Not as heavy and bold as Edison pearls, Oscillation gives a more comfortable option for large cultured pearls dangle earrings, in this case, post earrings.
Set in oxidized vintage repousse Sterling and oxidized Sterling body textured elements, they are comfortable to wear and have a fun pearl shape that makes them less usual  and add character to the pieces. Not too sober, not too crazy.
The post earrings secure with pression nuts -the curly ones- and I added the silicone tops to wear as an extra security measure -if like me you have long wild hair- or to wear instead of the sterling nuts if they feel more comfortable. -I personally love the silicone earring post nuts-
For measurements, the pictures where the earrings rest on the bust show their real size since it is a human size mannequin, some of the other pictures include a standard size business card, a USA quarter coin and a ruler to allow you to have as much idea of their real size as I possibly can provide. 
If you need some metric measurement just let me know.
