in gold writing. Also has a gold symbol on the side. Looks like the theosophical society symbol or something similar.

This has been in the family for a while, but unfortunately anyone who would know anything about it is now gone. I don't seen any maker's marks on the reverse or undercarriage. I'm hoping for any information at all--approximate age, value, anything. Thank you in advance!

34 x 26 GLASS portion.
I have very little history.
Bought local in alabama.
Was said to be an antique?
Would Iove any information at all.
Style/ type/ technique?
Muti colored.
No chips. No cracks.
Thank you.
