Yes, I love the contrast in between bone and kyanite, the rustic warmth from the bone and the cold beauty in the blue kyanite compel me, the finished elements always are attractive to my eyes specially in an asymmetrical style for earrings. One side warm and the other one cold... beiges and blues...
Set in solid copper with nickel silver prongs and alloy huggie ear wires, super boho and laid back and wondrous to wear with jeans. Ha!!! (I Have to make mine in silver/gold, I'm allergic to copper and base metals and iron even causes me Blisters... , can you even believe that???? I guess is nature's way to prevent me for hoarding More jewelry. Ugh.) 
The pictures show the earrings on standard business cards, aside a quarter coin, a standard steel ruler with metric and imperial measurement and on a real human size mannequin ear to provide you with an idea of their real size.
