* 300-320
A nice alternative to 300-315 is this pattern:
15 x [Prismatic Black Diamond] - 15 Black Diamond
When you learn these recipes, they are already yellow. I suggest you to cut 30 from any of the following gems, then you should reach 320.
[Teardrop Blood Garnet]
[Brilliant Golden Draenite]
[Solid Azure Moonstone]
[Radiant Deep Peridot]
[Inscribed Flame Spessarite]
[Glowing Shadow Draenite]

* 320-325
Make 5-7 from any of the following gems.
[Bold Blood Garnet]
[Bright Blood Garnet]
[Gleaming Golden Draenite]
[Jagged Deep Peridot]
[Luminous Flame Spessarite]
[Royal Shadow Draenite]
[Sparkling Azure Moonstone]

* 325-335
10 x [Mercurial Adamantite] - 40 Adamantite Powder, 10 Primal Earth
Make a few from any of the following gems, if you didn't reach 335.

[Enduring Deep Peridot]

[Runed Blood Garnet]
[Shifting Shadow Draenite]
[Thick Golden Draenite]
[Purified Jaggal Pearl] - This one turns green at 332.

* 335-340
Make 5-7 from any of the following gems.
[Dazzling Deep Peridot]
[Delicate Blood Garnet]
[Potent Flame Spessarite]

* 340 - 350
You can continue to make the gems above, if you didn't reach 350 by making the rings below.
10 x [Heavy Adamantite Ring] - 10 Adamantite Bar, 10 Mercirual Adamantite

* 350 - 395
Buy around 55 from any of the following gems. After 375, the recipes will be yellow so you might need less or more.
[Bloodstone]
[Chalcedony]
[Dark Jade]
[Huge Citrine]
[Shadow Crystal]
[Sun Crystal]

Cut any random gem you want. Seriously there are like 50 new green gem recipes, I won't list all of them. Go to your trainer, learn one and make that recipe around 55 times.

* 395 - 400
Make 5 from any of the following items:
5 x [Bloodstone Band] - 5 Bloodstone, 10 Cristallyzed Earth
5 x [Crystal Chalcedony Amulet] - 5 Chalcedony, 10 Cristallyzed Earth
5 x [Crystal Citrine Necklace] - 5 Huge Citrine, 10 Cristallyzed Earth
5 x [Sun Rock Ring] - 5 Sun Crystal, 10 Crystallized Earth

* 400 - 420
23 x [Stoneguard Band] - 46 Eternal Earth
or
23 x [Shadowmight Ring] - 23 Eternal Earth, 23 Eternal Shadow

* 420 - 425
You better make this yellow recipe until it turns green, because after this, there will be only meta gems, and they are a lot more expensive. Forest Emerald is usually the cheapest gem.
7 x [Dazzling Forest Emerald] - 7 Forest Emerald

* 425 - 440
Buy 15 [Skyflare Diamond] or [Earthsiege Diamond]
There are plenty of meta gem recipes, choose one of them and make it 15 times.

* 440 - 441
1 [Icy Prism] - 1 Frozen Orb, 3 Chalcedony, 3 Shadow Crystal, 3 Dark Jade

* 441 - 450
More meta gems. Usually 13-14 [Skyflare Diamond] or [Earthsiege Diamond] is enough.
