Gems
- This article is about the gems produced from ore and sand mines. See also Cuttable Gems.
Gems are a product (or by-product) of Mining. There are six known types -- diamond, emerald, quartz, ruby, sapphire, and topaz -- with quartz being by far the most common. An individual Mine produces one type of gem, but the gems can be of any size. The gem rate (how often a mine produces a gem) is specific to a mine, and seems to be randomly determined when the mine is built.
If you tear down and rebuild a sand mine, it appears to randomly reset the gem rate. Note that this will require additional materials to rebuild the mine, depending on your Salvage Techniques skill. Tearing down and rebuilding an ore (non-sand) mine does not affect the gem rate, as tearing down an ore mine does not completely destroy it (see the Mine page for more details).
Gems are distributed in 40x40 coordinate "blobs", with blob boundaries being divisible by 40. So the square formed by (0,0) and (40, 40) forms one blob. (39, 39) would be in this blob, but (41, 39) would be in another. All mines dropped within a blob will yield the same gem type, with quantity varying by mine as explained above. All blobs will yield at least quartz. It is theorized that rarer gem types tend to cluster, so if one blob is producing ruby, check the neighboring blobs to look for topaz or emerald, for instance. The exact pattern of gem types isn't known, but it is theorized that some travel in "veins" like iron and copper, while others cluster in "mega blobs".
The quantity of the different sizes of gems you get seems to follow a 7 base, just like many other activities in the game. So after mining 100 huge quartz, you would expect to have 700 large quartz, 4900 medium quartz, and 34300 small quartz.
