This is a Brand NEW FIND!! that features a section of an over a meter diameter pocket that was in this case trapped within a strange material a once liquid dolomitic limestone called carbonatite. The crystals seen here weathering out of the stone are called tremolites. It is very big but also fairly fragile so it would have to be shipped alone in a caccon of soft packing material. It measures 13″ by 9″‘ by 5.5″ and weighs in at over twenty five pounds and a half. So shipping will have to be quoted (Aprox $35.00) for most Locals within North America. This is a Real Museum grade find thanks for your time.
Also not that reasonable offers will be considered
