So yeah this was totally the kick in the heinie I needed to go get it reappraised. I will probably get it done and my larger OEC at the same time; IIRC I got them in 2007 & early 2008 respectively so they're both rather undervalued. I keep forgetting that diamond prices have gone up quite a bit since then.
Anyway, thanks for the moral support ; it was a truly unpleasant day all the way around.
