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.

TFF27AN4: Extensive group of Kësterite crystals with very sharp crystal forms and a yellowish brown color due to coatings of Mushistonite. 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.
Mount Xuebaoding, Pingwu, Mianyang Prefecture, Sichuan Province  China

Specimen size: 7.8 × 6.9 × 4.1 cm = 3.07” × 2.72” × 1.61”

Main crystal size: 0.9 × 0.8 cm = 0.35” × 0.31”

ER53AM5: Twinned Cassiterite crystals, on matrix, with Quartz crystals. The crystals have very well defined faces and edges, they are transparent to translucent and dark brown in color. The luster and size of the crystal are extraordinary. One of the best pieces found in this locality.
Amo deposit, Ximeng, Pu'er Prefecture, Yunnan Province  China (2002)

Specimen size: 11.8 × 9.7 × 7.5 cm = 4.65” × 3.82” × 2.95”

Main crystal size: 4.7 × 4.7 cm = 1.85” × 1.85”

MD89AK0: Group of very sharp Babingtonite crystals, some of them doubly terminated, with very well defined faces and edges, very bright and on a matrix of transparent Quartz crystals. Also there are groups of green spheroidal Prehnite crystals and white trapezohedral Analcime crystals. Specimens of such quality are already classics for global mineralogy.
Babingtonite occurrences, Qiaojia, Zhaotong Prefecture, Yunnan Province  China (2010)

Specimen size: 14.7 × 12.5 × 5.9 cm = 5.79” × 4.92” × 2.32”

Main crystal size: 3 × 1.8 cm = 1.18” × 0.71”

ER94AM1: A large doubly terminated scepter and stepped crystal of Diaspore with polycrystalline terminations, transparent, lustrous, yellow with green reflections and partially covered in some areas by leafy growths of Margarite. A very remarkable specimen both for its size and color and for its perfection.
The specimen has been reviewed, photographed and published in the Russian magazine ‘Mineral Observer’ on page 86 in the volume 26/2021, number 1
Ilbir Mountain, Pinarcik, Milâs District, Muğla Province, Aegean Region  Turkey (2020)

Specimen size: 14.9 × 3.6 × 1.7 cm = 5.87” × 1.42” × 0.67”

ERJ92AN5: Group of Fluorite crystals, basically octahedral in habit but also with smooth cube faces along with the octahedral faces (and other crystallographic forms) incorporating very extensive and easily visible fine polycrystalline growths. The crystals are large, transparent, with very bright luster and an intense and uniform pink color, on a matrix of very sharp lamellar crystals of Muscovite. Exceptional.
