unknown Beautiful Heart Dangle Brooch 1.75” x 1” Gold Toned With Clear Stones

Beautiful Heart Dangle Brooch 1.75” x 1” Gold Toned With Clear Stones in excellent condition. Does have a hallmark on the back but I cannot decipher it. This is a well made brooch and came in a Faberge box, again I cannot decipher mark on the back. This is a very sturdy and very pretty piece.
