Thanks to the Freedom Knights fearless leader from whom I snagged this...but he snagged this from eq2traders. Lol I lost track of what rare was for what after the tradeskill update as I am sure some of you did too. 
Here is a list of rares harvestables I found on EQ2 trader, thought I would get it here so it may be of some help to us all.
What To Do With Your Rares
This is intended to be a lay person’s guide to rare harvested items and to what to do with them when found. You don’t need to be an artisan to benefit from this guide (in fact I assume most artisans have proably learned most of this while working) but you are best off if you know people to work with, such as guildmates, who can help you with producing items from your rare harvests. This is what you need to know about what they do in order to work with them. (This information has been updated to reflect LU24 changes.)
Rare Ore
* Bronze Cluster (tier one)
* Blackened Iron Cluster (tier two)
* Steel Cluster (tier three)
* Feysteel Cluster (tier four)
* Ebon Cluster (tier five)
* Cobalt Cluster (tier six)
* Xegonite Cluster (tier seven)
These can be forged into weapons, chain or plate armor, kite or tower shields, tablets (jewelcrafted item) and furniture (lights for tiers 1-5, other pieces in T6 & T7). The armor and weapons created will be attunable and hence usable only by one owner. Remember, however, nice though a bronze weapon might be, for a level 7 character, you'll outgrow it pretty fast.
Rare Pelts
* waxed leather pelt (tier one)
* cured leather pelt (tier two)
* cuirboilli leather pelt (tier three)
* engraved leather pelt (tier four)
* augmented leather pelt (tier five)
* scaled leather pelt (tier six)
* dragonhide leather pelt (tier seven)
These can be tailored into leather armor for brawler types, druids, etc., backpacks, as well as ranged/ammo items (quivers, sacks, bandoliers, satchels, etc.). Rare packs will have a higher weight reduction and 2 extra slots over their non-rare counterparts (T7 will have +4).
Rare Wood
* Severed Alder (tier one)
* Severed Bones (tier two)
* Severed Fir (tier three)
* Severed Oak (tier four)
* Severed Cedar (tier five)
* Severed Ironwood (tier six)
* Rough Lumbered Ebony (tier seven)
This can be made into wooden weapons, bucklers, roundshields and bows by a woodworker. It can also be turned into rare furniture with a higher status rent reduction on it, by carpenters.
Rare Roots
* Yarrow (tier one)
* Sisal Root (tier two)
* Raw Dandelion (tier three)
* Oak Root (tier four)
* Figwarts Root (tier five)
* Saguaro Root (tier six)
* Nimbus Root (tier seven)
Can be tailored into cloth armor for caster types, hex dolls (tiers 2-7). Carpenters can turn it into rare rugs and paintings, and jewelers can turn it into scarves.
Rare Gems and Metals
* Rough Lapis, Copper Cluster (tier one)
* Rough Coral, Silver Cluster (tier two)
* Rough Jasper, Palladium Cluster (tier three)
* Rough Opal, Ruthenium Cluster (tier four)
* Rough Ruby, Rhodium Cluster (tier five)
* Rough Pearl, Vanadium Cluster (tier six)
* Rough Moonstone, Acrylia Cluster (tier seven)
These are some of the most sought after rares, and some of the most confusing. Rare jewelry and ranged items can be made from them, which are worthwhile to consider, especially at the higher tiers. In tiers 6 and 7, they will also make furniture. Their main use, however is in adept III spells/skills, and this is where the confusion comes in.
Tier 1 and 2 adept IIIs for scouts, priests and mages use the gem rare (lapis, coral). Tier 3 and above use the gems for priest adepts, and the soft metal for mage adepts, while scouts get rerouted over to the loam.
Rare Loams
* Solidified (tier one)
* Alkaline (tier two)
* Malleable (tier three)
* Ductile (tier four)
* Fused (tier five)
* Alkalai (tier six)
* Spongy (tier seven)
Loams are a newer harvest from ore nodes, and one that still confuses many folks. In tiers 1&2, the rare loam is only used for fighter adept IIIs. In tiers 3 and above, the rare loam is used for both fighter and scout adept IIIs.
Imbue Rares
* Glowing ____(tier two)
* Sparkling ___ (tier three)
* Glimmering ___ (tier four)
* Luminous ___ (tier five)
* Lambent ___ (tier six)
* Scintillating ____ (tier seven)
These items can be harvested off the various nodes, and the second half of the name will vary depending on what node you harvest it from. (Tooth from dens; flower from gardens and wood; stone from ore and stone nodes.)
There are recipes for many lovely imbued items, scattered across many crafting professions: shields, weapons of all types, chest and leg pieces from base armor sets, and rings. In each of these cases, the crafter takes a pristine version of the item in question, along with an imbue item and a fuel, and makes an imbued version of the item which has a proc of some sort upon it. Hex dolls, which also require imbue materials, have a slow-casting spell effect upon them, but you craft the raws directly into the finished doll, instead of making a finished product, then applying the imbue materials.
Magic Dust?!
* Flickering (tier one)
* Shimmering (tier two)
* Sparkling (tier three)
* Glimmering (tier four)
* Luminous (tier five)
* Lambent (tier six)
* Scintillating (tier seven)
The creation of any adept III of any type now returns dust as a byproduct (pristine-level combines should return 2 dust). This dust is used only by alchemists, in the creation of rare potions and poisons.
How To Use Rares
Basically, if you want to use rares yourself, you need dropped books to do it. Especially in the lower tiers, the advanced books drop mainly from mobs that are the exact same level as the volume number, but this can vary as you progress to the higher levels. For more information on rare recipe books and how to get them, see the Recipe Books - The Goood, the Bad and the Necessary guide.
Keep close contact with your artisan guildmates and friends if you are hoping to find someone to craft rare items that you are unable to craft for yourself. They need your support. Stay organized and hopefully when you finally do get that rare harvest it will translate into a nice piece of equipment for you. Otherwise, at least, this guide should help you to know what’s really valuable.
Tier 1: Queen's Colony, Outpost of the Overlord, Forest Ruins, Oakmyst Fores, the Caves, the Peat Bog, the Ruins, the Sunken City, the Sprawl, the Graveyard. (the Sprawl and the Graveyard have no fishable spots) Tier 2 - Antonica, Commonlands, Vale of Shattering Tier 3 - Thundering Steppes, Nektulos Forest, Zarvonn's Tower Tier 4 - Enchanted Lands, Zek, Cove of Decay, Bloodskull Valley Tier 5 - Rivervale, Feerrott, Everfrost, Lavastorm Tier 6 - Sinking Sands, Pillars of Flame Tier 7 - Tenebrous Tangle, the Barrens, the Bonemire (node types will vary based on the island that you are on, and not all locations contain all types of nodes)
