Diamond polishing compounds are special pastes that help make hard surfaces smooth and shiny. They contain tiny diamond particles—so small you can’t see them.

Where Are Diamond Polishing Compounds Used?

People use diamond polishing compounds on many things, such as:

Metals

Gemstones (like ruby, sapphire, and even diamonds)

Glass and ceramics

Tools and knives

Machine parts

When you rub the compound on a surface, the tiny diamond bits scrape away rough spots. Over time, the surface becomes smoother, brighter, and more polished.

What Material Is Used to Polish Diamonds?

It may sound surprising, but diamonds are polished with other diamonds.

Here’s why:

Diamonds are the hardest material, so nothing else can truly cut or polish them.

Jewelers use diamond dust or diamond polishing compounds to shape and shine a diamond.

Without diamond powder, a diamond would not get its famous sparkle and clear shine.

In simple words: Only a diamond can polish another diamond.
