A sweet little late Victorian heart, with a central pink coral stone. 
I bought this as a charm, but I imagine it was once part of another piece. 
We have replaced the jump ring with a 5mm, properly soldered one in our usual way. 
Tested as 15ct gold (jump ring is 9ct) 
Weight approx 1.67
Total drop approx 18mm
Width approx 10mm
Very good antique condition.- some wear to coral.
