Hematite after GoethiteOne of the few specimens of this material that Ive encountered. This piece is essentially a pseudomorph of one iron oxide replacing another (i. e., Hematite and Goethite). This foliated group of good sized crystals is an excellent representation of a material that is rarely available on the market. My father acquired this piece from his Amazonite collecting partner, Clarence Coil in 1975. Ex. Clarence Coil collection Specimen# CO712B191

the crystal itself is virtually WATER CLEAR

As the name implies

which is likely to be caused by a micro amount of oxidized Cuprite on the surface of the specimen

Specimen# GEMXL71509

Specimen #PREH31113

very sharp

and these particular pieces are some of my favorite Rhodochrosite specimens from Colorado

These specimens are becoming increasingly difficult to find on the market today

The piece is a hydrothermally etched

Specimen# CO712B179

and is nearly 100% WATER-CLEAR with a vibrant pink-red interior color

lustrous bronze colored octahedron of the Microlite Group (most likely Fluornatromicrolite) is wedged between the Albite and Microcline on the reverse side of the specimen
