These colorful dangle earrings are Southwestern and sterling silver (marked as such).  They include malachite and hematite stones.  The rest of the stones in the earrings may not be real, but we are not sure.  They have a maker's mark of "TK" in a circle (as can be seen in the photos below). 

When we got these earrings, they did not have earrings backs included, so the earring backs that we have included are, obviously, not original and do not match.  Of course, no one will see the earring backs when you wear them, and if someone is close enough to see them, he's probably not thinking about your unmatched earring backs...
