The diversity of colors coming out of this mine is impressive!

After much research on these black spots you will see on the material I believe the most likely candidate for the species at hand would be a low grade of magnesiochromite. The color, hardness, luster and geology all match up.

Some shots of the magnesiochromite under the microscope.

Chrysotile & Tremolite:
Let’s address the white material shown on this Serpentine, this material is Chrysotile or white Asbestos, this is the most common form of asbestos. Chrysotile has been included with other forms of asbestos in being classified as a human carcinogen by the IARC and by the U.S. Department of Health and Human Services. These state that “Asbestos exposure is associated with parenchymal asbestosis, asbestos-related pleural abnormalities, peritoneal mesothelioma, and lung cancer, and it may be associated with cancer at some extra-thoracic sites”.

That said I feel like this material can still be safely collected, handled, cut, and polished if you use proper procedures but you can be the judge of that.

Ophiolite / Magnesite inclusions:

Here is the one piece I have that is a light green with light pink/red magnesite inclusions. One thing I found interesting about this specimen is that the serpentine didn’t really take much of a polish but the magnesite did.

The color seen below is potentially blue copper sulfate.
