Remember, things on the PTR can change daily so nothing is in stone.

Here are some additions to both Jewelcrafting AND Alchemy.

There are new epic gems. They are all listed on MMO-Champion along with the new cuts that will be available.

You can now exchange badges and honor for the new epic gems.

Badges
15 Emblems of Heroism

Honor
10K honor

Another way to get the new gems is through prospecting TItanium Ore. Informal testing breaks down the gem rate as:

Epic: 25%
Rare: 25%
Uncommon: 150%
Titanium Powder: 75%

Titanium Powder can be turned in for JC Tokens to purchase the new recipes.

Alchemists can also transmute blue gems into epic gems. The current breakdown (there is currently no cooldown on the transmute but I would expect that to change):

3 Sky Sapphires -> 1 Majestic Zircon (blue)
3 Twilight Opals -> 1 Dreadstone (purple)
3 Forest Emeralds -> 1 Eye of Zul (green)

1 Majestic Zircon +2 Eternal Shadow -> 1 Amertrine (orange)
1 Majestic Zircon +2 Eternal Life -> 1 Kings Amber (yellow)

3 Eye of Zul -> 1 Cardinal Ruby (red)****

**** The transmutes are taught by the Alchemy trainer with the exception of Cardinal Ruby which is a quest. The quest for the Cardinal Ruby is to do 5 other Epic Transmutes.

I encourage you to check out the front page of MMO-Champion for a more detailed breakdown of all the new crafting yumminess. It looks like everyone (even us Chefs) got something new.

Alchemists - Pay particular attention to the new recipe, Flask of the North. Notice the comment... "Can be used in Arenas. Not consumed when used". Perma flask GOGOGOGO!

Fish Feasts will have to suffice until we get the mats for the Yogg-Saron quiche.

Nephilim Fact #174: The trash leading up to Mother Shahraz in Black Temple literally poops out enough epic gems to fill your bags. Twice.
