The ongoing saga of the moonstones

A few updates.

I got the velvet and here's an example with my 40watt lamp in close-



I attempted a few pics with two lamps on the stone but multiple lights killed the blue flash. It was strange. I could see the blue but the camera didn't pick it up.

So I picked up a lamp and some 75watt bulbs.

Here's an example with the lamp in close --



And one in the photobox (sorry about the blurring) -



The photobox pic needs a much stronger lamp.

At this point I checked out terapeak and confirmed the main three price groups.

For the past 30days:
  • $0.01-1.99 -- generally no flash and near solid color
  • $2-5.00 -- a great deal of silk and some flash
  • $5-203.99 -- strong blue with the top prices going for clarity and size
That shows I'm in the top bracket for most of the parcel. In looking at the pics of the top stones it was clear that a strong lamp at a distance was used. So I tried a few pics with the lamp farther away from the stone. Here's one -



All of the above pics are of the same stone.

My current issue is that I need to repolish all of them.

As I said, when my head gets bad, detail work suffers. I noticed scratches on all of the stones in my pics. They really show up in bright light and magnification.

But such polishing is something I know I can do. So things aren't so bad... just moving much slower than I'd like.

=========

Ok, my head is feeling a bit better.

Going to do a few before pics and then repolish.

===============

First attempted to repolish on the 14K grit. Based on how slow it went I decided to try going back to the 600 grit.

The 600 grit gives a matte polish and the 1200 grit gives the beginning of the mirror polish. That matte polish hides scratches that the loupe doesn't show (or that I couldn't see). I'm thinking I should have only gone back to the 1200 grit. In working the stones tonight I'm starting to think I need a 800-900 grit step because the 600 to 1200 grit just moves too slow.
