Hello,
Thanks for your post.
I really don't know about Princess House, so I can't tell you if it is, or not.
The best I can do is describe it for you...
It is cased glass with aventurine. As for a maker, have no idea. These are very common on Ebay and have many shapes... Maybe someone in the forum has seen one with a label of some kind and can be more helpful.
Thanks again.
Javier
