Smooth Finish, Impressive Results
This 3,000 grit diamond polishing compound completely exceeded my expectations. I’ve been using it on a variety of surfaces—marble, metal, and even a couple of resin pendants I cast recently—and the results are consistently excellent. The paste has a nice consistency that's easy to spread evenly, and it doesn’t dry out or gum up like some cheaper compounds I’ve tried before. What really impressed me is how high the concentration of diamond powder feels. It’s aggressive enough to make a noticeable difference quickly but still refined enough to give a smooth, glassy finish. I used just a dab on a felt wheel and brought a dull piece of silver back to a mirror shine. Same with a glass cabochon—it went from cloudy to crystal-clear in minutes. It’s also nice knowing it’s made in the USA. There’s a sense of quality control here that shows up in how reliable and consistent it is across different jobs. Whether I’m polishing jewelry or sharpening chisels, this compound gets the job done cleanly and quickly. A little goes a long way, so it's also a good value. I'll definitely be keeping a jar of this on hand in my shop.

High quality for honing the knives I keep sharp.
I use this on my leather strop that is the last step when I sharpen knives. It is just right for polishing the cutting edge and it lasts a long time before it needs to be replaced. Work much better than the stick rubbing compound I used to use.

Amazing product Amazing Results
This is an amazing product. I used it to restore the crystal on my father’s vintage Rolex and what a difference! The watch had one moderate scratch that I could catch with my fingernail and it completely took care of it.

Good for the price.
I’ve purchased this three times and have been generally satisfied. I use it on leather strops, and as a polishing compound for polishing scratched knife sides. It works well for my needs. I sense that the quantity of diamonds vs. carrier medium is not very high, but neither is the price, so you get what you pay for. I’m my case, I’m unwilling to pay more simply for a higher concentration of diamond dust, and for the price, this concentration of diamonds fulfills all my needs. I recommend it as such.

Great value and works beautifully
I have been using this product for about six weeks now on my strops. This stuff is long lasting and its impact is consistent on all my knives.

Refund please!!!!!
This product is useless and a waste of money. It does remove scratches even though I followed the directions to the letter. Buyer BEWARE and do not buy!!!!!

messy, builds up on blade.
It's a thick liquid, almost like a paste. I applied it to a strop on the smooth side. It just builds up on the blade edge. The plunger was bent, almost broken because the box got smashed in shipping. This would probably be okay on the suede side of the leather.

I think it works.
I think it does something? Can't really tell. Any time I've tried stropping a knife after sharpening in the past it's only made it get noticeably duller. This diamond compound seemed to make the bevel a little more shiny without dulling the knife, which is the best result I've ever gotten from stropping a knife after watching about 1000 videos on how to do it. Yaay me.

DÉÇU, j'imaginais mieux
Ja m'attendais tellement bien de cette façon de polir, peut-être mon besoin qui ne se prête pas à son usage, mais pour mon besoin, j'ai acheté 2 barres de métal enduite de poudre de diamant, une FINE et l'autre GROSSIÈRE et j'adore travailler avec ces outils et pour mon besoin, elles me dureront DES ANNÉES
