Jewel Crafting

Summary

 * The Jewelcrafting floor unlocks at Area 50 and costs 500K coins
 * Most crafted jewels serve no practical purpose. Only Emeralds, Sapphires, and Diamonds are used in crafting recipes, while Polished Amber is used to reach Tier 2 Jewelcrafting.  The other gemstones are only used in some combination of fulfilling quests, reaching specific player levels, and making trade goods for profit (on the trading floor).

Note that trading floor recipes are unlocked when you visit the appropriate location, but can't be used until you unlock the underlying polished item(s). All are listed at both the minimum (level 1 trading floor) and maximum (level 100 trading floor) amounts for 5:45 am.

Note that because some of the items above require you to make items on the jewel crafting floor in order to make them, their real best crafting time is reduced, unless you spend your time on the base first and the item second - making both at once limits you. These items are listed below, with as good a setup as you can make with 8 stations. The table above lists setups where you set all of your stations to make the inputs, then toggle over to make the outputs, and vice versa, but that is more hassle.

What this means in practice for the trading floor is that Haircombs and Obsidian will run you nearly the same profit per second, but the Haircombs won't also demand your greenhouse do any work, so your real profit per second with the jewel crafter + trading floor is generally haircombs, provided you also use your greenhouse to make a profit.
