Prehnite, Calcite, Copper and Chlorite in a Basalt matrix ,looks like it was an Agate at one time then replaced with later stage of minerals, collected at the N. Kearsarge Copper mine ,Houghton county, Michigan. Over all it is 2 7/16" x 3 1/4" x 1 1/4" and the amygdule is 1 5/8" x 1 1/8" x ? in the Basalt and it has been polished on the surface of the specimens.  Buyer pays all shipping by small flat rate box or international postal codes and extra insurance if requested and will combine items for cheaper shipping cost but let me send you an invoice for all your items 1st before you pay..  Thanks for looking and look at our store for other mineral specimens.
