You need Pokemon with Theif or Covet, and Dive and surf. DO NOT LET THEM CARRY ITEMS.
If you go out to Lilycove, surf until you find a dark patch of water, dive, and find some seaweed. Swim around in it until you find a Clamperl. Use Thief or Covet on them to get the blue shards that will usually be attached to them. (Since you will be using this attack a lot, it is a good idea to have some Ethers or Leppa berries on hand.)
Once you get a blue shard, or two, or three, or however many you want, take the blue shard to the collector near Mossdeep and he'll exchange it for a Water Stone.
Another idea is to get someone to trade you one, either from Emerald, or FireRed/LeafGreen.
The best water Pokemon in sapphire would probably be Kyogre. -Hope I helped...:D
you can get it by going to route 119 at the tall grass
It can be used to evolve Pokémon.Jigglypuff into Wigglytuff,Skitty into Delcatty.
EEVEE evolves into VAPOREON by using a water stone
All Pokemon that evolve with the assistance of a Fire Stone: Vulpix Growlithe Eevee Pansear. So, no Pokemon in the third generation require a Fire Stone to evolve.
Yes, the water stone from Pokemon looks like Sapphire.

Yes in fact you can get dozens if you trade with firered or leafgreen because they can buy water stones all they need to do is trade you a Pokemon holding the water stone and when you get it just take the water stone from it!
Well there is only about 3 Pokemon that evolve with the sun stone and 2 in Pokemon sapphire gloom and sunkern which turn into bellossom and sunflora.

Lombre requires a water stone to evole and there are eevee's near the bike trail so you can catch and evole that. You can give your pickau a thunder stone if you want.
