November 12, 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 was 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. 

October 17, 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.  Featured are a fine Milpillas azurite/malachite cabinet specimen, and a unique quartz combo from Minas Gerais.  Colorful assortment. 

August 20, 2019.    New Arrivals Page 4  has been updated with a suite of mixed minerals from around the world.  This update features superior quality minerals priced at $300 and more and most specimens are cabinet to large cabinet size specimens.  Featured are a fine Pingtouling mimetite, an excellent Milpillas azurite, a really nice Liufengshan azurite,  a great Vera Cruz amethyst, and a couple of superb epidotes from a one time limited find from Tormiq area of Pakistan; a juicy raspberry read liddicoatite from Madagascar, a fine Los Lamentos wulfenite, and several very good vanadinite/barite combos from Mibladen.   Great eye candy in this update.  

 

    We have adjusted the site to contain more pages under General Stock.  There are now 23 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.
