The Gem of Quon is one of the most valuable gems ever dug up on the world of T'Lohrcate. Something of a local legend on the planet, it was found in the mines owned by Yarlon and has been in his possession. Others have coveted the gem, some even trying to steal it, though none succeeded. Philo is infamously know in his efforts in trying to buy the gem off Yarkon, but his offers have been rebuffed by Yarlon out of spite.
