Necklace:

I am not sure the materials. The horse appears to be some kind of metal, the beads I think are plastic made to look like rocks, the cord is like leather or faux leather or rope. Necklace string measure about 31" long. Top of horse to bottom of blue bead under horse is about 2.5" tall. and about 1.3" wide. The additional small blue bead, medium blue bead, maroon and silver beads measure about 2" on either side.

Earrings:

They measure about .7" wide by .7" tall not including the dangle part, just the horse. ( I added rubber earring stops after the photos were taken so those are included as well.)
