Bag of Gems
From WikiRaider
The Bag of Gems is found in Lara Croft and the Temple of Osiris. Occasionally, after beating a large number of enemies, like in a combat challenge or in the struggle against countless Green Scarabs and Fire Scarabs in the Tomb of the Timekeeper, Lara is awarded with a bag of gems, when she runs over the bag, it breaks and the gems spill out, ready to collect.
In the level Tomb of the Timekeeper a bag of gems serves as bait to get Lara onto a Retracting Ledge.
