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: Opal
Location:
East of Manzano Mountains, Torrance County, New Mexico.
Size: 3.5 x 3 x 1.5-inches
Notes:
Here is a real nice milky white opal from a new find in New Mexico.  The opal was found at a road construction site before the entire outcropping was covered over.  The milky white opal has almost a pearly luster to it.  The fluorescent response is very bright green under shortwave ultraviolet light.  It will also fluoresce a bit under longwave as well.  The activator in this material is most likely a trace of uranium.  This is a nice specimen that is almost 100 percent opal.

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.

Size: 3.5 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 25 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: Wollastonite
Location: Fengjiashan Mine, Hubei Province, China.
Size: 4 x 3.5 x 3-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 or violet.  It is most likely a rare earth activator that causes this midrange color response.

Here is a two color specimen consisting of fluorescent sky blue diopside, with the rarer mineral fluoro-edenite, which fluoresces a creamy yellow.  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. Fluoro-edenite is in the amphibole group of minerals.  The chemical formula for fluoro-edenite is NaCa2Mg5(AlSi7O22)(F,OH)2.

Name: Calcite, Hydrozincite
Location:
Beaver, Utah.
Size: 3.5 x 2 x 1.5-inches
Notes:
Here is an interesting specimen from Utah.  The specimen contains fluorescent sky blue hydrozincte, along with fluorescent orange/red calcite (both shortwave). Under longwave ultraviolet light, the calcite does a nice color change, and fluoresces creamy yellow.  This specimen was part of several flats from this locality that I purchased from Tom Warren about 30 years ago.  At this time, Tom Warren was selling his inventory.  Tom Warren was the founder of UVP, Inc, and is considered the Godfather of the fluorescent mineral hobby.

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: 3 x 2 x 1.5-inches
Notes:
Here is a nice banded specimen of calcite and fluorite that was collected down in the Pure Potential Mine when it was in operation.  This specimen 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.

Name: Selenite
Location:
Red River Floodway, Winnipeg, Manitoba, Canada..
Size: 3.5 x 3 x 3-inches
Notes:
Here is a beautiful specimen of selenite from the world famous Manitoba, Canada locality.  This specimen is very clean, with very little crystal damage.  In white light it has a very nice luster to it.  The specimen will fluoresce under all three wavelengths, with longwave providing the best response.  The selenite is also highly phosphorescent as well.  If you are looking for a choice specimen from this locality, this may be the one for you.

Name: Hackmanite, Calcite, Albite?
Location:
Sar-e Sang, Koksha Valley, Badakhshan Province, Afghanistan.
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: Powellite
Location: Taylor Mine Complex, Crater Island District, Box Elder County, Utah.
Size: 3.5 x 3 x 1.5-inches
Notes:
Here is a nice specimen of powellite from a new fluorescent mineral find in Utah.  The specimen has a bit of a “starry night” look to it.  The powellite is very bright under shortwave ultraviolet light.  It fluoresces a deep creamy yellow.   From work that has been done on this material, it appears that this is true powellite and not scheelite with high molybdenum content.  I have a couple of nice display size specimens that will be placed on the website for sale in the near future.

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.

Name: Hyalite Opal
Location: Zacatecas, Mexico.
Size: 5 x 6 x 3-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 (this specimen was not photographed in daylight, so the daylight fluorescence is not seen).  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.  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.
