i had a look around etsy and found actually some cheap powder/course grain seller...I would be cautious looking for crystals from China. They're known best for manufacturing synthetic materials, not digging raw/rare materials. India is a much better source of natural gems, I outsource mine from Etsy, where are many reputable sellers.
i there bought some pink tourmaline and flourite 0,5-1mm grain for 13 euro for 50g each
pink tourmaline to test it against the black one i have (tho, i have read that black tourmaline is more effective)
and flourite to test my theory about the non-conductor property
flourite is "conducting" but its so high resistance that it "looks" like no connection ( probably some mega ohms, therefore the name, non-conductor, i guess we could also look at this from a "bad isolator" standpoint)
but i wonder if a rca plug filled with a tourmaline and flourite mix could actually interact with eachother because of that
i still have to test the same with shungite powder, it actually can conduct but i need to isolate the plus pole on my next rca caps for it
i also bought some UV glue in different colors to see how fancy i can get the rca caps...
i also found some 8mm messing round plates 1mm on thick on aliexpress to close the end of RCA caps EMI/RFI safe, i think i will either screw the plate in place with the right connector and fill the gaps with some copper tape or will try to solder them if it works ok... then use the UV glue in different colors to give them a color on the end... (white for quartz, green for phenit, orange for topaz etc
i was actually thinking about this and if i would sell chinch caps... its probably best to offer them in different colors with just one crystal each (or maybe some special ones like shungite+tourmaline or such)
IMO mixes are hard control... it probably is hard enough to get the same effect from quartz from two batches and it would actually allow to mix and match the different crystal plug (for the enduser) to create his own "mix"
also the testing with mixes is way harder ... i kinda wanna keep it simple, specially because the tourmaline plugs work pretty well on their own
atleast personally even if someone claims to found the "perfect mix" in the end you get what you get, either you like it or dont, individual rca plugs seem much more universal here
the only thing i havent found yet is the perfect cheap rca plug for this... these here look reasonably https://de.aliexpress.com/item/1005004571617873.html and they have a real hifi chinese brand behind them, no obvious knockoffs
