Yes, I'm surprised it isn't talked about at all. It's an Asia and France boutique exclusive. It's part of their blanc de perle line that we don't get here, so you can imagine it's all about the glow. I'll try to take some pictures when I get home, but my balls are all white in tone with just barely a whisper of pink, blue, and white gold.. I wouldn't even consider them pastel shades, just shades of white and opal, I guess. I have tried several of the balls, and I have to say the 00 balls are quite different from the other ones. It leaves a pearly white sheen that can get too intense if I'm not careful, but I definitely notice that angelic glow.
Here are a few online reviews. I'd say mine show a bit more color variation, as I can see the slight blue balls, but you get the idea.

Edit: I forgot to mention, I call them my snow balls because they look like glistening snow. My husband gets a kick every time I talk about Meteorites because we just refer to them as the balls.
