Opinions on Tec Crystal Grout

I am finishing up my shower build and to finish off our white 6x6 wall tiles, i want to use Design FX^® Tile Grout in Crystal to add a flare to the shower. The rest of my bathroom is pretty eclectic so we toned down the shower but i love the idea of glitter grout. Does anyone have experience with this? i can find pictures anywhere other than glass tiles and id love to see how it looks next to white porcelain tiles before i buy it.
