Description

This calcite comes from a more unusual locality near the tip of the South Island. I am not 100% certain that this locality is correct, however I have no reason to doubt the label accompanying the specimen. There is a limestone quarry in the vacinity and this may be a possible source.

The specimen forms acute tapering white crystals around a dark coloured earthy matrix. No damage.
