Kay, that looks quite beautiful!
I personally never put anything on my nails.. people always ask me if I did put anyways. Calcium is the key

There are some vitamins and other things you get from foods which completely change the appearance of your nails, hairs..
My nails are naturally shiny pink, one of the reasons is due to high calcium. I get asked a lot if I have anything on (sometimes about lips too, but I have no idea what might cause that.. probably also good diet).
I helped mom improve her diets and vitamins deficiency, things seem so much better for her too.
But I still think the photo Kay posted is just beautiful work on the nails, probably much beyond you can get with naturally. Makes me want to consider messing around with stuff too

Also makes me wonder, Kay, are you using some skin regime? it looks smooth and bright with a bit of shine. Or is it just healthy skin and maybe some camera/light smoothing it a bit more?
