12pcs 5 Gram Diamond Lapping Paste Polishing Compound for Fine to Final Polishing, Grits 1000# 10000# 0.5-40 Micron

I bought these to use them on coins I collect for fun, (not valuable), and they work great. One of them came without a cap, but they do what they say they will do. This isn't a scientific or detailed review, just that I have used the polishes on tarnished/crappy coins and they help clean them up easily. I also used one of them with a dremel to do a little fine polishing, again, great. Very inexpensive, easy to use. They come in poor packaging but mine survived fine. I like the coloring (likely food coloring), helps you remember what you have just used, and you can see the polish darken as it removes tarnish, etc.

Perfect

It's cheap and one of the syringes leaked during transit but it put a mirror finish on S130V steel

Just remember this is in microns, not grit. As advertised and was able to polish an old pocket watch glass to perfection!!

Worked very well removing the scratches and polishing my Garmin. I was skeptical considering the low price but wanted to give it a try. I wanted the 3 different grits and didn't want to spend over $30 with the techdiamondtools compounds to get all 3. This is a review for the 3pc polish 3.5,1, & .5 micron. I highly recommend the use of a Dremel. As you can see in the pics it removed all the light scratches. My old watch has been given new life. I'm very happy w the results. This is not a paid review or a free product review. All reviews are my honest opinion.

CHEAP. In all aspects. It does work, but it is very time consuming. This must have less than 5% concentration of Diamond dust. The pink, 8000 grit has stained numerous pieces of chalcedony. See attached pic. The pink spots were white. Good fire a beginner maybe. The staining is why I rated 2 stars. Would give it 4 as it's good learning learning or those on a budget.

Low diamond concentration ,good for polishing purposes not serious metal removal

I used this to hand polish some firearm parts and was quite happy with it. It cuts fairly fast and finishes as expected. Might be a little redundant with so many different grits so close to each other but that's fine as you can just use the next higher or lower grit if you run out of one. I would like more of the finest grits as I used them the most.
