Alphabetical List Tree DiagramDetailed Mineral List:
| ⓘ Acanthite Formula: Ag2S |
| ⓘ Analcime Formula: Na(AlSi2O6) · H2O Localities: Habit: Trapezohedra to 2.5cm in diameter Colour: reddish Description: When they are associated with good copper crystals they become objects to lust after. I am sure that the best of them would bring well over a thousand dollars but without the copper association these analcimes would probably not even make this list of notable localities. Also as rare pseudomorphs after feldspar(?).
