Will those stones EVER be finished?

Ok, so last Saturday, you saw these stones after their second round of tumbling:

Now a mere three days later, after tumbling with a pre-polish, here they are:

I'll admit, they look a little rough, but the light wasn't so good.  And believe it or not, both of these pictures were taken with my cellphone.  I need a new camera.

But, anyway, one more week, and they should be done, all nice and polished up.  At the very least I'll also have some polished amethyst.  The tumbler has to have both barrels full to stay in balance.  We'll see what they look like next Tuesday.
