After 4 weeks in the rotary, 2 in 60/90 and 2 in 120/220, I dumped the labradorite into the vibe. Added tons of ceramic and rubber fillers, and added some aventurine and some softer odds and ends that were laying around - all of which is to be filler for the labs. Ran it in the vibe with 500 AO for 36 hours, dumped it, cleaned it, then 3 hours in the vibe with borax. Then I took these pics. First, the whole batch: The green aventurine: The peach aventurine: The odds-n-ends: And, finally, the labradorite: One up close to see the flash and the impact scars: After drying out some, I see that a lot (most) of the aventurine has impact scars, and most of it needs to be broken and started over by itself if I'm ever to really use it for anything besides filler. The labs do have a few scars, but not bad. Almost all of them show some or a lot of flash. Trying to get them to sit in a position where I could take a picture of the flash was a no-win situation, so I gave up. I do wish I had a bunch more ceramic fillers to replace the non-labradorites in the batch, but I don't, so this will have to do for now. (Or, alternatively, a LOT more labradorite that is past the 120/220 stage!) So now the batch is back in the vibe with 1000 AO. I'll check it every few hours to make sure it's wet enough and turning well, but it will run for at least 24 hours straight before I take anything out for examination. Thanks for any input, Tom

OK, since you asked, and mind you this is just my opinion based on how I like my tumbles, but Id take all the stones back to coarse grind and go for much rounder contours before I moved them on. Rounder shapes polish easier and tend not to have the edges where impact scaring mostly occurs. Some of your filler looks like Mariposite which will undercut in most tumbles too. IMHO, no use even moving pitted or scared stones along until all the problem areas have a smooth silky finish from the grind stages. If you do, the net result will be unevenly polished pieces that leave a lot to be desired.....Mel

I have to agree with Mel. Save your money on the 1000 until you've run another cycle (or more) in coarse. You might also load your vibe even more to help reduce the impact problems.

Thanks, Mel and Chuck - I will do just that. However, I have some more labradorite rough on order, and I'll probably wait until I have enough to make a load of only labradorite. Right? I also have a bunch more ceramic filler ordered, so I won't have to use other stones as filler. While I'm waiting, I'll get out the ol' WF and cut up the aventurine pieces that need it and take off some of the sharp edges and points, and maybe I'll make a full vibe load of that. Tom

Sounds like a plan. You'll probably end up with labradorite in different stages of progression, some ready to move on and some not. You won't harm anything by continuing to tumble those that are ready to move on, except they'll get smaller. Of course, you can always use filler in the rough grind.

I am so glad that I am not the only one having issues with Spectralite/Labradorite.
It is now set aside for its own batch in the rotary with lots of plastic pellets.
One question though .... isn't 2 weeks in 60/90 and 2 weeks in 120/220 too much for the Spectralite/Labradorite?
As always ... Julie
