MMX96AN9: Octahedral crystals of Franklinite with very sharp crystal forms and with the dominant octahedron beveled by the dodecahedron. One of the crystals is clearly dominant and very aerial on a Calcite matrix. We emphasize that the crystal, in addition to being very aerial and complete, is practically free of damage, something really unusual in this type of specimen.
To all this we must add that the specimen comes from the prestigious collections of John Kolic and Chester Lemanski.

In addition, the crystals are covered by very unusual orange Sphalerite crystals (analyzed) which form globular groups.
The specimen undoubtedly owes its rarity to the fact that it is very old and comes from the collection of Pierre-Marie Guy, who was the one who acquired it from the miner Robert Guy.

The large cubes, with good transparency and a nice uniform green color, have inclusions and on some edges octahedral faces that can be distinguished from cleavages because they are somewhat rough and show crystal figures. Exceptional specimen from a historic mine.

MFR6AP3: One of the best, if not the best, Imayoshiite of very large size, coming from the 2021 finds that yielded the best known so far for the species. On a good size group of very lustrous twinned Sphalerite crystals several Calcite crystals with dominant scalenohedral forms have been precipitated and then were in turn covered almost entirely by whitish Tobermorite-Clinotobermorite crystals and, finally, a large quantity of Imayoshiite crystals of a pale cream color. Thanks to three "windows" in the Calcite crystals we can see the whole process of formation. This very "geological" specimen has been analyzed and we will send a copy of the analysis to the buyer.
To learn more about this species and the rest of the paragenesis discovered so far in this mine it is essential to read the article ‘Rare Borate Minerals from the Shijiangshan-Shalonggou Deposits, Hexigten Banner, Inner Mongolia, China', whose authors are César Menor-Salván, Berthold Ottens and Ed Richard, featured in Rocks & Minerals, September/October 2021, volume 96, number 5

The group is on matrix with lamellar Muscovite crystals, and small very lustrous water-clear crystals of Fluorapatite in the front, and larger crystals of pink Fluorapatite in the back, together with white rhombohedral Calcite crystals. An especially elegant specimen in which the perfection and the absence of damage to the crystals and their harmonious arrangement on the matrix make it aesthetically pleasing, something that does not normally occur in this species.
