Shold be no shortage of crystal pieces ideally suited t producingthe stuff - although it is a matter of horses for courses, so to speak and you wil find that the end material responds differently depending on its constituents - hence the question of what yu have in mind for it becomes significant not only because i am nosey and always interested in orgone tech, butalso may well be relevant in pointing you in the right direction.
eg, many mines throw out quartz as a by product that is basicly unwanted- this form of quartz is often quite respectable crystals that have grown toghther to form a slid layer, but when broken up for removel, you can still get some nice pieces but itis usually ilky and tends to be alittle trauatised b teh extraction process{ dynamite] - still good for setings but not for others, especially the more refinedapplicsations. if yo are planing resonating structures such as the so called "holy handgrenades", yu might want t loook fo rfairly well formed, 2inch or thereabouts clear quartz preferably cdouble terminated. on the other hand,if you are looking at a more sophisticate isturment yu might want to try the arcansas clear quartz, but if oyu want to get real funky, have a ply with the tetrahedral Herkiemer diamonds.
some forms are more prgrammable than others - the stuff frm the mines yu can walk around and pick up, and it wold be fine for cloudbusting, but not with accuracy or for more refiend uses. but then, Orgonite as such is a very variale materiel in itself and the constiutent can be varied dramatically to obtain difering functins structures etc.

no doubt you are full aware of all this, but if you want an acurate answer to yur question........

and you never know, i might just be able to help.
