Worth knowing
Quartz is genuinely piezoelectric: squeeze it and it produces voltage. That property runs watches and radios — one of the few crystal claims with physics behind it.
History
The Greek krystallos meant ice — they believed quartz was water frozen beyond thawing.
Practical
Caring for Clear Quartz
How to tell it is real
Glass is the common fake. Quartz stays cool to the touch; glass warms in the hand. Under magnification glass shows bubbles, quartz shows angular inclusions.
One general rule covers most mistakes: never store stones loose together. Diamond at 10 on the Mohs scale scratches everything else you own, and it does not need much contact to do it.
What that hardness means in practice
Matches quartz, so ordinary dust will not scratch it. Fine for rings, though decades of wear will show at the edges.
Traditional associations
Clear Quartz is traditionally used as an amplifier and a blank slate for intention. In chakra systems it is placed at the All, particularly Crown, and in elemental correspondence it is assigned to All.
These are cultural associations recorded across various traditions, not claims about physical effects. The composition and hardness above are measurable; this paragraph is folklore, and worth reading as such.
Questions
