Each Hoop Earring measures 7.5 cm long.
The whole hoop is textured wire, making the silver sparkle all over when wearing. I have soldered a 20 gauge post, which is the standard earring post size onto one of the ends and on the other a small ring to be able to close the hoop. How the hoop closes once in your ear is by threading the ear post, which is bent into an "L" shape into the ring soldered on to the other end of the hoop.
The thickness of the hoop is 16 gauge solid sterling silver rod and will not kink, however it can be bent out of shape but you can bend it back as long as the original damage is not so severe. If you don't know, just contact me with a picture and I will help you.
Due to the handmade process, each pair of earring will be slightly different from the ones pictured.
