Crafting is a useful skill. You can use it to create jewelry, and even earn money!
It is a fairly simple skill to do and succeed in.
To start off...
25 GP (Minimum)
Chisel (Chisel can be bought from bob)
Now that we have our supplies we need to teleport to Neitiznot.
Go to your modern spell book, click the skills teleport button, then Neitiznot South.
Walk North-East until you see an anvil and a furnace and a small hut.
Go inside and trade Bob.
This is where it starts.
Buy anywhere from 1-26 sapphires (25 ea)
Use the chisel on the uncut sapphires until you reach Level 27 crafting
You also get a little GP for each sapphire you cut
Now buy anywhere from 1-26 emeralds (50 ea)
Use the chisel on the uncut emeralds until you reach Level 34 crafting
You get a little more GP for each emerald you cut
Now buy anywhere from 1-26 rubies (100 ea)
Use the chisel on the uncut rubies until you reach Level 43 crafting
You get even more GP for each ruby you cut
Now buy anywhere from 1-26 diamonds (200 ea)
Use the chisel on the uncut diamonds until you reach Level 55 crafting
You get just a bit more GP for each diamond you cut
Now buy anywhere from 1-26 dragon stones (1k ea)
Use the chisel on the uncut dragon stones until you reach Level 99 crafting
You get the most money for each dragon stone you cut
After you cut a stone, you then sell it to the general store for a profit.
To receive maximum profit and just a bit more crafting experience you can use a gold bar on a cut dragon stone.
You then receive an Amulet of Glory (4) which sells for the most.
Each dragon stone is 1k and a cut dragon stone sells to the General Store for 7k
Each Amulet of Glory (4) sells to the General Store for 12,337 GP
It may seem like it but it does not take that long at all
This is not the best way to earn money but it is one of the top 10
Good luck my friends, I hope to see you succeed.
