Huge gems are rare. They've always been rare. They are even more rare now that most people get ores via auto-mines. (You only find gems if you mine by hand).

Basic gem information

If you can't find someone to sell or give you a huge gem, you can always try to find one yourself. There are some 'tricks' to doing this.

• Gem deposits are built around 40 x 40 coordinate blocks starting at map coordinate 0,0. So this means that all mines built between 1,1 and 39,39 will produce the same type of gem. It doesn't matter if the mine is at 1,1 or 1,10 or 17,12 or whatever. Any mines built in the same 40x40 block will produce the same gem type.

• You only get gems by working a mine manually (or using a macro on it). Auto-mines don't produce gems.

• When you first build a mine, the computer determines how frequently the mine will produce gems. Some mines are awful gem mines and will produce gems less than 1 pull in 100. Some mines are great gem mines and will produce gems as often as every 6 or 7 pulls. You won't know how good a mine is until you build it and do about 100 pulls on it. There is no way to improve the rate as which a mine will produce gems.

• If you tear down a mine and rebuild a new mine in the same spot, it can change the gem pull rate.

• If you tear down a sand mine, you get salvage back from it (assuming you have salvage trained). If you tear down an ore mine, you don't get any salvage in return. Make sure you have salvage trained to 3+ before you go looking for huge gems.

• If you build a new sand mine on the same spot as an old sand mine, the new mine starts as a level 1 mine. This is true regardless of the level of the old sand mine. If you build a new ore mine on the same spot as an old ore mine, the new ore mines starts at a higher level than the old mine.

• Use mining food when mining gems. It goes much, much faster and there are pretty cheap cook4 recipes for mining food. Chat your favorite cook -- or even me -- if you are stuck and can't find one. Good mining food should boost your strength and perception by at least 8 points each. Don't worry about the other stats.

Procedure to find gems

To find huge gems, you can put all these tricks together and do the following steps:

1. Figure out the huge gem type you want. Is is Rubies or Topaz or something else?

2. Ask your friends, neighbors or others in your region for the location of a 40x40 block that produces the gem type you want.

• If you can't get someone to tell you the location of a gem block, then load up with the materials for 3-4 mines and head out to an open spot in the wilderness. Look at your map coordinates and divide by 40 to figure out what 40x40 block you are in. (For example, if you are at -1320, +4287 then -1320/40 = -33 and +4287/40 = +107 so you are in block -33, +107)

• Build a mine. It will probably be a sand mine. This is good. Hand mine it a few times until you get a gem. Is it the gem type that you want? Probably not. So salvage the mine but record the type of gem produced by that location. Then move to the next gem block (by going either north, south, east or west 40 coordinates) and build a new mine. Test it. Is it the type of gem you want? Probably not. Salvage it and move again. It can take a few dozen mines to locate all of the basic gem types -- and several dozen more to locate diamonds. But since you get to salvage after mine after you build it, you'll get back most of your materials. With some patience, you can find blocks for all gem types.

3. Once you find the location of the correct gem block, build one sand mine. You might be tempted to build more but one is plenty. Now go eat your favorite mining food and mine 100 sand from your new sand mine. After 100 sand, look at the mine to see how many gems it produced. If it's less than 10 gems, tear the mine down for salvage and build a new one in the same spot. Mine a 100 sand from it. This goes *very* fast with mining food. Depending on your luck, you'll probably have to rebuild 2-5 times before getting a mine that yields 10% or more in gems.

4. Now that you have the right gem type and a good gem producing mine, work it! Work the mine until it collapses and repair it. Then work it more. Most good gem mines will kick out a huge gem every 2-4 repairs. If the mine goes more than 5 repairs without making a huge, tear it down for salvage and build a new one.

This whole process does take some time and effort but it's possible for even a relatively new player. I found all my own huge gems in this game -- as well as a few dozen more that I sold or gave away -- within my first two months in ATiTD and before I even was level 20. You just need some salvage skill, some patience, the ability to keep track of map coordinates, and decent mining food.
