I have done research and found an online shop where i could buy crystals. Dad said no and said he’s seen ones exactly like that at a local brick shop where they can be bought buy the bucket, rather than $3.50 per crystal. Would these be suitable for crystal healing? Would they have the same effect? Useful answers only thanks, no skeptics. Anything rude and your answer will be reported. Otherwise please help, i don’t know whether they’d have the same effect, thanks in advance.
