Cataclysm Prospecting Obsidium Ore and Prospecting Spreadsheet
We went to the auction house today and picked up 200 stacks of [Obsidium Ore] for around ~24,000g, which comes out to about 120g per stack. Although once we can find Pyrite Ore at a decent price and in good quantity, we will do a prospecting test with it. It really looks promising if Volatile Earth and gems sell for a lot on your realm. We actually used a new spreadsheet to figure out how profitable prospecting would be. On our realm, a stack should be worth 390g while the ore was selling for only 120g per stack. Assuming 100 stacks, that comes out to a 27,000g profit. The sheet also takes into account falling market prices at up to 20%. So if each stack’s worth falls to 313g, profit is about 19,000g. If you missed it, here was our Prospecting Elementium Ore With Video article.

Notes
- If plan on prospecting on a large scale, enable auto-loot and you time it right, you can start the next cast while looting the previous prospect.
- 1.5 gems produced per prospect
- 205 Hessonite and 166 Nightstone (depending on prices, these may cover the entire cost of the ore)
- We turned 60 of each color into 40 Shadowspirit Diamond
- Each gem only cost 19g each to produce, which is amazing
- The spreadsheet estimated an average of 46,000g profit from 200 stacks of ore.
- Doing some quick estimation, this prospect net close to a 50,000g profit and this is just the value of raw gems
- This basically means we doubled our investment of 24k and if we choose to cut or craft jewelery with it, this profit margin is even higher.
- Please do your own estimates, we were lucky to obtain the ore at such a good price and gems are still on the high end in our realm.
