Description

This is a piece of coarsely crystallized zone of an exotic metal ore of an element know as niobium and other rare earth eleements.  One of  the main ore sources is the octehedral pyrochlore (Na,Ca)2Nb2O6(OH,F) and some columbite too, in a carbonaceous igneous rock called a carbonatite (that’s right a liquid limestone of sorts!), from Chicutami Quebec.
It measures 4.5″ by 4″ by 3.5″, and weighs in at four pounds three ounces, so the Shipping should be $20.00 for most locals within North America.
