Possible locations for random gems (all using the loot leveled list) are: The following table illustrates the possible outcomes of a single gem 'loot roll' at different character levels. The leveled list is weighted so that the chances of high-level gems continue to increase as your level improves (e.g., flawless garnets are two times more likely to appear at level 6 than level 4), but there is always a chance of receiving even the lowest level gems. Merchants do not stock diamonds, emeralds, or any flawless gems. The 'Level (Loot)' column in the following table applies to most locations where gems are found the 'Level (Merchant)' column only applies to merchant inventories. The gems that appear in randomly-generated loot depends on the player's level. Most gems that you find are randomly generated, meaning that most of the possible locations are the same for all twelve types of gem.
