Wire wrapping a labradorite pebble?

[AliMac]

Hi there. I've just acquired some labradorite stones, both oval flat pebble shapes. They are about 5 cm by 3 cm wide, and up to 1 cm thick. The nicest one has a more or less flat face but the back is quite rounded. My original plan was to use them as pendants, possibly hanging them on a chain maille necklace.

I'm not the greatest fan of the wire-wrapped 'look' (I find some of it a bit fussy) but it seems like a bezel wouldn't really work in this case. Can anyone point me in the direction of interesting wire wrapping (or an elegant solution??). I'm wondering about caging them somehow (actually I'm worried about making a dog's breakfast of the whole thing but that's another story!
