Fluorescent Mineral Specimens Under Shortwave and Longwave Ultraviolet Light

Polman Minerals
Fine Fluorescent Mineral Specimens
and Ultraviolet Lamps

Welcome to the Polman Mineral Reverse Auction!

 

 

Here is how it works:

 

 

 

Specimens listed on this page will have a starting price and a starting date.  If you like the specimen, you may buy it outright at the starting price listed, or wait as the auction progresses.  Remember, it is first come first served, so if you want the specimen, you have to email or call immediately.

Periodically (it could be any number of days), we will reduce the price of that specimen.  The new price and date will be listed beneath the starting price.  Even if you are on the Polman Minerals email list, you will not be notified of this reduction.  The amount of reduction will be totally arbitrary.  As the price gets lower and lower, more and more people will want the specimen.  Once it reaches a price that you are willing to pay for the specimen, email immediately and purchase it!  Once a specimen has been purchased, it will be marked as sold.

The strategy for a reverse auction is to find a specimen you would like to own, and watch the auction page constantly.  We suggest you bookmark the auction page, and check it out at least daily.  Remember, there could be many other people watching the same specimen.  Only emails or calls made after the new price is posted will qualify.  There is no pre-bidding (in other words, no emails saying you will purchase the specimen when it reaches a certain price).

We guarantee quality specimens will be posted on this page, and the price will be lowered and lowered until they are sold (regardless of the price)!  A reverse auction is great way to get quality specimens cheaply, and can be a lot of fun in the process. As always, the customer is responsible for shipping and insurance costs.  Let us know if you have any questions or comments about our new Reverse Auction page.

 

 

Let the fun begin!!

Name: Tremolite, Caliche
Location: Sunset South Mine, Harquahala Mountains, Maricopa County, Arizona.
Size: 6 x 5 x 3-inches
Notes:
A very rich specimen of radiating tremolite with caliche.  The fluorescent response of the tremolite is slightly bluish white, but not quite as blue as the photograph indicates.  The caliche present fluoresces both orange and green is some areas.  This specimen would make a nice addition to a comprehensive Arizona collection.

Name: Opal
Location: Peacock Mine, Virgin Valley, Nevada.
Size: 3 x 2 x 1.5-inches
Notes:
This type opal has been labeled in the past as either semi-opal, common opal or opalite.  I believe now the appropriate term being used is just opal.  This specimen has a neat little shadow effect caused by different intensity of the luminescence.  Some people confuse this material with slag glass, but this opal is found as a seam within a chalk bed at the Peacock Mine in Nevada.  A trace of uranium is usually found in this type of opal, and is the activator responsible for the bright green response under shortwave ultraviolet light.

Name: Fluorite, Calcite
Location: Pure Potential Mine, La Paz County, Arizona.
Size: 6 x 4.5 x 3-inches
Notes: H
ere is a beautiful display size specimen of fluorite and calcite that I collected down in the Pure Potential Mine when it was in operation.  This means that the specimen is mine run, and not dump material.  The specimen will fluoresce under shortwave and longwave ultraviolet, but midrange provides the best response.  Specimens from this mine are some of the best midrange specimens available.  With the fluorite fluorescing purple and the calcite red, this color combination puts the colors on each end of the spectrum.  The human eye has a slight problem with the contrast created by colors this far apart on the spectrum, thus giving this material a sort of “eerie” glow to it.  Some of my favorite specimens in my own collection come from this mine.  This specimen was split along a vein of fluorite, showing just some spots of calcite sticking through.

Name: Sphalerite
Location: Horn Silver Mine, San Francisco Mountains, Beaver County, Utah.
Size: 3 x 2.5 x 2-inches
Notes:
Here is a specimen of yellow/orange fluorescing sphalerite from the famous Horn Silver Mine in Utah.  This specimen also contains a vein of red fluorescing calcite in the front, and some blotches of red fluorescing calcite on the back.  Calcite was not common in the material that was collected from this mine.  This mine is known for producing fluorescent sphalerite in various colors, ranging from orange, yellow/orange, peach, salmon, teal, sky blue, pink, green, tan and lavender.  In some cases, all the colors mentioned can be seen in one specimen!  This specimen is mostly the fine grain type, with mostly only yellow/orange fluorescing sphalerite.  All the sphalerite, no matter what the fluorescent color, is highly phosphorescent after exposure to longwave ultraviolet light.  The sphalerite is also highly triboluminescent as well.  In some cases, light can be generated by just scratching the specimens with a finger nail!  The sphalerite is also highly fluorescent and phosphorescent using the 405nm lasers that are now for sale on my website.

The history of both the mine and the recovery of these amazing sphalerite specimens is extremely interesting.  If you would like to know more about both, there is a discussion posted on the Horn Silver Mine Showcase page of this website.

Name: Calcite
Location: Gopher Valley Quarry, Yamhill County, Oregon.
Size: 5 x 3.5 x 3-inches
Notes:
These butterscotch colored calcite crystals came to market in approximately 1995 at the Tucson Gem and Mineral show.  Those of you who were at the show may remember a room in the Executive Inn which had many specimens from this find.  Other calcite specimens found from this quarry were the drusy variety and the translucent variety (I have exceptional specimens of each type for sale).  After this show, I purchased a large quantity of this material from the collector.  I have not seen any new material come from this quarry since, so it may be closed to collecting.  This specimen has some nice butterscotch crystals on the right side.  The calcite appears to be fluorescing in three shades of creamy white to brown.  The calcite will fluoresce under shortwave, midrange and longwave ultraviolet, with longwave providing the best response.

Location: Arnold Open Pit, Balmat, New York.
Size: 6 x 3.5 x 2.5-inches
Notes:
Here is an interesting specimen from the Arnold Open Pit in New York.  The specimen consists of a pastel orange fluorescing tremolite, a pastel reddish orange fluorescing anthophyllite and a fluorescent creamy yellow talc.  The specimens of tremolite and anthophyllite from this Balmat locality seem to be much more pastel in nature than the deeper orange and red fluorescing tremolite and anthophyllite from other nearby localities.

Name: Wollastonite, Aragonite?
Location: White Knob Quarry, Lucerne Valley, San Bernardino County, California.
Size: 4 x 4 x 2-inches
Notes:
Here is a nice two color specimen from the White Knob Quarry in California.  The specimen contains a medium yellow fluorescing wollastonite, with a small amount of a beautiful purple/blue aragonite?  Several years back I had this fluorescing purple/blue material analyzed twice, at two different places.  The analysis in both cases came back wollastonite.  However, this purple fluorescing material is usually found as coatings, and I strongly believe that each sample was contaminated with the wollastonite found beneath.  The material does react to HCl, and the consensus is that it may be aragonite.  Until someone makes an analytic confirmation of this, I will continue to use the question mark.  When the manganese content is just right, the wollastonite from this quarry can be quite bright.

Name: Caliche, Powellite, Scheelite
Location: Princess Pat Mine, Near Adalanto, California
Size: 3.5 x 3 x 2.5-inches
Notes:
Here is a nice three color specimen from the Princess Pat Mine in California.  The specimen consists of orange fluorescing caliche along with creamy yellow fluorescing powellite and spots of sky blue fluorescing scheelite.   Caliche, being a secondary coating of CaCO3, is very common in the desert southwest.  Occasionally caliche will fluoresce green (due to a trace of uranium), or orange (not sure if the activator for orange fluorescing caliche has been determined).  Although the photograph appears to indicate that the powellite is on the left side of the face and the caliche on the right side, the two are really divided by an angle in the rock.  In other words, the front face is not a flat face, but was photographed on an angle.  You can see this better in the white light photograph.

Notes:
Here is a specimen of ulexite from California.  Most people know this mineral as “TV Stone”.  When specimens of ulexite are cut on both ends, you can actually place the specimen on anything written on paper, and read the writing through the crystal!!  I checked this specimen and could not read through it, but could easily see light passing through it.  The ulexite will fluoresce bright white under shortwave, and bright creamy yellow under longwave and midrange.  Ulexite is also phosphorescent as well.

Name: Diopside, Fluor-edenite
Location: Rhein Property, Amity, Town of Warwick, Orange County, New York.
Size: 4 x 3 x 2.5-inches
Notes:
Here is a two color specimen consisting of fluorescent sky blue diopside, with the rarer mineral fluoro-edenite, which fluoresces a creamy yellow.  The fluoro-edenite did not photograph well in this specimen, but it is located more or less beneath the diopside.  There is a lot more diopside than fluoro-edenite in this specimen, hence the lower starting price. 

This material was recently discovered (a few years ago) on the Rhein Property in New York State.  The specimens were found within the Franklin Marble, which trends northward from the New Jersey Highlands into the state of New York.  

Once this find was discovered, several samples were sent for analysis.  The conclusion was that the mineral was in fact fluoro-edenite, with fluorescent blue diopside also associated with it.  I have heard that some specimens that fluoresced blue were also identified as fluoro-edenite, but at this time my guess is that there was some closely associated diopside on the specimen.  Fluoro-edenite is in the amphibole group of minerals.  The chemical formula for fluoro-edenite is NaCa2Mg5(AlSi7O22)(F,OH)2.

Name: Willemite, Calcite, Fluorite
Location: Reymert Mine, Pinal County, Arizona 
Size: 4 x 4.5 x 2.5-inches
Notes:
Here is a nice three color specimen containing fluorescing green willemite, fluorescent red calcite and fluorescent purple fluorite (looks more blue than purple in photographs).  The specimen is from the Reymert Mine in Arizona.  Although not quite as bright as similar material from the “3-Color” Mine in Arizona, it is still quite vivid in its response.  The willemite is phosphorescent in this specimen.  The Reymert Mine started operations again in 2002, and has since been closed to any collecting.  About 5 years ago I was given a special invitation to collect there, and was able to obtain some very nice specimens.  I will have more of this material for sale in the future.

Name: Hyalite Opal
Location: Zacatecas, Mexico.
Size: 3.5 x 3 x 2-inches
Notes:
Here is a specimen of the very interesting daylight fluorescing hyalite opal from Mexico.  The find was discovered a few years ago, and has recently been mined out.  Under incandescent lighting, this hyalite is the typical clear color.  However, when exposed to outside lighting, the opal will begin to change color to green, as it begins to fluoresce from the scattered UV light in daylight.  Another interesting characteristic of this hyalite is that it fluoresces best when exposed to violet light in the 420nm range.  It will, of course, fluoresce very brightly under all three wavelengths of ultraviolet light.  This particular specimen shows a very glassy luster, with the opal looking as if it were wet.

With sales of these specimens from my Worldwide Showcase, I have been including a free 405nm laser.  This hyalite opal will EXPLODE with bright green fluorescence when exposed to this laser!  For the Reverse Auction, I will provide the laser free if the specimen is purchased on the first day of the RA.  Otherwise, the laser’s are available for sale at the price of $10.00 each.

Notes:
Here is a nice little two color “starry night” specimen of both powellite and scheelite.  The ID of the two minerals is just based on a visual inspection of the fluorescent response, with the creamy yellow assumed to be powellite, and the blue scheelite.  The specimen also contains non-fluorescent andradite and epidote.  The piece is from a locality in California that I am not familiar with, and could be another plus for California collectors.

Name: Magnesite, Chalcedony
Location: Near Bagdad, Arizona.
Size: 5.5 x 3 x 2-inches
Notes:
Here is a specimen that I collected recently from a new find in Arizona.  Under midrange ultraviolet, the specimen contains a creamy white fluorescing magnesite, with veins of green fluorescing chalcedony.  Under shortwave ultraviolet light, the magnesite fluoresces a more bluish white, and the chalcedony can fluoresce in three shades of green.  I photographed these specimens under midrange ultraviolet so my camera would not over emphasize the blue.  However, the specimens are much more aesthetic under shortwave ultraviolet light.  The magnesite is also phosphorescent.

Name: Caliche
Location: Daisy Fluorspar Mine, Nye County, Nevada.
Size: 4 x 2 x 1.75-inches
Notes:
Caliche, being a secondary coating of CaCO3, is very common in the desert southwest.  Occasionally caliche will fluoresce green (due to a trace of uranium), or orange (not sure if the activator for orange fluorescing caliche has been determined).  Sometimes the fluorescent response can be very bright and showy.  This specimen has very good coverage, and is from a relatively obscure locality in Nevada.

Location: Gopher Valley Quarry, Yamhill County, Oregon.
Size: 3.5 x 3 x 1.5-inches
Notes:
These butterscotch colored calcite crystals came to market in approximately 1995 at the Tucson Gem and Mineral show.  Those of you who were at the show may remember a room in the Executive Inn which had many specimens from this find.  Calcite specimens found from this quarry were the drusy variety, the translucent variety and the larger butterscotch colored crystals.  After this show, I purchased a large quantity of this material from the collector.  I have not seen any new material come from this quarry since, so it may be closed to collecting.  This specimen is a nice representative specimen of the drusy variety.  The calcite will fluoresce under shortwave, midrange and longwave ultraviolet, with longwave providing the best response.

Name: Wollastonite
Location: Fengjiashan Mine, Edong Mining District, Hubei Province, China.
Size: 4 x 3 x 2.5-inches
Notes:
This specimen contains solid white bladed crystals of wollastonite.  Under shortwave and longwave ultraviolet, the wollastonite fluoresces a medium yellow (with varying intensities) as well as patches of lavender.  The medium yellow fluorescence is caused by a manganese activator, with lead as a co-activator.  Under midrange ultraviolet, the specimen exhibits a great color change. Under midrange ultraviolet, the wollastonite fluoresces a pinkish lavender color, with some zones of purple.  It is most likely a rare earth activator that causes this midrange color response.

Name: Wollastonite, Calcite
Location: Sterling Hill Mine, Ogdensburg, New Jersey.
Size: 4 x 2.5 x 1-inches
Notes:
Here is a specimen of yellow fluorescing wollastonite in a matrix of medium fluorescing red calcite.  The specimen is from the world famous Sterling Hill Mine in New Jersey.  This particular find contained calcite that was not as bright as in other areas of the mine.  The fluorescent response is more of a medium red rather than the bright red that people are used to seeing from the Sterling Hill Mine.  My guess is that the manganese content is not optimum for the bright red response.  The specimen still has an aesthetic quality to it, with the bright yellow wollastonite contrasting with the medium red calcite.  This material was collected after the mine was shut down in 1985, and prior to the mine flooding.

Notes:
Here is a nice specimen of exsolution willemite and calcite.   Exsolution is a scientific term used for specimens where the willemite is found in very thin sheets or lamellae within a mineral called tephroite.   At high temperatures (during metamorphism) the tephroite was able to accommodate a fair amount of zinc.  As the temperature cooled, the zinc was no longer compatible in the crystal structure, and the willemite solidified out of solution, forming thin layers within the tephroite.  Along with the green fluorescent willemite is some surrounding red fluorescent calcite.  The specimen is from the world famous Sterling Hill Mine in New Jersey.

Name: Idrialite
Location: Eureka Mine, Sonma County, California.
Size: 3 x 1.5 x .75-inches
Notes:
Here is a really nice multi-colored idrialite specimen from the Eureka Mine in California.  The specimen is sawcut on one face (front) and natural on the other (back).  Idrialite is a rare hydrocarbon mineral with the chemical formula C22H14.  The mineral was first discovered in 1832 at the Idria Mine in Slovenia.  Idrialite and curtisite were once thought to be the same mineral. However, it was later determined that they are both complex minerals, with different chemical compositions.  In fact, idrialite is composed of eight distinct hydrocarbons that have crystallized together, and lacks a singular ideal composition.  Mindat has idrialite as “possibly a complex mixture of polycyclic aromatic hydrocarbons.”  Despite this, it is still listed as a valid mineral species, whereas curtisite is not.   Idrialite can range in fluorescing colors from creamy yellow to bluish green.  This specimen also fluoresces in a deep tan and creamy orange as well.

Notes:
This is a specimen of “crazy” calcite from the famous Franklin Mine in New Jersey.  Until a relatively recent find of “crazy” calcite at the Sterling Hill Mine in the 1990’s, most of the “crazy” calcite came from the Franklin Mine.  When first discovered at Franklin, it was believed that the material consisted of calcite only, with different quantities of manganese as an activator, hence the term “crazy” calcite.  It was later discovered that the mineral fluorescing crimson red was dolomite and not calcite.  The specimens that contain willemite are more valuable, since they are harder to come by.  This specimen contains just calcite and dolomite.
