Adesea confundat cu Pirita ce are aceeasi compozitie chimica, dar un mod diferit de cristalizare, Marcasitul este mai fragil, sfaramicios si deschis la culoare. Era foarte pretuit de incasi care il foloseau in podoabe si il slefuiau sub forma de oglinzi folosite ca obiecte de cult in templul soarelui.
Se crede ca Marcasitul trezeste abilitatile senzoriale (mai ales clarviziunea).
Tipul de mineral: Sulfura de fier.
Culori: Gri-metalic sau auriu stralucitor.
Vindecare emotionala: Se spune ca amplifica stima de sine, ajuta depasirea complexului de martir, ii calmeaza pe cei speriati de spectrul saraciei desi au suficient de multi bani.
Folosinte practice: Purtati bijuterii cu Marcasit atunci cand calatoriti cu avionul ca sa va relaxati in timpul zborului.
La locul de munca: Se spune ca ajuta concentrarea si face ordine in haos.
Semnificatie magica: Util in procesul visarii lucide. Aceasta tehnica ne ajuta sa folosim somnul intr-un mod creativ, adica sa vizualizam realizarile pe care dorim sa le obtinem in viata de zi cu zi.
Afirmatie: Merg pe drumul meu fara sa fiu influentat de emotiile altora!
