Co je křemen?

Křemen je nejrozšířenější minerál na Zemi a základ mnoha hornin.

  • chemické složení: SiO₂ (oxid křemičitý)
  • tvoří typické šestiboké krystaly
  • nachází se samostatně i jako součást jiných minerálů

Křemen je vlastně velká rodina kamenů, do které patří například:

Dokonce i obyčejné zrnko písku je ve své podstatě křemen.

Co je křišťál?

Křišťál je nejčistší a čirá odrůda křemene.

  • průhledný až lehce zakalený
  • často obsahuje inkluze (např. rutil, turmalín)
  • tvoří krásné, pravidelné krystaly

Je ceněný pro svou:

  • čistotu
  • univerzálnost
  • a v esoterice i jako „nejsilnější energetický kámen

Hlavní rozdíl jednoduše

Jinak řečeno:
Každý křišťál je křemen, ale ne každý křemen je křišťál.

Zbarvení a vzhled

Křemen obecně:

  • čirý, bílý, růžový, fialový, žlutý, hnědý…
  • barvu ovlivňují příměsi dalších prvků

Křišťál:

  • čirý jako sklo
  • někdy jemně mléčný nebo s „závojem“ (inkluzemi)

Proč jsou tak oblíbené?

  • křemen nabízí nejširší škálu barev a variant
  • křišťál je nadčasový, čistý a univerzální
  • oba patří mezi základní kameny ve špercích i esoterice
