Precious Stones, base 500gp value

Aquamarine

The bluest aquamarines are called 'maxixe' (don't ask me how that is pronounced). Maxixes fade to white in sunlight or when heated.


Violet Garnet



Black Pearl




Peridot can be found in some meteors.


Blue Spinel



Topaz

Like many gems, topaz comes in a bewildering variety of colors.  The rainbow-hued center specimen here is 'mystic topaz', which is colorless topaz that has been artifically treated.*
*In my limited research it seems that a lot of modern gem stones are treated or irradiated to bring out a color they wouldn't have had in earlier periods of history.  Unless you believe the Knights Templar knew how to use radiation.  I don't have a reference handy but I've seen such claims in various kook books, usually following the old Ark of the Covenant and/or Emerald Tablet of Hermes Trimegistus as radioactive material/atomic reactor line of craziness.
