Bundle 7 vintage Cameo brooches

vintage fun lot of 7 cameos. pix 2 and 3 are front and back of my favorite cameo (facing left) I believe it is hematite but sadly has 2 small cracks. one on the lower left and another on the upper right. could be a scratch but I think it's a crack. the remaining 6 are just fun faux Pearl's ect. 4 of them can also worn as necklaces with the backs having both a bail for a chain and a pin and the smallest one is a pendant only ( 2 are straight up pins)
