Hard to measure, as the curve prevents measuring accurately. End to end, without straigtening the curve is 80 mm, but max hanging length is 50 mm. Very, very fine sterling box chain, Open jumpring, and metal post. I personally find these with the curve more comfortable. If you haven't seen these, these are the hottest thing since the chandelier earring - especially with the younger crowd. Just add a crystal and you are good to go.

By the pair.
