Treasure: Fancy Rocks, Gemstones

AD&D wise this stones would be 1 bv to 10 bv at normal sizes. Carved they would be worth much more. None the less they would be the bottom of the gemstone list.

Ornamental Gems

At any rate, the substantial cost of a gem is not in its location. As anyone knows who has bought a rock tumbler, the cost of gems is in the finishing.

Here are a list of ornamental stones, with visual aids and links. They are all, in my reckoning, worth about the same amount, and represent the lowest echelon of 'gemstones.' Some of these are included in the DMG; some are listed as 'fancy' gems in that very flawed book, a rating I contest. But the gentle reader is certainly permitted to contest me.

I've tried to show the gems in their most ordinary, polished state, but that wasn't always possible given the pictures I found on the net. You can search for yourself if you like, there are plenty of images showing these from their raw state to quite marvelous pieces of jewellery. Most of these stones are made valuable because they are able to be carved, rather than simply polished and set.

The only specific information I'll add to the links would be a list of sources where the gemstone would be found in my world. None of these lists are meant to be exhaustive, they simply include those places for which I have reputable sources. To make it comprehensible, I will use the regional names normally associated with Earth, and not what I call them my world.

A last point. Many of these below are lesser quality examples of superior quality gems - such as cat's eye, which is a form of chrysoberyl, or prase, which is a form of chrysoprase; in both cases, purer chrysoberyl and chrysoprase are much costlier gemstones (and I may present those at a later time).
