High quality diamond paste at an affordable price. The quality has proven to be acceptable in my comparison tests with top quality diamond pastes on the market (the tests were performed on watch mineral glasses).
For best results, polishing should start with lowest grit number (e.g., 400) and end with the highest (e.g., 60000) -- you can choose the grits you need and request for combined postage.
The particle size is 10-20um (W10-W20).
