I think this is what they call obsessive/compulsive disorder. I take meds for that....honest. Can you imagine how bling crazy I would be without it?? I am the same way. Whatever interests me today, I have to learn all I can about it and gather in all I can. Losing my ring to a thief has kinda cooled my jets on the bling though.
Milady, it's kind of a bad habit...it's like when I find the perfect shoes or cashmere sweater, the fit, the feel, I must get them in ALL color (lol)! I'm sure a few/many of our sisters are the same way, haha!!
ETA: Keep checking with HSN. I know that the JD emerald eternity that a few of us here have was sold out around the holidays. They stocked more afterwards. So keep checking. Good luck!
