Argentinian Amethyst

Argentina it is not a well know mineralogical country. An Argentinean Quartz quarry's owners carried out work searching for fine Quartz specimens to sell on the mineral market. I have an excellent relationship with him, so I purchased the best of his production. For the moment they are finding huge, doubly terminated, and frequently sceptered Amethyst Quartz. The first generation is milky white Quartz, the second generation is a deep Amethyst colored Quartz. Most of the specimens are floaters and some of them are on matrix too. Size, form and phantom inclusions are very attractive and offer to the mineral world something new that in my opinion it will help to place Argentina on the collector's map.

Doubly terminated Quartz (variety amethyst)
 

EV16H2: Doubly terminated floater. The color is deeper at the terminations, whose luster is also more intense than in the other faces. The crystal grew on other small crystals of Quartz (amethyst)

SV3440ETM: A peculiar discovery from 2021 in the Austria Duvas Mine, where these rhodochrosites appeared in rosette shapes associated with Quartz and minor Sphalerite. Their striking resemblance to the rhodochrosites from Cavnic, Romania, is curious to the extent that at mineral shows, Romanian dealers seeking pieces for their home market sometimes get confused and believe that they are from their own country.
In any case, they are truly pretty, and this one, in addition, quite big.
