Third group

My daughter picked the top middle group for the third run.

100 grit grind --

Large quartzy stone was a pain in the rear. Several cavities in the dome. As it is, there are a number of cracks that reach the surface. Not sure how it will come out.

Pics where taken in my photo box from about six feet away and zoomed in. That seems the only way to get all the stones to have decent focus.

220 grit grind --

220 grit sanding --

Had to get a little creative to get a decent pic. Went with a shot of three and one of two.

360 grit sanding --

Moving slow... feeling under the weather.

600 grit sanding --

I like the color better on the pics without flash. But I can't seem to get a good sharp focus.

Another annoying thing. The pic editing software introduces artifacts. Like the round below has green splotches. I plan on getting another lamp with a 3000K light bulb. So that might be cleared up at that time.

The stone to the left of the large quartz has those flecks that the tripoli eats into. So I'll have an example of that. Speaking of that stone, it is interesting in that it is a mix of white and clear quartz with greenish black flecks. The round is also interesting in that it has green and blue material inside and a field (the brownish specks in the pic) that sparkles in the light.

Tripoli polishing --

You'll see in the closeup of the quartz with greenish, black flecks how the flecks have been chewed up. If I had persisted, it would only have gotten worse.

I wasn't able to get the sparkle of the round without some blurring. The light and dark areas of the round are reflections of the inside of my photo box.
