TPM56CD5: A rarity for Almadén, not only because of the minerals it contains but because of how they interact with each other. Very dark vermilion Cinnabar crystals are deposited on a matrix of 'piedra frailesca', but mostly covered by a druse of Quartz crystals with Cinnabar inclusions that make the Quartz look like it has iron oxide staining but which is really caused by the reddish mercury sulfide.
This specimen comes from the former collection of Andrés Jiménez Shelly.
