Acanthite (good thumbnail)

Item Description

A good thumbnail display specimen of sharp, well-formed modified grey cubic Acanthite from the famous Hongda silver mine in China. It has great form and displays beautifully as you can see in the photos. The largest crystal measures 1.7 cm. These specimens were all over the place about five years ago and have completely dried up now, so don't miss out on this one. Please note, sometimes these specimens are labeled as "Argentite" or pseudomorphs after Argentite, but this is not correct because Argentite cannot exist at our current atmospheric pressure below 177C, so all of these silver sulfide specimens are Acanthite.
