MAC Mineralize blushes are part of the regular line up and are available online, at counters and shops. They're £19 each and you get 3.5g of product. That's quite a bit less than their pressed blushes (you get 6g in those).
Gentle is described as a raspberry with gold pearl on the website. I don't quite agree there. I don't think there's quite enough red in this to be described as raspberry, but it is a fairly deep pink. It has quite a bit of shimmer and a bit of coppery glimmer. The texture of these does feel a little different to their pressed blushes. These feel a little drier but still nice and smooth.
This is pretty pigmented, I find baked products can be a little less pigmented than pressed blushers (but deeper colours tend to show better) but this doesn't suffer from a lack of pigmentation! I find this blends very easily into the skin and it's quite difficult to over apply this. I don't find this quite as long lasting as the pressed blushers, at around the 8 hour point it's starting to fade.
