P-095 Phlogopite $50
Ladjuar Medam, Sar-e Sang, Koksha Valley, Badakhshan, Afghanistan
4.5 x 5.4 x 4.1 cm
A textbook-perfect and very clear example of Phlogopite on matrix. This is a rather large crystal for this location. The Phlogopite from Ladjuar is well-known for its excellent yellow fluorescence. These specimens came out around 11-12 years ago and are considered to be some of the best quality crystals for the species.
on Gypsum $65
Eureka County, NV
5.7 x 4.6 x 3.0 cm.
Here we have an old-timer Nevada Sulphur specimen with well-defined, translucent-to-transparent crystals to just under 1 cm. on a matrix of white Gypsum. While the specimens from Steamboat Springs, just south of Reno get all the accolades when it comes to Nevada Sulphur crystals, these specimens from Eureka County are just as good. Examples of this material are nearly impossible to come by, even for those of us that Live in northern Nevada.
C-255 Corundum variety Sapphire $160
Bawmar, Kyatpyin North, Mogok Township, Pyin-Oo-Lwin District, Mandalay Region, Burma
5.3 x 4 x 2.7 cm
Here we have an alluvial Sapphire crystal from one of Asia's more prolific gem producers. This crystal still has some of its matrix attached. This Sapphire has a medium-yellow color that is stained red by iron that has leached from the piece of the crystal's host rock that is still attached. Despite being river-tumbled, this Sapphire shows good form. This specimen would make a colorful addition to any collector's mineral cabinet.
B-210 Barite on Fluorite $200
Xiefang Mine, Ruijin County, Ganzhou Prefecture, Jiangxi Province, China
8.5 x 6.8 x 5 cm
This specimen features blocky to tabular, honey-brown Barite crystals to 1.6 are studded on a matrix of green-colored Fluorite crystals. The Fluorite is contacted on the back, which I think is better than being sawn like many of these were. This specimen is from a find in China about 10-12 years ago. Sadly, very few of these colorful specimens came out, and it looks like no more will.
F-233 Adularia & Hematite $60
Zagi Mountain, Hameed Abad Kafoor Dheri, Peshawar, Khyber Pakhtunkhwa, Pakistan
8.5 x 5.2 x 3.5 cm.

Ojuela Mine, Mapimí, Municipio de Mapimí, Durango, Mexico
6.5 x 3.9 x 1.8 cm
This specimen features numerous gemmy crystals of the mineral Adamite on a gossan matrix. The clusters of Adamite on this specimen are bright and lustrous too. Also this specimen is extremely fluorescent. The Ojuela Mine has produced many of the worlds best Adamite specimens.
S-160 Strontianite on Fluorite $100
Minerva #1 Mine, Ozark-Mahoning Group, Cave-in-Rock, Hardin County, IL
9.9 x 7 x 4.1 cm
This specimen features needle-like sprays of white Strontianite crystals cascading down a matrix of translucent, yellow-hued Fluorite crystals. Strontianite is a rare carbonate mineral (strontium carbonate) and one of only a handful of known strontium minerals. Crystals are rarer than the massive forms.
P-091 Pinolite $45
Magnesite Deposit, Sunk, Hohentauern, Niedere Tauern, Styria, Austria
8.6 x 6.2 x 1.3 cm
Here we have an unusual specimen of two carbonate minerals, known as Pinolite, from Styria, Austria. Named for the white Magnesite crystals resembling pine kernels (hence the name), encased in a graphite-grey to almost black matrix of Dolomite.
H-072 Hematite $75
Knollengrube, Bad Lauterberg, Harz, Lower Saxony, Germany
8 x 4.1 x 1.4 cm.
A fine example of kidney-ore from a classic locality. The luster of this attractive specimen is very high. This ancient mine was worked for both copper and iron that was found in the Barite veins until it was abandoned in 1913. Examples of this material are rarely available to collectors anymore.
P-076 Plumbogummite & Pyromorphite $275
Yangshuo Mine, Guilin Prefecture, Guangxi Zhuang Region, China
4.7 x 4.6 x 2.8 cm.
This specimen consists of a slightly divergent cluster of Pyromorphite crystals to 4.5 cm. in length that have been mostly replaced by the sky blue lead phosphate mineral Plumbogummite. Most of the crystals exhibit hopper growth at their terminations. Basal portions of the crystals still have remnants of the original Pyromorphite. A great example from the pocket with medium-sized pyromorphite crystals for this find, which would be huge by any other standard.
on Calcite $60
Stoneco Lime City Quarry, Lime City, Wood County, Ohio
8.6 x 5 x 5.1 cm.
An excellent, well crystallized example of Celestite from a noted Ohio locality. This specimen features well-formed crystals of Celestite measuring up to 1.5 centimeters. The yellow-colored Calcite on which these lustrous Celestite crystals sit upon makes for a nice contrast of colors. This specimen dates back to the 1970's according to the collection label that came with the specimen.
W-024 Witherite & Barite $165
Nentsberry Haggs Mine, Alston Moor, Cumbria, United Kingdom
10.6 x 9 x 6.1cm.
The region of England known as Cumbria has a rich mining history that goes all the way back to the time of the Roman occupation and, for some time, been regarded as a mineral collector's paradise, being a prolific producer of more than 300 different species. This chunky specimen of Witherite is larger than most from this mine. The crystal is complete and exhibits a white coating which is an alteration to the mineral Barite. This specimen was recovered in the area of the mine known as Admirality Flats, more specifically the High Raise Second Sun Vein.
A-114 Aragonite $70
Bristol Mine, Bristol and Jackrabbit Districts, Lincoln County, NV
12.3 x 11.9 x 7.9 cm
This very three-dimensional formation of Aragonite is from a defunct silver mine. These specimens are formed by ground water deposition inside the underground mine.
C-254 Corundum variety Sapphire $165
Wellawaya, Moneragala District, Uva Province, Sri Lanka
8.6 x 6 x 2.3 cm
This specimen is something you is almost never seen from Sri Lanka, a Sapphire crystal in matrix. Matrix specimens are all but unheard of. The main Sapphire crystal on this specimen is double-terminated and has a reddish-purple hue. The other crystals in the matrix of this specimen are lighter in color with some being translucent. Sri Lanka has long been known for its seemingly endless supply of Sapphires. Gemstone mining in Sri Lanka is from secondary deposits. The gravels yield Sapphire, Ruby and many other gemstones. Sri Lanka’s gem-bearing gravels, called illam, are some of the richest in the world. The island was blessed with geological conditions that provide an ideal blend of chemistry, heat, pressure, time for gem crystals to grow, and weathering for the gem crystals to be deposited and concentrated in gravels.
B-220 Barite $75
Baia Sprie Mine, Baia Sprie, Maramures County, Romania
8.1 x 5 x 4.5 cm
Here we have a cluster of thin pale, blue-grey Barite crystals on matrix. This three-dimensional specimen features fans of Barite crystals measuring up to 2.1 cm in size. These blue Barite specimens are some of the most desirable of the species from this location.
H-088 Halite $60
Stassfurt, Stassfurt Potash Deposit, Saxony-Anhalt, Germany
8.3 x 8.4 6.7 cm
A large and relatively complete crystal of blue-colored Halite from a very old, classic locale, showing sharp phantoms. Since Halite cleaves easily, it is hard to say if all faces are present, but I think most faces certainly are legitimate and show the slight imperfections you would expect of natural cubic faces.
variety Ruby $135
John Saul Mine, Tsavo West, Voi, Taita-Taveta County, Kenya
3.6 x 2.2 x 1.8 cm
A well-formed and double-terminated crystal of Ruby from what many consider to be the most important Corundum locality in Kenya. As with all John Saul rubies, this specimen fluoresces a deep cherry red under long wave ultraviolet light. I think that when I photographed this specimen, the lights I used made it fluoresce a little.
G-120 Goethite $45
Hall Molybdenum Mine, San Antone District, San Antonio Mts., Nye County, NV
12.8 x 9.4 x 2.4 cm.
Goethite with mineral staining giving the specimen an iridescent look. Goethite specimens are usually not so colorful. This specimen was acquired from Dawn Minette who along with husband Jim collected this material.

Julcani District, Angaraes Province, Huancavelica Department, Peru
11.2 x 10.1 x 4.2 cm.
A classic and fairly hard-to-find siderite specimen from the famous Julcani District in Peru. This attractive specimen hosts sharp, well-formed, rhombic Siderite crystals with a pleasing, silky lustre on a matrix of massive Pyrite. This specimen also features nearly a dozen squat crystals of colorless Apatite making for an unusual association. Also found on this specimen are numerous small crystals of Chalcopyrite.
H-080 Hemimorphite with Smithsonite $30
Dauntless Mine, Robinson District, White Pine County, NV
6.5 x 5.6 x 2.9 cm
Another mineral that you don't usually associate with Nevada is Hemimorphite. This specimen features Hemimorphite crystals up to 1.3 cm in size in a vug lined with sparkly crystals of Smithsonite.
P-087 Prehnite $40
Luck Stone Quarry, Bealeton, Fauquier County, VA
6.7 x 5.5 x 5.6 cm
This lustrous specimen of mint-green-colored Prehnite features crystals up to 1 cm in size. Mineral specimens of any species are extremely rare from this obscure Virginia quarry. In fact, mindat.org only has 2 examples of Prehnite from this location.
V-023 Vanadinite $35
ACF Mine, Mibladen Mining District, Midelt Province, Drâa-Tafilalet Region, Morocco
5.7 x 3.1 x 1.7 cm.
A plate of translucent, richly-colored, red Vanadinite crystals. The largest crystal on this specimen measures 1.3 centimeters. A slightly better than average Vanadinite specimen from Morocco.
P-079 Pyrite $50
Rensselaer Quarry, Pleasant Ridge, Jasper County, Indiana
4.3 x 4.5 x 2.6 cm.
A great old Indiana Pyrite, with sharp, well-formed, modified pyritohedrons perched very attractively on a micro crystal-covered matrix. Though there are plenty of Peruvian and Spanish pyrites around, you don't see many of these Indiana ones around. The Rensselaer Quarry had a reputation as an extremely challenging quarry to extract specimens from. Many of the specimens from here were coated in thick hydrocarbons. This location has been flooded and closed for some time now.
S-138 Silver $95
Hellens-Eplett Mine, Cobalt Area, Timiskaming District, Ontario, Canada
7.1 x 5.6 x2.4 cm.
A good example of "leaf" silver from the renowned Cobalt area of Canada. This specimen features a rather large, for the location, sheet of Silver covering and rising above a meta-sediment matrix. Metasedimentary rocks are a class of metamorphic rocks where the original rock (protolith) was sedimentary. You don't see to many Silver specimens from this mine as it was only active from 1983 to 1988.
C-240 Cookeite with Quartz $35
Stand on Your Head #1 Mine, Bland, Saline County, AR
5.5 x 4.5 x 4.5 cm.
Here we have a specimen that is covered with green and blue-green spherules of translucent Cookeite on a matrix accented by sparkly, tiny Quartz crystals. Cookeite is an uncommon Chlorite group species. These specimens were dug by Jimmy and Hisami Mc Neil in the 1980's. I acquired a small lot of Cookeite & Quartz specimens from Hisami at the 2015 Kyoto show, this was the only matrix piece of the lot.
G-087 Galena and Chalcopyrite $60
Joplin Field, Tri-State District, Jasper County, Missouri
5.5 x 5 x 4.5 cm.
This is an old Tri-State Galena specimen that is truly amazing to look at, in that its surface is completely covered with small, flat-topped epitaxial Galena crystals resulting from a second generation of growth. The main crystal is complete, with the back side being L-shaped where it was wrapped around the matrix rock. The Galena also has many tiny, golden Chalcopyrite crystals, which add to the specimens attractiveness.
and Sodalite $45
Poudrette Quarry, Mont Saint-Hilaire, Québec, Canada
7 x 6 x 2.5 cm.
A specimen of many highly fluorescent (bright orange under LWUV) Sodalite crystals, several of which are very well-formed. This specimen features a vug of many crystals of the rare mineral Dawsonite up to 1 mm. The orange arrow indicates where the colorless Dawsonite crystals are located, several of which can be seen protruding from the vug in the photograph on the right. This specimen also features a cluster of three Analcime crystals that measure 4 x 5 mm. on its upper right corner.
A-108 Apophyllite on Stilbite $35
Momin Akhada, Rahuri, Ahmadnagar District, Maharashtra, India
6.8 4.3 x 3 cm.
This specimen features a gemmy, radial spray of glassy, green-hued Fluorapophyllite crystals perched on a matrix of pale salmon-colored Stilbite crystals. These specimens were recovered during digging of several wells and are unique to this area.
P-070 Pyromorphite $40
Huari-Huari Mine, Seranía Huarihuari, Potosí Department, Bolivia
7 x 6.4 x 3 cm.
On a worldwide scale, these Pyromorphite specimens from Boilvia are not the best, but for the location, they are quite interesting and unique. This material is something that is very rarely offered on the open market. This specimen has many fine, sharp and somewhat lustrous, prismatic, green and yellow crystals of Pyromorphite sitting atop an oxidized matrix. These are very well formed crystals and are not skeletal or hoppered as is often the case with Pyromorphites from other locations. This specimen was collected in May of 2009.
P-072 Pyrite $65
Rio Marina, Elba Island, Livorno Province, Italy
7.2 x 6.7 x 3.9 cm.
The mineral wealth of Elba has been exploited since Etruscan times. It is a small wonder that there is anything left these days. No significant finds of Pyrite have been made here since the 1970's. The iron mines of Elba, most of which are long closed, were choice collecting localities for mineral enthusiasts, as early as the beginning of the 19th century. The pyrite specimens, such as this one, were especially prized. This brassy-colored specimen features many inter grown pyritohedrons up to 2.5 centimeters. This specimen is contacted on the lower sides but presents well and is not a detraction from the overall looks of the specimen. Ex. Howard Belsky collection.
Calcite and Pectolite $175
Poudrette Quarry, Mont Saint-Hilaire, Québec, Canada
8.5 x 7.5 x 5.4 cm.
A matrix specimen consisting of two 3-centimeter rhombohedral Siderite crystals surrounded by several smaller crystals, accented with clusters of grayish Calcite crystals and sprays of white Pectolite crystals. One of the larger siderite crystals has trivial wear on its corner, which in my opinion does not detract from the overall appearance of this specimen. The Calcite on this mineral specimen fluoresces red under shortwave ultraviolet illumination.
S-064 Sphalerite with Calcite $50
Naica, Munincipio de Saucillo, Chihuahua, Mexico
6.5 x 4.5 x 3 cm.
A very lustrous combination of Sphalerite and Galena crystals with tiny clusters of Calcite to give it a little extra pizzazz.
