Great for beginners

As someone new to stone polishing, this kit provided all the grits I needed to learn the process without buying separate bags for each stage.

Effective abrasive

Cuts through tough material quickly. Just remember to wear a mask if you are using it dry, as the dust is very fine.

Excellent consistency

I use this for grinding gemstones and the particle size seems very consistent. No large chunks that could scratch the surface unexpectedly.

Good value for the price

Works great for sandblasting small details. The only reason for 4 stars is that the packaging was slightly damaged upon arrival, but the product inside was fine.

High quality silicon carbide

Been using this brand for years. The 3000 grit gives a near-mirror finish when used correctly with a polishing wheel.

Perfect for jade polishing

The grit progression from 80 to 3000 is exactly what I needed for my lapidary work. The powder mixes well with water and leaves a smooth finish on hard stones.

A: Currently, this listing is for the 500g package. Larger bulk quantities may be available by contacting our sales department directly.
