Is it worth to craft gems?
I have been wondering for a while is it worth to craft a Radiant Star Gem from gems that we find while farming. I shall do some calculation so that we can all see at which point we should just buy from the Auction Hall.
Let’s start with a few assumption:
1) All gems we find are only “Square” gems, while “Flawless Square” is just a bonus, not taken into this calculation. We will use Ruby for this examples.
2) All gems and books (Tome of Jewelcrafting & Tome of Secrets)found are at it’s selling price to NPC.
3) All Jewel Designs are found and learned up to Radiant Star. (meaning free)
Square Ruby price: 46 gold
Tome of Jewelcrafting price: 43 gold
Tome of Secrets price: 51 gold
Step 1: You need 2 Square Ruby with 1 Tome of Jewelcrafting and 100 gold to craft 1 Flawless Square Ruby, totalling the cost 46+46+43+100 = 235 gold
Step 2: You need 3 Flawless Square Ruby with 3 Tome of Secrets and 30,000 gold to craft 1 Perfect Square Ruby, totalling the cost (235×3)+(51×3)+30000 = 30,858 gold
Step 3: You need 3 Perfect Square Ruby with 6 Tome of Secrets and 50,000 gold to craft 1 Radiant Square Ruby, totalling the cost (30858×3)+(51×6)+50000 = 142,880 gold
Step 4: You need 3 Radiant Square Ruby with 9 Tome of Secrets and 80,000 gold to craft 1 Star Ruby, totalling the cost (142880×3)+(51×9)+80000 = 509,099 gold
Step 5: You need 3 Star Ruby with 12 Tome of Secrets and 100,000 gold to craft 1 Flawless Star Ruby, totalling the cost (509099×3)+(51×12)+100000 = 1,627,909 gold
Step 6: You need 3 Flawless Star Ruby with 15 Tome of Secrets and 200,000 gold to craft 1 Perfect Star Ruby, totalling the cost (1627909×3)+(51×15)+200000 = 5,084,492 gold
Step 7: You need 3 Perfect Star Ruby with 20 Tome of Secrets and 400,000 gold to craft 1 Radiant Star Ruby, totalling the cost (5084492×3)+(51×20)+400000 = 15,654,496 gold
In Conclusion, if you find the price is lower than Auction Hall, it worth while to craft, while price higher, just buy from Auction Hall!
