This is such a unique shade, a deep sparkly purple, it's not shimmer, but it's not glitter either.. it's so hard to explain. It really has a beautiful sparkle to it, not the most pigmented eyeshadow ever but if you apply it over an eyeshadow base (I like to use urban decay's delinquent ) it really pops and makes a delicious sparkly violet-grape shade. It glides on pretty easy, has a nice buttery texture to it, although it does need some building up, other than that it blends easily and it's very easy to work with :)
I recently purchased this eyeshadow in my local Sephora store the other day, and I absolutely love it! It was my first Make Up For Ever purchase and I've got to say, I was pleasantly surprised! The color payoff and pigmentation is great. I wore this on New Years Eve, and from 6pm to 4am I saw little to no fading of color, and it held up wonderfully (I did wear primer on my eyes). This particular shade is great for those will green or hazel eyes (though I'm sure it would look great on other eye colors as well!), and I got compliments all day. I'm very impressed with this eye shadow and will definitely be purchasing other shades!
I don't really know why this is a dollar more than the regular shadows, but the sparkle in this shadow is amazing. I can see why they call it "diamond". Using this while wet is important, especially for the blue. Swatched dry, it looks gray, but making your brush wet makes the color much more iridescent and match the swatch on the website. Little fallout and great staying power.
