Raw
Gemstones are found in the rough.


 * How rare is Rainbow Gem and Pink Diamond?
 * Case 1: Total of 272 Gems, 225 Metals and 97 Rocks were collected before 1 Pink Diamond and 1 Rainbow Gem spawn


 * From Case 1, estimated chance to collect BOTH rare gems is about 0.33% ( 2 / 594 )


 * Case 2, approximately 3-5 gems found before 1 Pink Diamond was found.

Keep collecting ALL gems (regardless of the value of it) on the entire map and they will spawn somewhere eventually.

Pink Diamonds can also be found in the Catacombs at the Graveyard, not very rare there.

Cuts
Gems may be sent to the gem-cutter and cut into the following cuts. You start with the Emerald cut, and gain cuts by cutting gems.

Sometimes the gemcutters will return an uncut gem, saying that it is actually a Mysterious Mr. Gnome in disguise.

The table lists both when you break even with a particular cut, and when a cut begins yielding better profit than the previous cut.

For example, if a gem is worth §47, an oval cut provides §70 while the Pear cut yields §82. Factoring in the cost of the gem and the cost of cutting the gem, the Oval cut provides a §3 profit while the Pear cut yields no profit. The Pear cut does not start providing more profit than the Oval cut until the original worth is §60, as listed below.

Metals
Metals are found in ore form, and can be smelted into ingots for §40.

Sometimes the foundry will return an ore, saying that it is actually a Mysterious Mr. Gnome in disguise.

Smelted ingots are worth 175% of their original cost, and so the raw metal must be worth §54 to break even.

Rocks
These are meteorites, space rocks that have fallen from the heavens. They come in three varieties: Tiny, Large and Gigantic 2x3 Space Rock(spotted via the telescope "at least that is what my sister did") it is also possible to find gigantic space rocks in trash cans. Initial appraisal appears to be based on their weight, so naturally Large Space Rocks are worth more than Tiny Space Rocks. However, your sim may Analyze a space rock, which will result in it being one of the below types. Each type may be worth more or less than initial appraisal. Finding half the rocks makes it easier to find the other half, and finding all the rocks results in finding the more expensive ones more often.

Rocks can be found using the "Rocks and Gems" setting on the Collection Helper. Your sim may also spot a meteor falling while using the telescope, which will mark its position on the map. Sometimes when buying a house an event will pop up that the house you purchased was struck by a meteor, and ask if you want to accept the challenge. Doing so results in several Large Space Rocks and Tiny Space Rocks scattering the home (along with fire damage).
