I can understand worshipping stones. Crystals are said to have energetic powers, particularly by psi sensitive people. Like that one autistic kid in the telepathy tapes that collected crystals.
Once while messing with a howlite crystal I could palpably feel it pulling out and consuming some kind of obstruction from my crown, it felt like grass being pulled out of my forehead, and absorbing it.
Those 'elements' then 'disintegrated' into what felt like a void in the crystal. It worked for 2-3 days, I would carry it around, but it only had this effect when I physically handled it, not just kept it in my pocket. I had never experienced or heard of anything like that before.
The crystal was dyed purple by the craftsman, I received it as in a set of crystals as a free gift after a missing necklace shipment (one of those vortex energy filaments).
Without any exposure or handling beyond a couple of days, nor any sun exposure, it gradually lost its colour on its own. I then bought a howlite palmstone and felt even stronger soothing effects from that, stronger than drugs. However I had to deliberately direct my energy through it, sort of like a 'resonator' in a circuit. It makes sense that they would become the centre of a religious cleansing rite. No one really knows what the composition of the ka'ab meteorite is, but it seems to be some sort of glass crystal.
Priests and sacral-kings have always revered crystals and gems for their magical and restorative powers. The Israelite priests would have 12 on their chests, and it was imitated from Egyptian priests, I believe.
