If you look here...This is the set up your inventory should look like.

As you see you will need water and cosmic runes; as well as a chisel and, as well a ring mold(you can get from crafting store) and my d dagger is just a place holder.
1) To start you go to home, and go to the crafting store buy 11 sapphires(you should have about 1m before you do this)
2) Cut the 11 sapphires. Go to the mining tele.
3) Mine 11 gold ores. Then go to the Smithing tele.
4) Make the 11 gold ores into gold bars. Next use the gold bar on the furnace
5) Make all 11 rings. Then enchant the rings using the level 1 jew enchantment in your spell book.

Now to start out you could sell the rings to the junk store or if you have high level alchemy in you spell book unlocked.
Alch the rings for 450k ea.

The runes you will need is fire runes and nature runes.
Normally what i suggest is to save to 55 rings of recoil, and alch them all then for 21m profit.
The cost for all the runes and sapphires is around 2m when you make 55 rings so it is a 21m profit .
