White platy Calcite. This is a variety of Calcite called "argentine", which alludes to its silvery appearance allegedly seen in the miner's eye. Sorry, I don't see it either. The Calcite is composed of platy, undulating, crystals giving it a look of silver. The specimen originated from the Philadelphia collection break-up several years ago (note old ink label in the prov. tab). You will also see an example of "argentine" from Cornwall on Mindat. Even the English were fooled. Historic significance.

This is a nice group of divergent columnar Calcite crystals with cavernous centers filled with tiny rhombic crystals as is the outer "prism" faces. This occurence is noted in the Dal'negorsk book by the Mineralogic Almanac volume 4, 2001 titled "DALNEGORSK". A photo of this same occurence and habit is shown on page 47, in which it is described as "case-like". It quite fascinating and actually sits unaided straight up.
