Review on USA Made Diamond Polishing Compound Kit - 5 Grits (1200, 1500, 2000, 3000 & 4000) For Marble Glass Metal Rock Jewelry Resin Silver With High Concentration Of Diamond Powder. by Robert Layne

this is my first time using this. so i was unsure as how to. but came up with something that works for me. thus, this is great stuff! had some rocks that had tumbled for 14+ days. they yet didnt get the luster i wanted. took the same stone, put some pates to this tip. and man! in seconds you could see the shine! and that was with this 14,000 grit. i cant want to see how the 50,00 and 200,000 do! so yeah i am very pleased. .
