1. What is grit?
Grit refers to a diamond particle size. The lower it is, the larger and coarser the particles are, and vice versa. For example, 200,000 Grit diamond powder is much finer than 400 Grit. Therefore, each grit is suitable for a specific application. That is why one should avoid accidentally mixing up different diamond powders or use the wrong powder by mistake. Hence, the best practice is to use new applicators (buffs, cloths, etc.) with each grit.
2. What is the difference between pastes with 10%, 25%, and 50% concentrations of diamond powder?
The higher the concentration is, the more diamond powder is in paste, and the less time and effort it will take to achieve the same result. If one needs to polish something small and (or) once, light concentration will work perfectly. For professional usage and (or) for large-scale work, we recommend taking higher concentration compounds.
3. Do you use polycrystalline diamond powders or monocrystalline?
Our diamond powders are polycrystalline.
4. What should I do if the compound is solid and impossible to eject?
It can happen due to the composition. If the paste is solid and does not come out as smoothly as you would like it to, put it in hot water or a microwave for 15 seconds. That will fix the problem.
5. How to thin the paste?
Mineral oil will help with that. You can also use it after you apply the compound to a surface, and it gets dry. Thus, it will last longer.
6. What is the best applicator to use with the paste?
The best options are a piece of wool fabric or leather. However, you could use any soft cloth. Wool and leather have better polishing qualities, though. Felt cloth is a good choice as well as felt bobs if you work with Dremel.
7. What are the general usage instructions?
- Apply a small amount on a piece of wool cloth or a polishing tool of choice.
- Spread the compound evenly.
- Buff the surface in a circular and (or) back-and-forth motion until you achieve the desired results.
- To avoid contamination, use separate and different pieces of cloth for each different grit size used.
8. Why don’t you use color additives to make it easier to distinguish different polishing pastes?
Firstly, we want our product to be safe for materials with high permeability. Secondly, that helps to maintain beneficial prices. To help buyers tell one tube from another, we ensure that each is correctly labeled. However, we understand that some may find it not enough. Therefore, here is a lifehack we learned from our customers: you can try using colored markers to mark syringes with different pastes. We hope it will work for you.

10. I polished and polished, but it’s still scratchy. Why is that?
To avoid this, one needs to understand that polishing is a multistep process. Start with polishing pastes or powders of lower grit and gradually work your way up. That job requires patience, but results will make you proud. Please read the answer to how to determine with what paste to start. We are rooting for you!
11. How can I determine what lapidary paste I need for my project?
- Is the material you work with hard or soft?
Use lower grits for hard materials. For soft materials, use higher polishing compounds with finer diamond powders. For instance, to polish shallow scratches on a ceramic tile, one will need the 4,000, 8,000, 50,000 polishing set. To polish epoxy resin, they will need 200,000 Grit polishing paste.
- What is the condition of the surface you want to treat?
Each grit removes some of the inconsistencies. Thus, the rougher the surface is, the lower the grit you will need. When the current compound is no longer effective, it is time to move on to the following grit number. Hence, gradually, one can eliminate unwanted scratches, unevenness and obtain a mesmerizing mirror shine.
Here is a little cheat list to help you understand what paste to start with:

- 100,000 Grit, 0 to 0,25 Microns – Polishing Paste, Final Polish

12. Can I use diamond compounds to strop my knife?
Yes. Please, read our short article about that.
13. Can your polishing compound remove a scratch from a smartphone screen?
A diamond compound can remove a scratch. However, one should remember about keeping the functionality of the screen and avoiding overkill. Do not try to use it to get rid of deep scratches. Please, be careful.
So, to treat a shallow scratch, we recommend the 4,000, 8,000, 50,000 set with a 25% concentration of diamond powder. It is ideally balanced for the need. Start with 4K and then work your way up to 50K.
1. Use tape to isolate the unscratched parts of your screen.
2. Apply the paste to a piece of cloth (wool cloth is perfect) and buff the scratch for about 1-2 minutes. Ideally, after 4k, the scratch will disappear. And every next grit will make the surface shinier. You can even try 4k and 8k.
3. Make sure you use a different piece of cloth with different grits.
14. Can I use your lapidary compound to polish gemstones?
Yes! It is a final touch your gem is waiting for. We have reviews from customers asserting it is the best compound to polish many stones such as opals, sapphires, agates, amethysts, and other quartzes.
15. Can it remove a scratch from a watch?
If the dial is glass or sapphire, then a diamond polishing compound can remove a scratch on your watch. However, if it is too deep, you should be prepared for some time-consuming work. First, you need to grind the scratch, soften its edges, and only after that start polishing.
16. Can I clean silver with diamond paste?
Yes. 50,000 Grit diamond polishing paste is suitable for silver cleaning and polishing.
