I wish I had found a page like this when I started getting into carving greenstone. I have put this together as a way to share what I have learnt about how to do it with all that are interested. So this is all about how I go about sanding greenstone, or pounamu, or jade, or what ever you call it where you are from.
This post is all about showing sanding greenstone and how I go...

Finishing/Polishing
This is the most exciting part when the final beauty of the greentsone is revealed.
Here is what the greenstone pendant looks like.
I love the deep greens and black inclusions on this piece of greenstone.
You dont need to go through the grits like that.

Yea I have worked out some of this stuff, by no means all of it. This page does need updating. What do you mean by straight from 1200 is fine. I am also interested in what tools, techniques and materials are used to achieve a proper polish.
