I use these and reckon they are fantastic, they have plastic rubber type pads over the knuckes so they don't get smashed around and wear out or get holes in them, the gloves themselves do quite well in water and don't get saggy at all when wet, unlike rubber gloves or similar which turn into balloons when they fill up with water these will work happily submerged all day, they are reasonably tough and hard wearing but still give you reasonable feel in the ends of the fingers.
I found I was having the same problems as you with busting up my nails and the ends of my fingers, in addition to that, taking the bark off my knuckles quite regularly when scraping out narrow crevices, waterlogged skin is no match for rough stone!
At $20 they aren't too expensive to replace when they do eventually wear out.
