Bling a ding ding
So… apropos to the almost geological pace at which I write for this here blog, I thought I'd de-cloak and share some tables I recently put together to help me when I'm keying up dungeons and gemstones pop up in a treasure stash. I like to give treasure a bit more character than its simple GP value, but I like to stick to Labyrinth Lord's tables and I didn't have a good specific randomizer, so I made one.

These are distilled from some gemstone posts Jeff Rients made a few years back that I stumbled on while whiling away a dull afternoon at work by hitting his "random post" button. He, in turn, I believe, distilled them from Gygax in the 1st Edition AD&D Dungeon Masters Guide. So there you are. (Here are Mr. Rients original posts, which have some very handy visuals:Ornamental Stones, Semi-Precious Stones, Fancy Stones, Precious Stones, Gem Stones, Jewels)

I reorganized the sources a bit, spread them out over the different value levels on the treasure tables I use, and added some tables to embellish and give the gems more character if desired. These are calibrated for Labyrinth Lord, and are included under the good ol' OGL.

If you can make use of 'em, cool. Enjoy.
