Thanks to everyone who has helped me on this message board. After two months of searching, I may have finally found my ring. On CutNut's advice in a private email, I resisted the urge to buy quickly and waited for an OGI to get additional measurements on a stone I canvassed opinions on a few weeks ago on this message board. Here are the final numbers. Unfortunately, I don't have time to wait for a Sarin, so I'm hoping the OGI is good enough:
GIA certified
0.85 ct
VS2
G
Depth 61.7% (62% based on OGI)
Table 56.0% (56.6% based on OGI)
Crown angle 34.5 (based on OGI)
Pavillion angle 40.9 (based on OGI)
Pavillion depth 43.0% (based on OGI)
Polish-v.good
Symmetry-v.good
Thin to slightly thick girdle
Forgot to ask about OGI culet reading, but GIA cert says no culet
Medium blue fluorescence
Price: $3500 including a platinum setting with a small 0.1 ct baguette on each side
I ran the OGI numbers through the HCA and got a score of 1.3!
My only lingering concern is that I assumed a culet of zero for the HCA. Is that safe, since I have an OGI and no Sarin? Waiting for a sarin is out of the question now because I need the ring by next weekend! But I've heard that even the slightest culet can mess up HCA accuracy.
What do y'all think?
Special thanks to student who always shares his opinions with me on this stuff
I'm returning to the jeweler tomorrow or Sunday to get one last look and to make a final decision. He's holding it for me until then, and I'm pretty sure I'm going to scoop this one up.
