Hello and welcome! My name is Doris.
I have been an antiques collector, dealer and appraiser for over 56 years.
I will be pleased to help you.
I have researched your question for very, very old objets d'art.
Most are in museums and are priceless.
The design of your piece does look as though it came from the main areas of Islamic religions.
Your piece should be in a museum where it can be cared for properly.
My experience with such beautiful such ancient objets d'art is that they are worth as much as $35000-40000.
You might get your best price by donating to a museum and taking a tax deduction.
I would not trust it to leave your hands for an auction house to sell.
I hope I have helped you.
