Most stone is quartz or contains quartz. Quartz is nothing more than silicon dioxide and it makes up most of the “rock” that makes up the Earth. Pretty sure bet that perhaps though that gravel isn’t crystalline quartz, there’s a dose of quartz in there.
The only thing I could see being less good about sand is that it contains impurities and may not be as regular a crystalline structure as a piece of quartz crystal but in large quantities like that hill, this probably doesn’t matter much.
Been meaning to make a TB using maybe a teaspoon or two of washed kiddie sand (which seems to be really pure, clean sand and under a microscope a lot of it is clear/transparent) to see what the energy signature of it looks like as compared to an equivalent device made with a piece of quartz crystal but haven’t gotten that far down on my to-do list yet. Wouldn’t it be a hoot if a teaspoon of kiddie sand works well enough to use in place of a quartz crystal chip! Of course, I’m not making any such claim at this point as I haven’t done the experiment yet but I’m sure the device will work – just not sure how well till I make it.
Pretty much any “rock” thats transparent to mildly translucent is most assuredly quartz. If you break it up and look at the cleaved surfaces and it has that kind of irregular shiny but not mottled appearance, its pretty well crystalline and VERY usable in orgonite. If its shiny but has a kind of mottled appearance as if it were made of smaller bits pressed together, its not wholely crystalline and not quite as good to use. Granite is like this as an example. That “speckly” appearance is a dead giveaway.
Topaz, citrine, amethyst, garnet, ruby, emerald, peridot, rose quartz, sapphire, carnelian, and on and on are ALL forms of quartz. ANY of these will work just fine in orgonite in place of clear quartz crystal. Look around your area. You might be amazed at what you find.
You may even luck out at a landscaping supply place or decorative stone place. Better vendors carry boulders of rose quartz. Though its usually of lesser quality being veined with white quartz, maybe a little iron or other impurities, in a pinch, this stuff will work also. I picked such a boulder up (I’d consider a 54# “rock” a boulder – wink) for a whopping 35 cents per pound! Not that I’d use this exclusively as I have good Arkansas quartz crystal chips to use but I toss a small piece in with each device to add a little more love. Funny thing is, because of the impurities (tiny bit of iron and what looks like a little mica of all things), somehow the energy signature of this stuff feels more masculine that rose quartz normally does (rose quartz feels more feminine to me – that yin/yang energy thing). Regardless it has a very pleasant energy signature and for this price I can afford to toss a chickpea sized piece of this in every TB I make.
To me the energy signature of a TB made with just a quartz crystal chip and aluminum has a very cold feel where with the piece of rose quartz it feels warmer and more appealing – like the difference between a cold white fluorescent bulb and that of a warm white bulb. Maybe its just me but I feel better about tossing devices with a warm energy feel to them – have a funny feeling the energy may be more appealing to the wild life in the area and rose quartz being a love stone, there’s no such thing as too much love (wink).
