yes, it is lily25. They sometimes try to divide them into champagne, cognac, and chocolate. I have a wide range of colors that will make me happy, so I just say brown when I'm chatting with jewelers.
I just got off the phone, and my first choice jeweler has a 6+ carat emerald cut in the estimated price range. I really wanted something with lots of facets and fire though to balance out the dark color. I guess I feel like an emerald cut brown diamond will end up looking like a citrine or smoky topaz, and that's not what I want for a solitaire. But they said there's still lots out there in my preferred size/price range. So yay! And thank you guys for the comments. Please keep 'em coming. This is going to be a several month process for me, I think.
