Diamond Paste

The diamond grinding paste is mixed with a water soluble oil and comes in an easy to apply syringe so paste is ready to use and is easy to apply.

Use on glass, metals, ceramic and mineral surfaces to give a superfine, mirror finish to your surfaces or to sharpen the edges of your tools. Many scientists use the 0.25 micron to give a microscopic ultra smooth finish to their work.

Ideal for removing scratches on watch glass, glass or gemstones. Try starting with 3 micron (green), then 1 micron (blue) and so on until the desired finish is achieved.

How to use our Diamond Polishing Paste

Most diamond paste grinding and polishing is done progressively, starting with the coarser grade, 6 microns, and then finishing with the 1 or quarter micron grade. If the work you are polishing is already of a reasonable finish then you can often skip the coarser grades and start with the 3 or 1 micron. To apply the paste you can either use a felt polishing bob on a rotary tool,a piece of leather or wood or if polishing a pivot then apply the paste directly and then use a wooden peg to grind with. Alternatively apply to a soft wheel using a canvas belt, one belt for each grade. There are so many ways to apply the paste it seems that everyone has their own method, I have even heard of one horologist using some old camera film!


0.25 micron is the finest grade progressing upwards to 90 micron the coarsest. All are supplied in a 5g syringe
