Rose From Beauty And The Beast

rose from beauty and the beast
What is that jar called that has the rose in it from Beauty and the Beast?

The upside down jar thing from beauty in the beast with the rose in it? Is it called a jar? When I think jars I think of jam jars which doesn’t seem right. What is the proper name for that type of jar? What is a prettier name for it?
