Well... poop! I was looking for garnet a couple of years ago. I could have sworn that tractor supply stocked 20 mesh sub angular alluvial garnet but I cannot find it at all anymore. I was going to pick some up next time I crossed into the states. It is used water cutting, sand blasting, and water filters.with just a quick search, all I could find in Garnet sand was sand blasting media, with pretty "sharp" edges
I have found that some blasting media, Silca Sand in particular, is not as angular as you would think. For example I did a little bit on the Silca Sand here: https://www.fishforums.net/threads/using-silica-sand-as-substrate.486199/. I am no longer using it but that is more due to me tearing down the fishtank and moving all the fish to my normal living area and out of the basement.
