"Royal Navy" is - like the name already suggests - a royal blue jelly loaded with tiny turquoise glitter particles.
I already did a jelly sandwich mani with it here (please scroll down to the 5th photo), but I think it deserves another post to show it in all its beauty.
Unfortunately, the glitter in this polish tends to sink to the bottom of the bottle, so you'd want to give it a whole lot of shaking before using it or even turn it on its head for a while.
This is what I did anyway to get the glitter to show up well. These pictures show 3 coats, but you can also get away with only two.
