This destash has a couple of fun things and a couple of prototypes.
The cage element can hold a stone -and be secured at the bottom with colorful threads, silk sari, wire (be sure to hide the tips or make ball tips if you seure the end with wire to prevent injuries/discomfort!) or worn as is as earring in an asymmetrical set or as solitaire earring; the other prototype is the bullet "container" where two bullet cases -from fired bullets, is no powder, no danger, are just the dress that covers them and it jumps out when a gun is fired, like in the movies where the police finds the "casings"/shells.- It is NOT waterproof so don't wear as pendant with your allergy pills in it and go surfing!!! You can carry the allergy pills IF you are not planning swimming with the pendant on, LOL. 
The other two elements are an empty bullet case -that can be used to glue a quartz spike, a long stone, textiles, etc. and a river stone that I set in brass and had buried for a while to give that "excavated element look". -Still smells like dirt!!! IF you want to remove any possible debris/patina, just wash with dish soap and a brush-
Fun and weird, I know. ;)
They measure, stone no counting stem 45 x 31 x 20mm, 76 x 1mm cage, 78 x 14mm bullet container pendant, 44 x 9.5mm bullet setting to glue stone spike.
