Description: A group of quartz crystals with reddish-brown to black phantoms. The colouration of the phantoms is due to iron oxide trapped between layers of quartz growth. The biggest crystal reveals a partially exposed phantom, and some surfaces have patches with numerous minute quartz crystals.
The terminations have a few nicks and flaws, while there is some damage to the edges of the specimen.
The specimen displays well on a flat surface, all-round.
