Pre Civil War Jewelry or Victorian ca 1894?

The way it was made, it look like very primitive, but the pendant is very elaborated.
I founding at a flee market. It was not look 'attractive, but I cleaned with silver cleaning solution.
I could not find any thing like that after researching thousands of antique sites.
In my no intent to sell it without adequate value. It belong to collectors and or/ museums.

PS In a Pictorial Archive book ISBN-13: 978-0-486-40103-4, p.63 , though, I found an example of a lace work, dated as 1894, I guess it is a collar. My brooch pendant has unbelievable resemblance of the major element of the lace design
