What the random gemstone generator rolls
For game treasure, it rolls a set of gems with a type, a cut, a size, a value in gold pieces and a short description you can read to the players. Give it a total value and it makes the gems add up to about that amount. For real gems, it picks a gemstone and gives its mineral family, colors, hardness, where it is mined and one fact.
Gem treasure for your game
Use it for a dragon's hoard, a merchant's lockbox, a pickpocket's lucky find or a reward at the end of a quest. Ask for cheap gems for a low-level party or a single priceless stone. Add a quirk or story hook if you want the gem to lead to the next adventure, then pair it with the magic item and quest generators.
Learn about real gemstones
Ask for a random real gemstone and learn something new about minerals, from common quartz varieties to rare stones. To find out what a stone you own might be from a photo, the gemstone identifier is the tool for that. Gem values in treasure mode are for games only, not real prices.
