The crystals are Madagascar quartz, raw points. This style of crystal occurs naturally and is not cut or polished. They are not usually considered to be jewelry grade... and that's what I think makes them spectacular. They have a very rough/mottled quality to them that I find infinitely appealing.
Oxidized brass french hook style locking lever back earwires.
Length may vary by pair from 2" to 2.5" from the top of the wire to the bottom of the crystals. Of course, each pair will be matched in length, you won't receive a wonky pair with one short and one long...unless that's how you want them (please convo if you prefer wonky).
These earrings are made to order and may vary slightly from those in the image above. Please expect slight variations in the length and faceting of each set of crystals and slight differences in the surface of the brass casings. Each is a salvaged fired bullet casing, and will differ slightly with small scratches, dents, and levels of oxidization.
