PYROXMANGITE, CUMMINGTONITE
Conselheiro Lafaiette, State of Minas Gerais, Brazil

The Pyroxmangite from this locality has formed translucent-opaque, bright rose pink cleavages without rock matrix. Though no crystals are present, these are excellent examples of a rare manganese silicate seldom seen for sale, from a find made in Brazil during the past 8-10 years! X-ray analysis shows very small amounts of colorless to white veinlets of Cummingtonite are intergrown / associated with the Pyroxmangite on all specimens.

FLUORITE on smoky QUARTZ
Mont Blanc, Haute-Savoie, France
An intergrowth of more than 15 translucent, bright rose pink octahedral crystals of Fluorite have formed an inverted U shaped "crest" on top of a group of medium smoky gray color terminated Quartz crystals. The two largest octahedral Fluorite crystals measure 5/8" X 1/2", and 1/2" X 1/2" across, and there are several other 3/8" up to 1/2" size, bright rose pink octahedral crystals present in the group. No rock matrix. Jim Clark collection.
Specimen size: 1 1/4" tall X 1 1/2" wide X 1" thick at the base.

PYROMORPHITE
Kintore Opencut, Broken Hill, New South Wales, Australia
These "thumbnail" size specimens were collected about 6-7 years ago -- a fairly recent find, from a classic locality! The Kintore Opencut produced quite a number of very nice, lustrous, light brown Pyromorphite specimens, as reported in the "Mineralogical Record" magazine, May-June 1993, P. 227 (24:227). The specimens featured here were provided by Mike Newnham, mentioned in the "MR" write-up as the source for the "nice Bad Ems-like brown Pyromorphite crystal groups". All specimens are composed of intergrowths of sharp crystals with simple hexagonal form, with the prisms elongated and slightly barrel shaped in the center on some of the larger crystals. Item A. is a group of single terminated crystals with a very small amount of matrix. Items B. through D. are "floaters", i.e., they have no matrix or point of attachment, and the Pyromorphite crystals are double terminated. Item C. has a secondary deposition of smaller Pyromorphite crystals clustered around one end of the specimen, and item D. has a profuse deposition of secondary Pyromorphite crystals completely covering one of the terminations. Specimen sizes are given: length X width X thickness, in inches. Order item MI-049, A. through D.

TOPAZ
Mursinka District, Ural Mountains, USSR (Dana locale)
Water clear single crystal with sharp termination and prism faces, with a slight irregularity in the faces at the back of the crystal where it contacted another crystal, in the pocket. The crystal is a very pale aqua color, and has no matrix. Very good specimen for display of thumbnail size single crystals specimens, or gemstone crystals.
Specimen size: 1 1/8" tall X 5/8" wide X 1/2" thick.
