VESUVIANITE (IDOCRASE)
Jeffrey Mine, Asbestos, Quebec, Canada
From a find made circa 1989, this very nice specimen would make an
excellent addition to any collection specializing in double terminated
crystals, or single crystals. This double terminated crystal is also color
zoned! It has a light pink exterior, and a pale green center. The pale
green color zone runs down most of the length of the crystal, but can only
be seen clearly at one of the terminations – the termination shown at
the top, as the specimen is oriented in the photo at the left. Both
terminations are very sharp and shiny, and the prism faces are also sharp
and shiny, with some stepped growth evident. The crystal is slightly
tapered, i.e., slightly wider at the base, with no growth imperfections or
point of attachment. For background information on the Jeffrey Mine and
minerals found there, please refer to the "Mineralogical Record"
magazine, Vol. 10, No. 2 (March-April 1979), P. 69-80, however, pink
Vesuvianite crystals were not found at this locality until about 8-10
years after the article was written.
Specimen size: 2" long. The diameter varies from 3/8" X
3/8" at the top, to 1/2" X 1/2" at the base.

SZENICSITE with POWELLITE
Jardinera No. 1 Mine, Inca del Oro, north of
Copiapo, Atacama Province, Chile (type locale)
Szenicsite is a fairly recently described mineral species – see the
"Mineralogical Record" magazine, Jan-Feb 1994, P. 66
(advertisement and color photo), and P. 76 (abstract). Also see "Dana’s
New Mineralogy", P. 1003, and "New Minerals 1990-1994". P.
180. Szenicsite, a copper hydroxyl molybdate, has formed "torbernite
green" color bladed crystals and crystalline intergrowths, in a
fairly attractive grouping, with a small amount of rock matrix. The light
brown and pale green areas visible on the center and right side of the
specimen are small masses of secondary Powellite. In the center of the
specimen, the light brown platy hexagonal intergrowths are Powellite,
pseudo after Molybdenite crystals. The Powellite is fluorescent bright
yellow under SW UV only. The specimen has an original Aurora Mineral Corp.
label, which is Terry Szenics’ company label.
Size: 1 3/4" wide X 1 1/4" high X 1 1/8" thick

GOLD
Rosia Montana (Verespatak), Romania
Rosia Montana is probably the most famous of the European Gold localities.
Several fine color photographs of Gold specimens from this locality are
featured in the "Mineralogical Record" magazine, Vol. 13, No. 6
(Gold I issue), Nov-Dec 1982, P. 360, 36l, 364, 369, 372, and 373. The
text on P. 374 briefly describes the Rosia Montana locality and Gold
specimen habits found there. The Gold is always very bright, and was found
as crystals, leaves, wires, and dendritic aggregates. The specimen
pictured at the left is from the F. Marshall collection, and consists of a
very bright leaf of native Gold associated with a small amount of white
Quartz which is present along the top edge of the leaf, on the front of
the specimen. A thin layer of white Quartz also covers part of the back of
the specimen. Where the Gold is exposed on the back of the specimen, one
can see numerous tiny triangular markings (trigonal crystal faces) along
with several very tiny Sphalerite crystals. No rock matrix.
Specimen size: 3/4" tall X 1/2" wide X 1/8" thick
Order Item MI-1022 Price: $175.
SOLDNOTE: The following special Gold issues of the "Mineralogical
Record" are also available for purchase:
Gold I --- Vol. 13, No. 6, Nov-Dec 1982 Price: $45.
Gold II -- Vol. 18, No. 2, Jan-Feb 1987 Price: $12. |

STIBNITE
Bajuz (also sometimes spelled Baiuti, or Bejutz),
Maramures, Romania
A photograph of a large group of Stibnite crystals from this locality
appears in the "Mineralogical Record" magazine, March-April
1984, P. 117. This very aesthetic miniature size specimen consists of a
three-dimensional, fan-like grouping composed of more than 25 terminated
crystals, without matrix. The largest crystals are up to 3/4" and
7/8" in length. The specimen is temporarily mounted on a clear
plexiglass base for display, but can easily be removed if desired (water
soluble glue). F. Marshall collection.
Specimen size: 1 3/4" wide, 1 1/4" high, 3/4" thick

ELBAITE (Tourmaline) with LEPIDOLITE
Perdeneira Mine, State of Minas Gerais, Brazil
Four terminated, dark green Elbaite Tourmaline crystals, up to 1 3/8"
tall, form an intergrown group without matrix. The terminations have a
"frosted" luster, and the prism faces are sharp and striated.
Numerous other smaller Elbaite crystals, both terminated and
non-terminated, are present in the group. Tiny, very pale pink crystals of
Lepidolite are dotted over the front and back of the specimen. The
Lepidolite crystals have the appearance of "white pepper" as a
secondary deposition formed upon the prism faces of the Tourmaline
crystals, as shown in the accompanying photo. A few micro white Albite
crystals are also present on the back of the group. This specimen would
make a meaningful addition to any collection specializing in Tourmaline
group specimens, as it has complete locality information -- Brazilian
specimens with complete locality information are often difficult to find!
F. Marshall collection.
Specimen size: 1 3/8" wide, 1 1/4" tall, 1" thick.

ENARGITE
Leonard Mine, Butte, Silver Bow County, Montana
Two very good 1960’s vintage Enargite specimens are available here, both
from the F. Marshall collection. Item A. is a good "thumbnail"
size specimen, with the largest crystal measuring 3/8" tall. Item B.
is a very nice "miniature" size specimen with more than 20 very
sharp, metallic black terminated Enargite crystals of +/- 1/4" size.
An added feature for item B. is the association of three very pale blue
terminated, hexagonal Fluorapatite crystals of 2 to 4 mm size. Both
Enargite specimens are mounted on clear plexiglass bases for purpose of
display – these can easily be removed, if desired, as water soluble
Elmer’s glue was used.

CERUSSITE with BARITE 
Mibladen, Adeghoual, Morocco
This very attractive small miniature size specimen has a complete, double
terminated, euhedral, translucent pale smoky gray Cerussite crystal
perched upon a matrix of light orange to white bladed Barite crystals. The
Cerussite crystal measures 1" long, and 3/4" X 3/4" in
cross section, with very lustrous faces and complex form. The Cerussite is
fluorescent bright yellow-golden under both SW and LW UV. Phos: none. The
Barite is a vein section with multiple intergrown crystal blades on the
front of the specimen (light orange in color), grading to massive white on
the back of the vein. C. Yoder collection.
Specimen size: 1 3/8" wide, 1 1/8" tall, 3/4" thick
