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.
Please know that I cannot accept any requests for "live conversations" such as phone calls.I give my best answers in writing when I have time to think about them.Sometimes a "Chat box" will pop-up asking if you would like a live conversation.Please know it is not from me.
Please send me a clear photo of the lamp and its shade.
I also need to know the height.
To send photos you may use the "attach file" or "add file" link on your reply page or the "paper clip" found in the toolbar you see on your reply page.
Is it signed?
If not signed, is there a Tiffany mark of any kind?
If there is not a mark, how do you know that it is a genuine Tiffany lamp?
Many copies have been made.
On the base around edge or underneath.
The shade would be signed in one of the glass panes.
There is no hurry. There are thousands of value different from the originals if it is a copy.
