it is an-intriguing piece. It might come to nothing, but I believe Italian smiths were assigned numbers, at certain time periods in history. Good Luck. I agree, it is a stunning brooch. Russ

Tiffany & Co ITALY by: Yvonne
Good Morning, Oh mY America. Congratulations on your beau ideal ruby brooch. Tiffany & Co - Italy?
Tiffany & Co have various signatures. Reflecting different times and places. Russia, New York, Paris, etc.
Take their Paris signature, for example, it's a unique mark, and only used on items exhibited during Expostion Universelle in Paris, France - ca 1900.
Well worth looking into. A clear image of the mark will be necessary. Any background information you might already have will also assist.
