_small.jpg) | Neat Copper from Bolivia that is part of the Academy of Natural Sciences of Philadelpha collection #19703. Number on the specimen and original Academy label. Copper on both sides of a brecciated matrix. Copper crystallized within the cracks in the brecciated matrix. The breccia is also held together by the Copper and could be separated by a little force to pull is apart to see what the Copper looks like in the center of the specimen but it also may be best to just keep as is. Interesting flattened Copper crystals. Ex Philadelphia Academy of Sciences |
