Gem collecting

Gems are collectibles in The Sims 3. They are found in their raw form and can be cut by sending them to a gem cutters or by using the gem cutter machine.

Raw
Gemstones are found in the rough, around neighborhoods and on adventures.

Tiberium


Tiberium is an extraordinarily rare and potentially very valuable gem. It represents the Tiberium crystal in Command And Conquer: Tiberium Wars. The raw rock is worth §75-125. In the inventory (either as ore or cut) it will give a negative "Visceroidal Nausea" moodlet (-25 mood).

Tiberium can be cut into 2 different forms:
 * Small Spire Cut (§6,500)
 * Heart-Shaped Cut (§1,000)

No matter what the cut is, Tiberium will grow into a Large Spire Cut within a day, giving it a value of around §40,000 or higher in some cases.

Cuts
Gems may be sent to the gem-cutter and cut into the following cuts. Starting with the emerald cut, and Sims gain cuts by cutting gems.

Geode & Septarian Nodules only have polished split and heart-shaped cut, while Tiberium only has Spire and Heart-Shaped cut

Sometimes the gem cutters 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.

The star-cut will be enabled after installing patch 26 or The Sims 3: Pets, otherwise it will be hidden from normal gameplay and cannot be produced by players but they can be found in tombs. A glitch that may be caused by testingcheatsenabled true is that when you are returning from any world causes all gems to become blue topaz in color. This can be fixed by restarting, although the glitched gems will stay blue.
