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: Sphalerite
Location:
Horn Silver Mine, San Francisco Mountains, Beaver County, Utah.
Size: 2.5 x 2.5 x 1.5-inches
Notes:
Here is a multi-colored brecciated specimen of fluorescing sphalerite from the famous Horn Silver Mine in Utah.  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!  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: 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: Calcite, Scheelite
Location: Bonito Mine, Near Oracle, Arizona.
Size: 4 x 3 x 2-inches
Notes:
This is a nice two color specimen containing scheelite and calcite from the Bonito Mine in Arizona.   I originally staked a claim on this mine some 20 years ago.  However, the BLM got back to me and told me the land was not available for claim due to some land trade with the previous owners and the Forest Service.  The scheelite fluoresces a bright sky blue under shortwave ultraviolet, and the calcite fluoresces a bright red.   For anyone putting together an Arizona collection, a specimen from this mine is a must.

Name: Caliche
Location: Daisy Fluorspar Mine, Nye County, Nevada.
Size: 5 x 2.5 x 1.5-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.

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.

Size: 3 x 2.5 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.

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: Wollastonite, Aragonite?
Location: White Knob Quarry, Lucerne Valley, San Bernardino County, California.
Size: 2.5 x 2.5 x 1-inches
Notes:
Here is a nice small two color specimen from the White Knob Quarry in California.  The specimen contains a medium yellow fluorescing wollastonite, with a patch of a beautiful purple/blue aragonite? (appears blue in the photograph but the true color is an intense purple/blue).  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: Calcite, Willemite
Location: Puttapa Mine, Puttapa, North Flinders Ranges, Flinders Ranges, South Australia, Australia.
Size: 2 x 2 x 1-inches
Notes: 
Here is a nice little specimen of willemite and calcite from a relatively new find in Australia.  The material comes from the Puttapa Mine, a large open pit zinc mine.  Material that has recently come from this mine has been very aesthetic, with different patterns and colors.  Though not much technical work has been done on this material, it appears that the willemite can fluoresce green to bluish white under shortwave, yellow under midrange and has a bright green phosphorescence.  The calcite fluoresces red under shortwave.  This specimen exhibits a very good color change.

Size: 2 x 1 x 1-inches
Notes:
This is a nice little specimen of aragonite from the sulfur mines in Sicily.  The mines have been closed since at least the 1980s.  This specimen has a nice crystal cluster.  The specimen has been saw cut on the back and one side.  This aragonite exhibits a color change from a bright creamy greenish white under shortwave ultraviolet light, to a light pinkish color under longwave ultraviolet light.  This material will also exhibit a light green phosphorescence as well, with a fairly long duration.

Notes:
Here is a nice specimen of fluorescing creamy white/yellow calcite from Bermuda!!   It’s not very often that you see fluorescent specimens from Bermuda, but I obtained this material about 25 years ago from a vacationing collector.  The calcite will fluoresce under all three wavelengths, with longwave providing the best results.  There is some minor phosphorescence to the calcite as well, after exposure to shortwave ultraviolet light.

Name: Calcite
Location: Chihuahua, Mexico.
Size: 3.5 x 2 x 2-inches
Notes:
This is a nice specimen of calcite showing both zoning and two color fluorescence.    Some of the specimen fluoresces bright creamy yellow, while other portions fluoresce a pinkish orange color.  The pinkish color is better seen in person.  Specimens collected from this locality are usually etched with acid to remove lime scale.  This specimen was broken from a larger specimen, so portions are not acid etched.  The main face photographed above is a natural face.  This material exhibits a very unusual combination of color.

Name: Calcite, Fluorite
Location:
Pure Potential Mine, La Paz County, Arizona.
Size: 4 x 5 x 3-inches
Notes:
Here is a beautiful display size specimen of calcite and fluorite that was collected down in the Pure Potential Mine when it was in operation, and has not been weathered as those collected on a surface dump.  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 violet and the calcite red, this color combination puts the colors on each end of the visible 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.

Location: Manhattan Mine, Knoxville, Napa County, Californa.
Size: 1.5 x 1 x 1-inches
Notes:
Here is a small but brilliantly fluorescing yellow specimen of opal that was collected decades ago from a mine now closed.  The opal will fluoresce under shortwave and midrange ultraviolet light, but longwave provides the best response.  This unusual yellow opal was collected by Mr. Jerry Whitaker, who passed away a few years ago.  Although I never met Jerry, he was extremely generous to deal with.  From what I understand, he had a wealth of knowledge about the geology and mineralogy of the north Bay Area.  He will be missed by all who knew him.

Size: 4 x 2.5 x 1.5-inches
Notes:
Here is a nice three color specimen from Afghanistan.  I have heard from multiple sources that specimen mining from this area has been significantly reduced lately.  As a result I have been buying specimens from my local contacts that have been in storage for quite some time.  This specimen contains highly phosphorescent hackmanite, which fluoresces orange, red fluorescing calcite and an unknown fluorescing light blue mineral.  The light blue mineral may be albite.   If anyone knows for sure what the blue fluorescing mineral is, please let me know.

Name: Calcite, Aragonite (Septarian Nodule)
Location: Near Orderville, Kane County, Utah.
Size: 5 x 4 x 3-inches
Notes:
Here is a nice sample of a septarian nodule from Utah.  This classic material is usually sold as cut slabs or in some shape that has been carved and polished.  I believe there is still several theories on the origin of these really pretty nodules.  When you have a full nodule that is cut in half (like a geode), they can be really pretty inside, with various patterns and colors.  This specimen has been broken and not cut, making it the perfect specimen for the purest out there who prefers not to have cut specimens.  The specimen above contains orangey yellow fluorescing calcite crystals in tiny vugs, and creamy white aragonite that is surrounding some of the non-fluorescent rock within the nodule.  The yellow fluorescing calcite is best under longwave ultraviolet, and the aragonite is best under shortwave ultraviolet, but fluoresces very well under longwave as well.

Name: Sphalerite
Location:
Horn Silver Mine, San Francisco Mountains, Beaver County, Utah.
Size: 2.5 x 2 x 2-inches
Notes:
Here is a multi-colored specimen of fluorescing sphalerite from the famous Horn Silver Mine in Utah.  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!  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.
