There isn't! So here goes
Hopefully I haven't missed anything, if anyone spots any mistakes or anything missing then please let me know!
Note that for most of these, socket items can all be combined, 3 of the same size makes 1 of the next size up, with some exceptions
For individual element damage ones...
Dark Damage = Almandine
Holy Damage = Tanzanite
Fire Damage = Ruby
Ice Damage = Sapphire
Lightning Damage = Topaz
0.3% = Cracked...
0.6% = Flawed...
1% = ... [Level 60+]
1.5% = Flawless... [Level 100+]
2% = Perfect... [Level 140+]
3% = Perfect(E)... [Level 180+]
There's also Emerald which does poison resist and follows the same cracked, flawed etc., but with different percentages
Also elemental damage covers all elements so can be really useful if you use multiple elements in your attacks
0.8% Elemental Damage (all elements) BlueDisciplineGem
1% Elemental Damage (all elements) GreenDisciplineGem
HP/MP runes come in various sizes
HP+ = HealthRune
MP+ = ManaRune
XS = +80
S = +100
M = +120
L = +150
XL = +300
Damage sockets have the same size ranges as HP/MP ones
MC = MagicCrystal
SC = SoulCrystal
DC = BraveryCrystal
XS = +2
S = +4
M = +6
L = +8
XL = +10
XL(E) = +15
MA/SA/PA have changing names over the sizes which is confusing to some people
MA+0.3% = IthRune
MA+0.4% = SurRune
MA+0.5% = BloodstoneMarble
MA+0.8% = DamagedArcaneRune
MA+1% = ArcaneRune
MA+1.5% = ArcaneRune(E)
SA+0.3% = TalRune
SA+0.4% = BerRune
SA+0.5% = HematiteMarble
SA+0.8% = DamagedSpiritRune
SA+1% = SpiritRune
SA+1.5% = SpiritRune(E)
PA+0.3% = NefRune
PA+0.4% = OhmRune
PA+0.5% = AzuriteMarble
PA+0.8% = DamagedFuryRune
PA+1% = FuryRune
PA+1.5% = FuryRune(E)
Acc/Agil ones have weird names too!
Acc+3 Agil+4 = Accuolite
Acc+4 Agil+5 = Accuonite
Acc+5 Agil+6 = Agilonite
Then you have some various miscellaneous ones
Note that these ones cannot be combined to make larger ones
Magic Defence 1% = Citrine
Physical Defence 1% = Chyrsocolla
Magic Damage Reduction 1% = UnakiteStone
Physical Damage Reduction 1% = FluoriteStone
MP Regen 10% = ManaRegenRune
