Asymmetrical and with Industrial style, Pleistocene holds as "stones of choice" two surprising elements, a fossil wooden shard and an orthoceras part. 
The fixed earwire, soldered to the top, holds two tubular sterling oxidized forms that keep the organic look of the wrapped wire inside at bay and from it the two "stones", rustic and brutal, with the force that fossil elements seem to emit, the resilience that is capable of defying time.
Solid oxidized Sterling silver, One of a kind.
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.
