Got a bunch of Labradorite & found rainbows!!! and more!

So I picked up about 8 pounds of Labradorite for tumbling.  It was pretty cheap, and I love iridescence, so I thought I would give it a try in the tumbler...  Smallest pieces are about 1/2 x 3/4 to 1 x 1 1/4 from a batch I bought on amazon.  ALL of them have lots of iridescence when I put them in a Mason jar with water, but mostly blue, one piece had some yellow, gold/orange, red. 

I also bought 5lbs from the Rock Shed, larger pieces, up to about 2" x 3"  Two of these pieces have some full rainbow going on, but only in small areas...



Not much to this piece, maybe 1/4" wide x 1 1/4" long & angle has to be pretty precise to see it, but it's almost full rainbow there, missing is indigo & deep purple.

Then there's this piece: 


A little over 1/2" wide by my thumb, and about an inch long.  It does have the full rainbow, and even blue so dark it looks black.




Also found a piece with a nice purple field!




NOT Labradorite.... but I also bought a piece of "Sapphire" that was HEAVILY dyed a deep blue.  I'm relatively certain it is Sapphire, just a clear one.  It has been in the tumbler for 2 weeks and has not lost any measurable weight, but my scale only does whole grams...   The blue dye was hiding this:

 With the light at just the right angle the color shifts to a nice purple.

Checking the progress on the Labradorite, and found this one:


Some nice yellow / gold / orange in there 


And also a pic of that 'sapphire' before I put it in the tumbler.  This was after soaking in water overnight to remove as much of the blue dye as I could!



I wasn't sure what to make of it at that point

Those look like they have some nice potential!
