These two features make sand a good medium for blasting a surface.
By far, the best combination for polishing garnets and tourmalines is a phenolic lap and an aluminium oxide (Al 2 O 3) 've often used and recommended tin laps and oxide polishes for these stones, but tin laps are just too expensive.

Completion designs today utilize either naturally occurring crystalline silica sand or an engineered proppant material including ceramic. Because of their use in superhigh pressure environments (often 10,000 feet below the surface), proppants are highly crushresistant to hold fractures open for as long as possible, helping to increases the productivity of the well.
