This specimen features spires of chalcedony covered with sparkling quartz crystals. The chalcedony cores of these spires include some orange and pink to give the quartz crystals this appearance. The quartz crystals are sharp and highly lustrous. In excellent condition, some incomplete spires. A beautiful piece.
Out of interest, there are photographs from Sidi Rahal in Morocco: The Northern Sahara and the Atlas Mountains (Part 1) .
