Samsonite
            from Samson mine, St Andreasberg dist., Harz, Lower Saxony, Germany
Special Info
EDS Confirmed

Short prismatic crystals to 8mm. There are numerous smaller from minute 1mm to the longest at about 8mm. Some deep internal red reflections can be seen. Backside contains some nice Pyrargyrite. Some possible Dyscrasite. Some Pyrite. EDS confirmed.

The second specimen are also from Andreasberg, which is the classical locality in which Samsonite is known for and is the type locality, named after the mine.  The crystals are all deeply striated with hints of red internal reflections typically seen in silver sulfosalts. The largest crystal is 7mm long but is not terminated. There is another 5mm crystal, which is nearly parallel to the largest crystal, but it is seperated by about 1mm at the base. The crystals merge together at the top giving the appearance that there is only one crystal, which is not the case. There is another 1mm stubby crystal seperate from the main crystals. As stated, Samsonite is extremely hard to obtain.
