I Have to say it. I love this earrings. Bold but also different, asymmetrical but cohesive, with contrast in stones -polished moss blue kyanite and totally raw intense Mexican Opal- large but not heavy -I try as much as possibly can to avoid making heavy earrings, I find them unpractical for the modern wearer with more active lifestyles-
This "wing like" earrings are "similar enough and different enough" in shape and fun to wear, can work day or evening. 
They measure no counting the ear wire 7mm and 79mm
I add to pictures a standard business card, a USA quarter coin and a ruler to add a visual of sizes, to be sure, you can out close to your ear a credit card, business card, etc. and that might help, if need extra pictures I can set them on the real size human mannequin ears to show you how it could look. (I honestly had not the chance/time to do it this time)
