Here it is swatched in outdoor lighting - just the top part on the left, the "cupcake frosting"-looking part in the center, and the whole thing blended together on the right:

In short, I adore this highlighter. If it weren't so expensive, I'd buy a backup, but as it is, I will probably just use this somewhat sparingly so as to make it last. I purchased mine from my favorite Nordstrom sales associate, Sarah, who is the Guerlain counter manager at the Bellevue Nordstrom (store phone number 425-455-5800). If you need an excellent sales associate to help you with consultations or orders over the phone, via email, or in person, she is your girl!
What do you think? Are you eyeing the "cupcake highlighter" too?
