I recently opened a pocket of dolomite crystals in Norway, Mi. and they had red edges along many of the crystals.
Considering where they come from, I'm assuming the red coloring is due to iron. This is the only pocket of dolomite
crystals that I EVER found up here with this color zoning. The matrix is a jasperoid material. Approx. size: 49x36x25
Weight: 30.8 grams

This is a rather large specimen from Felch, Mi. It has crystal-lined vugs on every surface of the solid dolomite
matrix, most of which contain only tan dolomite crystals. There is one vug with white drusy quartz and two more
have pyrite in them. Scattered about the piece is a sparkly chromium mica. I had a hard time getting a good picture
of the whole piece because of it's size, but would be happy to take more and send them to anyone interested in this fantastic
piece! Approx. size: 142x120x68 Weight: 915 grams.
