Another handy reference book from Bards & Sages. As with Elemental Metals, gemstone's elemental alignments, availability of the gemstone and some information (such as how the stone may usually be used as a luck charm for example) is provided as well. Very handy for item creation or for adding a little "extra" information/color/etc. as you like. Definitely a time-saver for the GM who needs detail but who hasn't got the time to do the research on their own. Each pictured gem is shown in one of a variety of formats (either cut and set in jewelry, tumbled/polished or raw). Ideally I would have liked to have seen two pictures per gem, one each as raw and finished. If you liked Elemental Metals, I'm certain you will enjoy this too.

A handy little reference book. Short entries about a variety of metals keep information easy to get at (such as elements associated with the metal and how readily available the metal is). Probably most useful for creating unique items for your games (they can't all be silver relics, can they?), but could add some flavor when your group's mage(s) cast various "detect [...]" spells on things (now instead of saying, "You can tell it's a brass figure worked by the hands of a dwarf" you can say "It's a brass figure worked by the hands of dwarf and resonating with a strong aura of fire.").
