Best Things in Beauty : Laura Mercier Shimmer Bloc in Mosaic

after so many raves and mentions in the beauty world i really wanted to try this highlighter. if it would be better than Dior Amber Diamond (which i have and really like), it must be worth a try. i'm talking about Laura Mercier Shimmer Bloc in Mosaic.
i bought it on ebay, i think i paid something around 30€ for it (shipping included), the shimmer blocs normally cost 38$.
it comes in a simple dark brown compact with a little mirror inside. Mosaic contains 4 different shimmery shades:

a taupy gold with rather apparent shimmer
a pinky peach with gold shimmer
a light cream with white shimmer
a pale gold with very fine gold pearl

mixed together, they give a shimmery peachy gold shade.
i like to use a very soft brush (A'Squirrel Pure Squirrel Angled Blush Brush) to apply it to the high points of my cheek bones, the brow bones and the cupid's bow. it applies evenly and blends out easily. it creates quite an intense highlight but very warm and soft, it's not too gold thanks to the peachy pink part in it. it's rather shimmery - more than i thought it would be and less fine than i wished. the shimmer is also more chunky than from the Dior Amber Diamond although similar in shade - there are just too many multicolour shimmers in it. i would appreciate it much more if all parts would have the same fine shimmer like the pale gold shade.
the first time after application it appears quite shimmery and also a bit chunky, but when i look into the mirror in the evening there is only a glowy sheen left and the chunks seemed to have melted into my skin or fallen off.
