I don't know what the directions are for your machine but for my vibe you still need the 1000 and the polish. From what I can see the pictures show a matt finish and just need the next two steps. Good luck!

I’ve ran 60-90 from 7 to 21 days, 120-220 for 10 days, and 500 for seven. Some members are showing some shine after 7 days in 500, that’s why I’m questioning where I am with the tumble.

You are good and on the right track. Too add, I have never had a shine starting on most of my jasper until polish stage

I have never had any kind of shine after 500 grit. Under a 10X loupe you can see that the surface of the stones are much smoother after 500 grit than after 60-90 and 120/220, but the shine only comes in the polish stage.
One thing though, I'm curious if you are really running 500 AO? My 500F grit is all silicon carbide. Silicon carbide has very sharp edges so removes the rough surface spots of the previous stage quite quickly (1 week). Aluminum oxide occurs as fairly rounded particles, so while they are close in Mohs hardness to silicon carbide (9.0 vs 9.3), the rounded shape of AlO makes it much less efficient at removing the coarser scratches from the previous stage.

Thanks for the info. It is 500 AO from The Rock Shed.

I ended up culling a few things out and don't have enough material to fill my barrel. Going to get some more material ready to go to polish, need to go through 120-220 and 500. Patience, Jim, patience.

I tumble those desert jaspers from the rockshed all the time and they usually come out great.They have become my favorite rock to tumble If your barrel is not filled and your anxious just fill the void with ceramics I would run what you have in soap /borax for a few hours or a day and then polish them They will come out great
Good Luck Bill

rollingstone is a master rotary tumbler, so listen to him. I mostly use a Lot-O vibratory tumbler, so I am not a rotary expert. When I have tumbled rocks in a rotary, I have not had a shine after 500 AO (from the Rock Shed). Those same rocks came out pretty shiny after going though polish. On the other hand, when I use my Lot-O with AO 500, the rocks are quite shiny after two days. Be sure that the rocks you’re looking at were done in the same type of tumbler before making comparisons.

You've already gotten great guidance. The only thing I would offer is that perhaps those shiny rocks you're seeing after 500 is because they may be wet in addition to what Rob Jugglerguy mentioned about the Loto.
