bronze earrings, with natural quartz pendants.
they have nice lever back hooks so that you don't have to worry about losing them or their backings. below the hook is a rhombus/diamond shaped link, then chains holding a bar with 4 clear stones.
the stones are naturally occurring quartz in a hexagonal pillar shape. they've been lightly polished/smoothed but that's it.
there may be slight inclusions of other stone, chips, or other flaws to them. 

these are made of natural crystals so each crystal looks different and earrings are of course going to be slightly asymmetrical.  
i try to pair them up as close to each other in shape/size as possible though.

rather heavy, at bout 20 grams for the pair (varies a bit)

earrings are ABOUT 4" total length on average (variation as much as .25" difference)
crystals are ABOUT 1.25" long each (again, give or take .25")
