Antique Victorian Gutta Percha Rose Locket

Antique Victorian gutta percha carved rose mourning locket. 

The locket has several minor condition issues. Original glass and frame are missing. Small chips at the hinge cutout. Locket opens and closes fine but is not flush on top and often requires manually lining up before closing. The hinge rivet pokes out a bit on one side. I believe replacing the rivet would fix the flush issue. 

Measures 1.8" x 1.55"
