Please help identify this rock. Serpentine ?

It weighs 12.7 pounds, and is fairly soft (can be scratched by metal object).

Sorry that I can't help with ID but it is a beautiful rock!

Don't appear to have the habit of serpentine, maybe someone who is more knowledgeable will weigh in on your question.

It looks like it could be Antigorite Serpentine and Kaolinite. Or possibly Picrolite with talc. How soft is the white portion?
