WHOAH! Hadley, where did you find that beauty? I love it!! (in my case, just as is!!)
JuBe and PtyMom -- It is at moissanitebridal.com. They are a sister company of Moissanite Fine Jewelry, which has some mixed reviews. I personally had a great experience with them a few years ago - super white stone, awesome customer service, all of it. But Less has caught them making unfair advertising claims, using incorrect photographs, etc. So proceed with caution.
Ginger -- I'm assuming that you already know the Tacori Crescent? If not, here's a photo of it.
