What is Marcasite?

Marcasite has the same chemistry as pyrite (iron sulphide) but a different crystal structure, often forming spear-shaped or cockscomb crystals with a paler brassy colour. It is less stable than pyrite and can slowly crumble in humid air.

Fun fact: the tiny sparkling stones in vintage "marcasite" jewellery are actually pyrite, which is more durable.

Rituals & pairings

Pair Marcasite with a protection & cleansing ritual

A traditional cleansing ritual for resetting your space and feeling protected.

Traditionally paired with: White sage or palo santo smudge sticks · Dragon's blood, frankincense or myrrh incense · A white or black candle

  • Open a window, then light a white sage or palo santo stick and let it smoulder.
  • Gently waft the smoke around your crystal and through the room, corners first.
  • Light a white candle and place your crystal beside it while you set a simple intention, such as "This space is calm and protected".
  • Finish with frankincense or dragon's blood incense and let it burn down safely.

Safety: never leave candles, incense or smudge sticks burning unattended, keep them away from children, pets and anything flammable, and ventilate the room. Rituals are shared as tradition, not as a treatment.
