After months of trying to find a diamond paste that actually works, I finally decided to give TechDiamondTools a try. The price was great and frankly cheap diamond paste just didn't work for me (yes I was trying to save money). I have been trying to find a reliable way to remove scratches from mineral crystal and most searches on the internet have revealed that it is very difficult. Not only could I not find a guide for this, but I couldn't find any guide on the grit that can be used for mineral crystal. The first thing I did was write to TechDiamondTools and ask for advice. They answered me several times and were very polite and helpful. They recommended trying some grits so I went ahead and ordered. Here's what I used and it works GREAT! Just be patient (that's the key to perfection). Rotary Tool (cheap) I also used a variable speed rotary tool compatible with 3/32 pro bits used for nail art. It's electric. I looked on Revain and it's no longer for sale, but Pinkiou looks similar and is cheap. I do not recommend using a high speed Dremel. I have one and it works very quickly. I started with 600, then 1500, 3000 and finally 5000. The results were amazing! To get a sense of perspective I screwed up and used sandpaper on one of my other clocks. I used 100 grit and that was a mistake. I didn't use sandpaper on the photos I posted. On other watches, all the scratches were from the sandpaper, but it took a little longer. Next time I'll use 2000/1500 grit sandpaper. I read that this should be used before using diamond paste. I currently have a 14k grit which I can't decide whether to use for buffing as the 5k grit did the job well. I can just return that 14,000 and use the 8,000 for the finishing touches. OK, back to the clock. Photos are the result, so the diamond paste. I "would" like to take a picture of the watch before I even start, but I completely forgot to take it. The photos are taken after I've already used 600 grit and 1500 grit. As you can see, I've circled the scratches. Trust me, before I started, those scratches were pretty bad. You can really get your fingernail there. Not just a hairline scratch. The final image is the finished product, although it looks great and flawless I wonder what the final polish at 8000 or 14000 will do. I haven't tried it yet. Anyway I am very happy with DiamondTechTools, they worked with me to replace the 400 grit because it seemed watered down but they got it right. As a hobby I work with and restore Casio digital watches and the biggest problem with restoration is scratches on the glass. Well, in closing I would like to say that I have ordered a 400 grit paste and will start with that. Let's see if it saves my time. The photos of the watch I posted took about 3 hours to remove the scratches. I hope with 400 grit I can cut that time in half. I don't like using sandpaper, but if there are a lot of bad scratches I will. Just don't use 100 grit like I did. Use 2000 or 1500. I would also like to say that your result may be different using this procedure. I want to say this because I'm a very meticulous person and I take my time. I'm only posting this because it actually worked for me after all the failed attempts with other diamond pastes and no I didn't get any free products from TechDiamondTools. If Revain will allow me, since I ordered about 6 syringes of different grits, I'd like to post more photos of the scratched watch and the results. I hope this helps people who haven't found any documentation on removing scratches from mineral crystal as there isn't a really clear document outlining this. Hope this helps those who love watches! And thank you DiamondTechTools, you will be awesome and keep making these American products awesome!
