Tarte Amazonian Clay Blushers

Over the past year I have been lucky enough to try a fair amount of Tarte products. From the amazonian clay lipsticks and bronzers, to the liquid eyeshadows and illuminating serums. But theres one item that stands out amongst the plethora of pigmented, long lasting and beautifully packaged goodies. A product that causes many a beauty obsessive to get a little hot under the collar (and with good reason). Que the Amazonian Clay blushers. With Tarte finally launching in the UK (well QVC.uk) and the US Sephora now shipping around the world (the makeup gods have finally listened) I thought it was about time I gave my two cents on the highly sought after blushers.
Described as a long wearing, supremely soft blush, infused with amazonian clay, harvested from the banks of the amazonian river and naturally basked by the sun, its fair to say that these blushers are really quite special. Seriously pigmented, yet still buildable enough to create both a subtle and shocking finish. Long lasting, cruelty free, encased within shade appropriate packaging embossed with the amazonian river and available in a range of shades and finishes suitable for every skin tone, whats not to love?! 
I currently have four shades, although there's always room for more right? 1 full size in Tipsy, a beautiful matte coral and three miniatures from the Tarte Fantastic Foursome Holiday set (my friend has the fourth) in Fantastic, a soft Fuchsia. Magic, a pink coral and Stellar, a shimmering nude that also doubles as a bronzer. Although a different range of finishes, all four are seriously pigmented and very smooth, making them seriously worth the £20+ price tag.  What are your thoughts on the Tarte Amazonian Clay Blushers?
