Gems are classified as:

- Based on grade: Common, Rare, Epic, or Legendary

- Offensive or Defensive

- Descriptively as Gem, Jewel, Stone (not sure if other words used too, and haven't looked into if it ties to powers or is just randomly chosen word)

- Based on Element: Earth, Wind, Fire, Water

Eg. Epic Offensive Gem of Wind Fury

Primary property for all gems is Elemental Pierce or Elemental Resistance, so based on primary property we have gems of:

- Earth Fury, Earth Resistance, Wind Fury, Wind Resistance, Fire Fury, Fire Resistance, Water Fury, Water Resistance

These probably should be taken off of the random property table, made into separate Elemental Pierce / Resistance table, as one of them is applied always and they define whether gem is offense/defense (ie. can be slotted to weapon, armor, and so on), and second elemental pierce/resist can't appear as random property ever.

The other properties are random, although I don't know which ones are excluded from Legendary gems (IIRC some were, but could be wrong here) nor whether any of them excludes another (eg. can a single gem have both physical pierce and physical resistance?)
