MT91AD9: Stalactitic growth with botryoidal forms at the narrow area and fluidal ones where it widens. A morphologic curiosity, unusual for the Capillitas mine.
Capillitas Mine, Andalgalá Department, Catamarca  Argentina (2015)

Specimen size: 6.4 × 4.2 × 4.2 cm = 2.52” × 1.65” × 1.65”

Rhodochrosite stalactite
 

CT52D6: As you can see in the photo this stalactite of Rhodochrosite has been polished at the bottom. In this case we feel that this helps one appreciate the beauty of its interior. Apart from the length, the fact that there are two stalactites, their great color and form means that we have decided to publish this specimen, even though it does not match our normal criteria for collectible specimens. It has a special quality that we think would make it of interest to anyone who collects minerals.

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.
