Banana Republic Crystal dangle earrings

These beautiful crystal earrings are the darker of the 2 pair. More of a charcoal-ish/grey hue. These have been dropped and the glass broke in such a great way that you cannot tell (it is on the back side of the left earring shown in the last 3 pics. You cannot tell from the front). I do not know what the post is. There is some internal imperfection near the cut out at the top but as you can see from the pictures barely noticeable. Stunning!!!
