Here's the follow-up to my post last week, regarding a couple of stones that I might take a look at. I nixed the second, and had him bring stone #1. This is how I previously described it...
1.09, H, VS2. GIA, ex/ex. 6.68x6.71x4.02 "AGS 0" HCA=.8
Depth %: 60
Table %: 57
Crown angle: 34.2
Pavillion angle: 40.7
Girdle: thin, faceted
Fluorescence: NONE
Key to symbols: cloud
Laser inscribed with "H&A" and GIA #
Here's a crappy copy of the cert and Sarin..
Looks pretty good on paper--but let's see how it performs under the lights.
Started out by examining it in a H&A viewer--looked very good. I was looking for major flaws--no gross differences in heart or arrow proportion, arrowheads not touching the bottom of the hearts, no splits in the middle of the hearts, etc etc. It passed, as far as I'm concerned.
Next up was the 'scope. There were a couple clouds that appeared to be beneath the star and UG facets, and one that was in a straight line and superficial. Almost looked like somebody took the stone and scraped it. It wasn't dust though--he dipped the stone before viewing. If I have any "concerns" about this stone, this is one of them, albeit minor.
Finally, I had to whip out the Idealscope. "Ever seen one of these," I asked. "Not in person, only on the heard about them..." He was curious to look for himself, but he was in no way put off by it (like I've heard some jewelers might be). I even snapped a few pics!
Bare with me on the quality, I'd not practiced any with my set-up (which consisted of a cough-syrup cup with a hole punched in it + Idealscope + Olympus C4000, set on super macro). I realize the stone may not be sitting perfectly level or the camera lens might not have been directly above the table.....it's the best I could do though. So I snapped several just in case, and here are the clearest...
I would put it at GOOD to VERY GOOD for light return on the IdealScope reference chart. Agree? Disagree? Comments on symmetry, as far as you can tell from the IS images (which may be a bit off kilter)? Overall, I was pleasantly surprised with this stone. Price = $6095.
Also am considering a couple 1.0x H VS2 H&A's at GOG (or others at this pricepoint if anyone has suggestions)....decisions decisions.
Sorry it got a bit long, but I wanted to be thorough. Thanks in advance.
