WOW Patch 5.2 Jewelcrafting Changes

　　Making 100 blue gems will cost you 83 Golden Lotus and 83 assorted green quality gems (again, 120 without procs from step one)
　　Compare this to the new Primal Diamond recipe, which will require 5 of each uncut green gem: a stack of 20 would require 600 green uncut gems and 20 Spirits of Harmony. Depending on what you do with your green gems, this may or may not be worth it at all.
　　One common thing to do with green gems is make greens for disenchanting or vendoring. One of each color green quality gem (also known as the average yield from a single stack of Ghost Iron Ore) makes two greens, one ring and one neck. These have a 10% chance of proccing a 415 blue with a random enchantment that can be used as low as level 85. The blue Ornate Bands sell for an average of 100g on my realm, and the blue Shadowfire Necklaces are closer to 50g (with many of them ending up disenchanted).
　　If you use one of each green gem to make two items and vendor them both, you just made about 20g. If you make 600 green gems worth of them (which is what you could have done instead of making a stack of meta gems), you'll usually end up with 20 blues and 180 greens. On my realm, those blues are worth 2000g total, and the greens are worth either 1800g at the vendor, or double that (3600g) as enchanting materials. Your mileage will, of course, vary (unless you're on my realm).
　　In short, in order to make that stack of meta gems, you can either:
　　Use 83 Golden Lotus and 83 of the three colors of green quality gems you'd need
　　Use 20 Spirits of Harmony, worth at least 40 Golden Lotus at the vendor plus 600 green quality gems, worth a lot of gold.
　　If the money you're losing from not buying Lotus with your Spirits of Harmony is 2000g and you can make 5600g from those 600 green gems, using the new recipe costs you 7600g for a stack of meta gems.
　　If you buy 83 lotus from the AH for 4150g and the 83 green quality gems you'd use with the transmutation method are worth 775g, a stack of meta gems cost you just under 5k gold without the new recipe. I am glossing over the fact that you only need three colors of gems for this method, rather than an equal number of all colors consumed by the spirits. Since we can only compare for "small" quantities (it takes a long time to farm Spirits of Harmony), dealing with the imbalance generated by this doesn't take a lot of time.
　　If the price of Lotus is lower, it favors the new recipe even less, however if enchanting materials are dirt cheap, it may favor the new recipe. If instead of making 5600g from those green quality gems, you can only make the vendor floor from them (2000g assuming you vendor the blues), you would have to recalculate. That said, this recipe uses Spirits of Harmony. It's supposed to be unambiguously good, not good on some realms sometimes.
