Astral Amethyst Moon has more of a translucent base with flecks of copper, fuchsia, and lavender sparkle throughout. It had larger, more textured sparkle compared to most of the brand's other Astral shades, and it seemed a little drier, too, which resulted in fallout during application and during wear. I will say that I was surprised that the fallout during application wasn't too bad--I expected way worse--but there was noticeable and definitely more fallout during the first few hours of wear than I've experienced previously with Astral shades.
The brand stated to use it with a dampened brush, which is how I tested longevity, but it was still a messier shade to use even with a dampened brush. It would not be ideal to use with a dry brush, and fingertips were so-so, as they improved coverage to more medium coverage but this shade really needed a tackier base to actually give it decent wear and minimize fallout. It's one thing to have fallout during application--just do your eyes first!--but fallout during wear can result in irritated eyes. Even with noticeable fallout, there was still a lot of product that remained in place on the eye when I took everything off after 10 hours of wear, though.
I tested the shade for longevity applied wet (with just water), wet with MAC Fix+, and over the brand's new IntensifEYES Artistry Wand. I found that the wear was similar with MAC Fix+ and the Artistry Wand with the wand giving slightly less initial fallout as it was a bit tackier. I did not feel like there was a big difference in opacity or how shiny/sparkly the end result was, so long as the product was used wet in some fashion (water or otherwise).
