Here’s an interesting new item, a Copper Pipe Amygdule from the Copper Falls Mine in Keweenaw County upper Michigan Peninsula. It measures 3 3/8″ x 1 5/8″. These extra nice specimens are getting rare and generally no longer available to the public. Very nice.

Pipe amygdules form in the last stages of lava cooling as gasses escape or are trapped within the flow. In this case, the lava was stationary and the gas bubble basically vertical. Following cooling, copper-rich solutions filled the void and the pipe amygdule was the result.
