Gemstone piece

The Gemstone piece is a part of the artefact Gemstone found in the level The Colosseum in Tomb Raider Chronicles.

There are actually two different Gemstone pieces to be found, and when they're combined, they form the Gemstone.

Locations of the Gemstone pieces

The first Gemstone piece is found on a pedestal after climbing up a ladder from the room with lion cages
The second Gemstone piece is on a pedestal that raises from a round platform when Lara pulls a pullrope three times. She then has to make a timed run to the piece by running and hopping along ledges.
