Among the most commented upon novelties at Tucson 2007 were Peruvian Rhodonites from the San Martín Mine. Although this mine was previously known for that species, more careful methods of extraction by the actual owners of the mine made it possible to obtain new samples of a high quality, especially if we consider their color, because previous Rhodonites were generally pinker than the best new ones, which are more red.
Our selection is based, precisely, on picking just the deep red specimens because we believe color is the most distinctive aspect, in terms of quality, of the Rhodonite.

From the not so well known Santa Rita Mine come these Sphalerites of clear color and sharp crystals, well placed on a matrix covered by concretions of non pink Rhodochrosite. This mine also produces some high quality Galena.

One of the major novelties in the 2001 Ste. Marie / Denver Shows was the new wire Silver from Uchucchacua, Lima, Peru. They were found at the start of this year and their quality and beauty is comparable to the best finds from the old famous localities such as Kongsberg, with maybe better luster on the Silver crystals.
On some cases it is better to take care. For this reason we took our time to analyze the matrix of this new specimens and for to check carefully each specimen to be sure that nothing was faked. Analysis proved that the dark brownish matrix of these specimens is a natural amorphous Silicate of Manganese and that the white-yellowish crystals are Rhodochrosite. As usual, we will send copy of this analysis to the buyers of the specimens.

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.
