What do jewelers use to polish diamonds?

I'm curious to know, what kind of tools or materials do professional jewelers typically use to achieve the dazzling shine and clarity that we often associate with polished diamonds? Are there specific compounds or techniques that are favored in the industry, or does it vary depending on the individual jeweler's preference and expertise? Additionally, I'm wondering if the polishing process has evolved significantly over time, and if so, how has it changed to better enhance the beauty and value of diamonds?
