Overview

Gems (and coal) are acquired when ore stones in a mine are broken (by being used in 7 workloads). The size of the gem is random. There is some evidence to suggest that when more ore stones are broken in the same set and/or workload, the gem sizes on average tend to be larger; however, it's still perfectly possible to pull a Huge gem without exploiting this. Sand mines are thus valuable for gem mining, as it's easy to plan in such a way as to break 5+ nodes at once (assuming there are 5 different colors present in the field).

Below are some step-by-step guides for how to get the most gems per workload for various workload configurations.

For the basic mechanics of mining, please refer to the Mining Guide.

Workload Configurations

Six Colors

For a workload distribution of 5 single colors, and then 1 pairs of colors, you can achieve the crumbling of all seven ore stones by following the pattern as laid out below:

Sets A-1, B, C, F A-1, D, E A-1, C, D, E A-1, B, F A-1, D, E, F A-1, B, C A-1, B, E, F This workload will crumble stone A-1 A-2, C, D A-2, D, E A-2, B, C, F A-2, C, F A-2, B, E, D A-2, B, E This workload will crumble stone B & E A-2, C, D, F This workload will crumble the remaining stones

Six Colors (Alternate)

It is also possible to form a group of 6 that breaks all at once, if desired.

Sets A-1, B, C A-1, D, E, F A-1, B, D A-1, C, E, F A-1, B, E A-1, C, D, F A-1, B, F Breaks A-1 A-2, C, D, E A-2, B, C A-2, C, D A-2, D, E A-2, E, F A-2, F, B A-2, B, C, D, E, F Breaks the remaining 6

Five Colors (Two Pairs)

For a workload distribution of 3 single colors, and then 2 pairs of colors, you can achieve the crumbling of all seven ore stones by following the pattern as laid out below:

Sets C, D, E C, A-1, B-1 C, A-1, B-2 C, A-2, B-1 C, A-2, B-2 D, A-1, B-1 D, A-1, B-2 D, A-2, B-1 D, A-2, B-2 E, A-1, B-1 E, A-1, B-2 E, A-2, B-1 E, A-2, B-2 A-1, B-1, C, D, E Breaks A-1 & B-1 A-2, B-2, C, D, E Breaks the remaining 5 stones

Five Colors - Alternate Method

Using the theory that gem size is tied to the number of stones broken in a single workload (as opposed to the number of total stones broken in a field), the above can be simplified to do a little less work and still get the big break that will be producing most of the big gems.

Refer to the above image.

First, choose one of the duplicate-colored stones to ignore completely. Here we'll choose B-2. Then pick one of the stones in the remaining pair (say, A-1) to be your starter stone. Make any valid 3-stone workload starting with your starter stone, and immediately follow that with the workload consisting of the remaining 3 stones. There are exactly 6 sets of these pairs of workloads. Do them all.

A-1, C, D	A-2, B-1, E
A-1, C, B-1	A-2, D, E
A-1, C, E	A-2, D, B-1
A-1, D, B-1	A-2, C, E
A-1, D, E	A-2, C, B-1
A-1, B-1, E	A-2, C, D

And finally choose a 5-stone workload (either A-1 or A-2 in addition to B-1, C, D, and E).

The same process can be applied to 6- and 7-color fields. Make 6 sets of complementary pairs of workloads, and then one big one to break them all.

Five Colors - (Triple)

A triple and five single colours allows us to break 5 stones, which can be done all at once.

Sets A-1, B, C A-1, B, D A-1, B, E A-1, C, D A-1, C, E A-1, D, E A-2, B, C A-2, B, D A-2, B, E A-2, C, D A-2, C, E A-2, D, E A-1, B, C, D, E Breaks all these 5 stones

Four Colors - Configuration 1

With three pairs of colours all stones can be broken, in a group of 3 and a group of 4.

Sets A-1, B-1, C-1 A-2, B-2, C-2, D A-1, B-1, C-2 A-2, B-2, C-1, D A-1, B-2, C-1 A-2, B-1, C-2, D A-1, B-2, C-2 A-2, B-1, C-1, D A-2, B-1, C-1 A-1, B-2, C-2, D A-2, B-1, C-2 A-1, B-2, C-1, D A-2, B-2, C-1 This will break all 3 stones A-1, B-1, C-2, D This will break all 4 stones

Four Colors - Configuration 2

With a triple and a pair of colours it is possible to break 4 stones, which can be done all at once.

Sets A-1, A-2, A-3 A-1, B-1, C A-1, B-1, D A-1, B-2, C A-1, B-2, D A-1, C, D A-2, B-1, C A-2, B-1, D A-3, B-1, C A-3, B-1, D A-2, B-2, C A-2, B-2, D A-1, B-1, C, D Breaks these 4 stones

Three Colors - Configuration 1

When we have a triple and two pairs of colours, no stone can be worked seven times. Just do a few workloads to speed up resetting the mine.

Sets None.

Three Colors - Configuration 2

When there is a quadruple and a pair of colours, only the single stone can be broken.

Sets A-1, B-1, C A-1, B-2, C A-2, B-1, C A-2, B-2, C A-3, B-1, C A-3, B-2, C A-4, B-1, C
