This can provide an extra layer of information for your players or even to create a famous and sought after gem. What do you think would be more interesting, a simple large ruby, or one shaped like a star but feels oddly warm to the touch…?
The Gemstone Generator is for providing details about the gem itself - Building on the existing gemstone rules it adds more detail and introduces the G7+ gemstones - They look like others at first glance but behave very differently.
This generator takes the information found in Pathfinder® Roleplaying Game: Ultimate Equipment™ and expands on it, giving you details on the gem itself. Therefore, you will need this book to make full use of this product.
