A stunning Victorian brooch in 14K yellow gold set with an oval black onyx and loaded with sparkling old mine cut diamonds in the form of a flower. The brooch is circa 1880, heavy and substantial, with an original tube hinge and possibly a later catch. I have not seen this kind of clasp on a Victorian piece before but it could be original. There are no signs of alteration. It it was replaced, it was done very cleanly. The brooch is 1 3/4" by 1 1/4". In excellent condition. Unmarked but tests a strong 14K. Guaranteed to be as described.
