The Sims 3 Guide - Sunset Valley
Collectibles - Gems
While gems may not sound as interesting as Butterflies or Beetles, they can be even more valuable. They take a little more work to make them ready for sale in your inventory. You would be wise to get a gem cut, as this increases its value, possibly tremendously – though it costs a lot in itself. As you collect more and more gems, more highly specialised cuts become available, with the most advanced increasing the value of a gem five times over, though it does cost 1,000 Simoleons. You send the gem to be cut via the mailbox on your house's lot. You can then sell it by dragging it into the sell section of your inventory (marked by a faint Simoleon symbol).
Sending a gem off to be processed.
Below is a list of the gems and their value before they are cut. You can then send them off to be processed and it will increase their price. Clearly however, for the more common gems the price of the professional process is far greater than the value of the gem, so be careful. Price also varies by the weight of the gem, though never by more than about fourty-percent of the prices listed below.
Aqua: 21 Simoleons
Smoky: 25 Simoleons
Emerald: 30 Simoleons
Ruby: 35 Simoleons
Yellow: 60 Simoleons
Tanzanite: 95 Simoleons
Diamond: 200 Simoleons
Special: 350 Simoleons
Rainbow: 700 Simoleons
Pink: 1,650 Simoleons
The Pink Gem is only found in one place, and that is at the start of the cliffs on the eastern part of the beach. It must be accessed from the road above, the one that goes past Little Corsican Bistro heading out of town to the east.
The Rainbow Gem can be found in the deposits by the Summer Hill Springs, among the cliffs between Pinochle Pond and Fort Gnome Military Base, and the cliffs by the beach, below the coastal road.
Finding a gem
The Special Gem can be found in the deposits on the coastal road going out of Sunset Valley to the east, down the hill from Crystal Springs.
Gems can turn out to be Mysterious Mr. Gnomes, when analysed.
