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.

I was skeptical about this diamond polish mainly because of the price. However, it was affordable enough that if it was junk, I didn't break the bank. I can safely say this product is not junk. I bought this to get a sharper shine on rocks that were previously polished by my tumbler. As you can see in the video, the contrast between the rock tumbler and the polish is night and day. In the video you'll see the polish from the tumbler (front side of the rock) and polishing further with the paste and a paper towel. (Back side of the rock) I bought the 8 tubes for $10 and it does NOT take much. I use a small dollop about 2x the size of a pin head and even that is a little much. Until I see a reason to invest in the "higher grade" stuff, this polish will more than suffice. Each tube is labeled with grade and grit (10, 7, 5, 3.5, 2.5, 1.5, 1, and .5 microns) Everything else is in Chinese so... 🤷‍♂️

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

Excellent deal for quality diamond lapping paste. One kit will last the average person for a LONG time ! The consistency of the paste is ideal for me.

Easy to use and great quality. Removed scratches from knife.

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

Very hard to tell the grit of each package because it's written in Mongolian.

This works perfect for what I needed it for plus I love in this kit all the different grit levels. Also the tubing that they come in makes it so that you don’t have to seal it off and it’s not a one time thing which I really appreciate. You get so many levels, and so many tubes if you’re just fixing stuff around the house, I can’t imagine ever going through even the amount that I bought.

Used for stropping newly sharpened blades and removing the final burr. Wide variety of grits. Seems to last on the strop

I found that this product, the 3 piece set(3.5, 1 & 0.5 microns) was so good at doing the final polishing, of some stones that I have bought, to a mirror finish, that I ordered the larger 8 piece set on the same day that the small set arrived, so that I could do scratch removal from some stones too….. While these cheaper pastes will do the job, you have to use a lot more, because they’re only about 5% to 10% diamond grit, so you will need to use more and spend longer polishing, while the more expensive versions are 50% diamond grit, which means that they will polish the item quicker, while you use a smaller amount…. The photos I have supplied, show the finish in areas that show the difference in before and after, which I got from JUST using the 3.5 micron paste, for less than a minute

The course grit is not abrasive enough to remove scratches. The fine grit is not delicate enough to bring glass back to a polished finish. I feel that the kit is, at best, incomplete so cannot rate highly.

Works ! The diamond paste works well for strops. Use very little, and itll sharpen up your knives quickly

Not tried these out yet as its still cold outside, but I’m sure they will do the job. I bought this for polishing stones ( some bought some found on the beach and some given to me as gifts). Can’t wait to try it out.
