TOPIC: Gem Swap

Anyone interested in doing some gem swaps to try to fill holes in the old precious stone collection?

I need:

50 gp moonstone
50 gp onyx
30 gp obsidian
25 gp malachite
20 gp agate
20 gp azurite

Have for trade (often multiple):

75 gp amethyst
35 gp bloodstone
30 gp tiger eye
25 gp lapis lazuli
20 gp hematite
10 gp citrine
15 gp turquoise
10 gp lodestone
5 gp geo
5 gp quartz
5 gp crystal

I figure any value differences can be made up with gold.
