Note: Diamond Polishing Paste is a paste with ultra-fine diamond particles mixed into it. It is designed to be used as a secondary ultra-fine polish after a more general polish has been applied, such as our Astro Tech polish: 

Diamond polish can also be very helpful in polishing materials that would otherwise have a Mohs hardness level too high for other polishes to affect.  We recommend using it if you are an extreme perfectionist about your ring finishes, or if you are looking for an effective method to polish tungsten, ceramic, or any other hard material.
