Fantastic LARGE antique mid Victorian authentic Whitby Jet black mourning brooch pin. Faceted large egg shaped piece on a big wide half cylinder with dangling faceted balls that are suspended by large round chain links. The chain links are also made of Whitby Jet. Measures 2" x 2" x 7/8". At the top, is a large drill hole opening, apx. 3/16" in diameter, for a chain, to wear as a necklace if desired. Brass pin stem assembly with wide tube hinge and simple "c" clasp. In outstanding well babied condition. This is guaranteed to be Whitby Jet, and dates from between circa 1840 to 1880. Extremely well cared for, a VERY nice example of antique Whitby Jet.
