This popular style which originated in the '70's has been rediscovered. The post at the end is threaded through the piercing and pulled through to wherever you like it. And yes, the chain goes through the piercing. Have the beaded part hanging longer or shorter - your choice - no backings to deal with. Note that these are not suitable for large or stretched piercings unless you use a stopper (not included).
The Ear Threads shown here are Sterling Silver with the Peridot (Bead # 82).
If you have more than one piercing, you may want to try threading them through the lower piercing, then the second one - or vice versa? They are shown here with Burgundy Pearls (Bead # 24).
Threaders are now available in 14 Karat Gold Filled as well as Sterling Silver.
