TechDiamondTools Diamond Polishing Compound Polishing Paste USA Made 2,000 Grit 4-8 Microns for Marble Glass Metal Rock Jewelry Resin Silver Chrome Gemstone with High Concentration of Diamond Powder

After months of trying to find a true working diamond paste, I finally decided to try TechDiamondTools. The pricing was great and quite frankly the cheap diamond paste was just not working for me (yeah...i tried to go cheap). I've been trying to find a reliable way to get scratches out of mineral glass and most internet searches claimed it was very difficult. Not only could I not find a guide to do this, but couldn't find a grit guide to use for mineral glass. The first thing I did was message the TechDiamondTools and asked for guidance. They replied to me several times and have been very courteous and helpful. They recommended several grits to try, so I went ahead and ordered. Here is what I used, and it works GREAT! Just be patient (this is the key to perfection). Rotary Tool (Cheap) I also used an adjustable speed control rotary tool with 3/32 pro bits compatible that is used for nail manicures. It's electric. I did a search on Amazon and the no longer sell it, but Pinkiou looks similar and it's cheap. I don't recommend using a high speed Dremel. I have one and it goes way to fast. I started with 600, then 1,500, 3,000, and finally 5,000 grit. The results were amazing! Now to keep things in perspective, I did mess up and used sandpaper on one of my other watches. Used 100 grit and that was a mistake. The pictures I posted, I didn't use sandpaper. On the other watch, it did get all the scratches the sandpaper made, however it took a bit more of time. Next time I'm using 2,000/1,500 grit sandpaper. I've read that's what should be used before using diamond paste. I currently have a 14,000 grit that I can't decide whether to use for polishing since the 5,000 did a superb job. I may just return that 14,000 and use the 8,000 for final polishing. Okay, back to the watch. the pictures are the result so the diamond paste. I "wish" that I had a picture of the watch before I even started, but I totally forgot to take some. The pictures are after I had already gone through using the 600 grit and the 1500 grit. As you can see the scratches I circled. Trust me before I started, these scratches were pretty bad. You could actually catch you fingernail on it. Not just a hairline scratch either. The final picture is the finished product, although it looks superb and flawless, I wonder what a final polish with 8,000 or 14,000 would do. I haven't tried that yet. Anyway, I am very pleased with DiamondTechTools, they actually worked with me to replace the 400 grit because it seemed watered down, but they made it right. As a hobby I work on Casio's digital watches and refurbish them, and the biggest problem with refurbishing is the scratches on the glass. Well to end this, I'd like to say I did order the 400 grit paste and will start with that to see if it cuts back on my time. The pictures of the watch I posted took me about 3 hours to get the scratches out, I'm hoping with 400 grit, I'm able to cut that time in half. I don't like to used sand paper, but I will if there are a lot of bad scratches, then I will. Just don't use 100 grit like I did. Use 2,000 or 1,500. I'd also like to say, if you use this process, your result may vary. I want to say that because I'm a very meticulous person and I take my time. I'm only putting this out because this actually worked for me after all failed attempts with other diamond paste, and no I didn't get any free products from TechDiamondTools. If Amazon lets me, since I ordered like 6 syringes of different grits, I want to post more pictures of scratched up watches and the results. Hope this helps folks out there that have not found any documents on getting scratches out of mineral glass, because there really isn't any clear document that outline this. Hope this help those watch enthusiast out there!! And thank you DiamondTechTools, ya'll are awesome and keep making those American Products GREAT!!!

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.

Fantastic product that delivers great results. You have to be patient and willing to go through a process, but it’s well worth it. I did several applications of the diamond paste. First two applications, I took small dabs of past on my finger, and pushed them into the scratches, filling them in and then taking a wet q-tip to gently, with slight pressure, massaging the paste around in a circular motion. After those first two applications, I already noticed the scratches becoming more dull and unnoticeable. The last three applications, I cut a plush microfiber cloth into 1” x 1” squares and applied the paste directly onto them. I dampened them with a bit of water and and again massaged the paste around the watch face, with slightly more pressure and faster motion. Conclusion: Deep scratches gone and a restored watch face. I think it looks better than it did before. Thank you.

Works well, polished 14c with ease. Came out of the tube a little too easy so be careful it's easy to waste.

After four years, many, many dollars spent on top of the line pocket knives and sharpening implements, and many, many hours of practice sharpening by hand, I'm confident enough in my skills to boast that I'll take the Pepsi challenge with the edge I can get free-hand against anything a wicked edge/lansky/spyderco sharpmaker/etc. can do with contraptions that fix the angle. At the moment, I use only diamond stones, strops, and a couple very hard natural finishing stones--no water stones in my toolkit yet, which are, I'm told, both the most effective but also most demanding to use correctly. I'll begin working with them soon enough, but there's only so much time and money available to invest in this little hobby. As for my take on this diamond paste, well...I definitely did not expect the results I got. Or perhaps more accurately, I didn't expect the results to have the effects that they did. I used the 14K grit, 25% concentration diamond paste on a number of blade bevels following, firstly, a few passes on an 8000 grit, extra-extra fine DMT stone, or surgical black novoculite stone (occasionally I find a blade will finish better with one or the other for some reason), then a leather strop impregnated with white compound, and finally, on a second leather strop loaded with green compound. The diamond paste itself I smeared on a low-knap leather strop. I'm not yet neurotic enough to check my work under a microscope, but to the naked eye, the 14K grit paste gave the blade edge a nice mirror shine, as you can see on one of my Rowdy Hi-Techs in the pics. I love the look of a mirrored edge (or entire blade for that matter; I wish more knifemakers would offer them), but I was definitely surprised by how much sharper the mirrored edges were. There's probably a metallurgist or materials engineer thinking, "no kidding, genius. A finer grit = smoother finish = sharper blade," but I really thought the benefits gained by the jump from maybe 10K grit with the green stropping compound to 14K grit would be functionally cosmetic. I was very wrong: in short, when properly utilized, this stuff makes your knives sharper, and the difference is significant enough that it can be felt with just the standard three-finger test grip on the cutting edge. This is my first purchase of a diamond-infused compound, so naturally I read through the majority of the (at time of writing) 200+ reviews before buying, and though overall positive, there were complaints about the consistency of the paste being too difficult to work with for stropping knives, the concentration being perceived as lower than advertised, etc. I realize that different product batches might vary in characteristics, and that the reviews for all the individual products with variable grit levels and diamond concentrations are conglomerated, but I still find myself at something of a loss to understand the complaints. If this product were priced at 50 to 125% higher like similar products, I might rate it as "good". But considering the much lower price along with the performance, I couldn't be happier with it, and will be purchasing finer grits immediately to see if maybe I can't get a blade edge to glow.

As described, I was happy with this.

I gave this three stars simply because it is made in America. But it just didn't work on my scratch up phone screen. My friend had this and shared some with me. I tried it to no luck. I thought maybe if I bought some and used more then it may work. It didn't.

I’ve used several brands of Diamond paste products for my knives, chisels, and plane blades! This product costs less than some, but gives good service for the price! A little dab on your strop, rub it in with your fingers, then go to town honing your blade! I don’t see much difference in the sub-micron grades. Anything from 5-.05 will give you a mirror like surface that will be sharp!
