Local quartize

We don't have much interesting local rock out here in the boonies of NH, so naturally I am excited when I do find something decent. This series of photos shows the result of my tumble of some rock that I found on our local road. The general consensus in the Rock Identification forum was that this was some sort of local quartize.

Here is what the rock looked like when I found it:


Here it is wet before I smashed it up:


After smashing with a small sledgehammer:


Notice the larger piece on the left, with the stripe between the yellow and red regions. I'll follow that rock through the process. Here it is going into the rough (60/90 SC in a Lortone 3#):


After one round of rough:


I ran it through 6 5-day rough cycles, then medium (120/200 SC), pre-polish (500 SC), another pre-polish (1000 AO), an AO polish, and then a quick burnish. It took just under 4 months all together. Here is how it finished out:




Keep in mind that we have no sun here in NH so these photos were taken under whatever lighting we happen to have indoors! :-)

Thanks for looking.
