When it comes to achieving a flawless, mirror-like finish on metals, gemstones, glass, or ceramics, diamond polishing compound stands out as the top choice. Whether you are polishing jewelry, sharpening knives, restoring watches, or completing industrial projects, using the right polishing medium can make all the difference.
In this guide, we’ll explore the top 5 benefits of using diamond polishing compound compared to other abrasives — and why it’s the ultimate solution for both professionals and hobbyists.
1. Superior Hardness for Faster and Deeper Polishing
Diamonds are the hardest known material (10 on the Mohs hardness scale), which means diamond polishing compounds can cut, grind, and polish materials much faster and more efficiently than traditional abrasives like aluminum oxide or cerium oxide.
- Faster scratch removal
- Deeper, more refined polishing results
Fact: A diamond can polish even the toughest surfaces, such as sapphire, tungsten carbide, and hardened steel, where other abrasives fail.
2. Longer Lasting Performance
Unlike softer abrasives that break down quickly under pressure, diamond particles maintain their shape and cutting power longer.
This translates into:
- Less frequent reapplication
- Lower material costs over time
- Consistent, high-quality results across multiple projects
Tip: With TechDiamondTools’ oil-based diamond compound, you also get extended shelf life and protection against drying out.
3. Versatility Across Different Materials and Applications
Whether you’re working manually with a leather strop or using machine polishers, diamond polishing compounds adapt perfectly. They can polish a wide range of surfaces including:
- Metals (steel, aluminum, brass)
- Glass and watch crystals
- Ceramics and gemstones
- Epoxy resin and plastic
4. Cleaner Polishing with Oil-Based Formulas
Oil-based diamond polishing compounds, like those offered by TechDiamondTools, provide a much cleaner polishing process:
- Less airborne dust compared to powder abrasives
- Smoother application on surfaces
- Reduced risk of contamination, especially on porous materials
Our compounds are free from artificial colorants, making them safer for high-permeability surfaces such as glass, sapphire, and stainless steel.
5. Greater Control and Precision
Diamond compounds offer better control over the polishing process because of their:
- Consistent particle size distribution
- High concentration of diamond content (up to 25%)
- Ability to choose the right grit for every stage (rough lapping to mirror finish)
For example, TechDiamondTools offers grits ranging from 50,000 grit (for final polish) to 450 grit (for rough lapping) — giving you professional results at every stage.
