Three Questions from the experts or those with personal experience who sensitive to their crystal's fields.

1, Crystals - How does quality effect them.

2, Weather, How do you protect crystals from the elements.

3, How do you fasten individual crystal together into larger clusters, or structures?

1, I am trying to get my head around how quality effects crystals specifically. Does a high quality crystal, more flawless internally, effect a larger area externally? I was offered a flawless crystal point, natural, handpicked by the shop owner from a trader. Will this effect as much of an area externally, as something with more flaws but lets say three times its size? Not speaking internally here, purely in the external world. If I want to build a crystal that effects a meditation area, am I better off picking larger pieces and placing them in a large crystal grid, or smaller flawless ones?

2, Weather, How do you protect from the elements outside, without compromising on its ability to amit a field or carry charge? What do you apply to quartz again for example to keep the elements from eroding or damaging it over time.

3, People talk about crystal cities. Well I am right at my first purchase now to begin to build crystal items to place outside, or inside. Starting small, and working up. 

Any methods you have for fastening crystals together, or linking them in this way to build for example a crystal structure, even a simple one like a tripod with three central pieces linked at the bottom. How would you do it, if you wanted to for example build something which carried charge, will or frequency, what materials would you link or bind them with?

Thank you for any help!
