December 9, 2019.    New Arrivals Page 1  has been updated with a mix of less expensive to somewhat more expensive mixed minerals.  I put a little bit of everything in this update, some self collected material as well as purchased specimens.  Many of the locations are not commonly seen, or relatively unknown.     Colorful assortment. 

November 21, 2019.    New Arrivals Page 4  has been updated with a suite of stibnite specimens from the White Caps mine, Nye county, Nevada.   When it was operating the White Caps mine produced the best stibnite specimens ever produced in the United States.  Spectacular specimens of brilliant, metallic crystals in pieces up to 30 or more pounds were recovered.  These are generally not available on the market, and it is very rare to even see any specimens from this locality offered for sale.  A half dozen years or so ago I was able to go underground and do a bit of collecting.  The mine was being evaluated for more production (it was primarily a gold mine) and the underground access was temporarily available.   The pieces I collected are not of the superb quality available when the mine was operating.  They are good representative location specimens though, and available exclusively on this site.   

November 18, 2019.    New Arrivals Page 2   has  been updated with a suite of molybdenite specimens, some with associated powellite?  I was fortunate enough to be able to go underground at the Pine Creek tungsten mine many years ago, just before the mine closed.  .  It gave me the opportunity to collect a nice suite of molybdenite specimens, which in some areas of the upper workings were quite abundant at the time.   I finally got around to cleaning and trimming these specimens for sale.  This update features specimens from what is called the exoskarn zone.  This is the part of the contact zone that was originally limestone, and now replaced with molybdenite, scheelite, andradite, epidote, quartz and chalcopyrite.  The specimens in this update do not have much if any scheelite.  They are from the molybdenite rich areas, which in places had veins of solid molybdenite up to a foot across.   There is some oxidation in places in these upper workings, where green copper staining from weathered chalcopyrite has taken place, and powellite has developed around the molybdenite, as well as rather rusty looking massive quartz.    I believe these to be the finest molybdenite specimens for crystal size in the lower 48 states.    Although not complete rosettes, some of these crystals measure up to 9 cm across...fairly huge for molybdenite.   Bright yellow fluorescing powellite is abundant on some pieces as nearly invisible cream to colorless thin coatings and replacements of the molybdenite and coating some of the quartz    It is not easily visible unless hit with short wave ultraviolet light, where it lights up with a bright yellow color.

 October 29, 2019  New Arrivals Page 3 has been updated with a suite of molybdenite specimens, some with associated powellite?.  I was fortunate enough to be able to go underground at the Pine Creek tungsten mine many years ago.  It gave me the opportunity to collect a nice suite of molybdenite specimens, which in some areas of the upper workings was quite abundant at the time.   I finally got around to cleaning and trimming these specimens for sale.  This first batch of specimens are from the endoskarn zone.  Endoskarn is the original granite that has been altered by hydrothermal fluids which changed the basic composition of the granite.  This endoskarn is represented by abundant hornblende crystals embedded in granular to massive grayish quartz and white, very fine grained feldspar.  Molybdenite in anhedral to euhedral crystals is present for a nice contrast.   Bright yellow fluorescing powellite is abundant on some pieces as nearly invisible cream to colorless thin coatings and replacements of the molybdenite and coating some of the quartz and feldspar.   It is not easily visible unless hit with short wave ultraviolet light, where it lights up with a bright yellow color.  The next update will feature specimens from the exoskarn zone, which is the limestone that has been replaced with andradite, epidote, chalcopyrite and molybdenite. 

 

  

 

    We have adjusted the site to contain more pages under General Stock.  There are now 25 General Stock Pages.   There are New Arrivals Pages 1, 2, 3, & 4, which are the same.    In General Stock there is General Stock page 1, "A thru Ay", General Stock page 2 is "Azurite", General Stock page 3 is "B", General Stock page 4 is "C", General Stock page 5 is "D", General Stock page 6 is "E", General Stock page 7 is "F and G", General Stock Page 8 is "H, I, J, K", General Stock page 9 is "L and M", General Stock page 10 is "N and O", General Stock page 11 is "P through Py", General Stock page 12 is "Pyromorphite", General Stock page 13 is "Q", General Stock page 14 is "R", General Stock page 15 is "S", General Stock page 16 is "T", General Stock page 17 is "U and V", General Stock page 18 is "W", General Stock page 19 is "X, Y, and Z", General Stock page 20 is the "Nevada" page, General Stock page 21 is "Thumbnail" size specimens at 40% off original price, General Stock Page 22 is the first "Sale Page", General Stock page 23 is the 2nd "Sale Page".  General Stock page 24 is the 3rd "Sale Page".   General Stock Page 25 is now dedicated  to specimens over $300.     General Stock Page 26 is a bit of a misnomer.  I'm reserving it for photos from my collection, photos of interesting field trips and finds, and the like.   More of an information/fun page.

  We are a mineral dealership located in Reno, Nevada.  We are ardent field collectors and have been dealing in and collecting minerals for many years.   You can see us in person every year at the following shows:   San Francisco show in August and the Tucson show in February. 

I have been a mineral collector since I was taken underground at the Clayton Silver mine in Idaho at the ripe old age of 9, by my grandfather, who worked there as a foreman.  My first look at the mine's working  face of solid sparkling galena had me hooked on minerals from that moment on.  Since then I went on to get my Masters' degree in Geology with a focus on economics and mineralogy.    My favorite mineral is pyromorphite.  I'm always on the lookout for pyromorphite specimens.  I am particularly interested in Canadian specimens.
