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: Idrialite
Location: Eureka Mine, Sonoma County, California.
Size: 3 x 2.5 x 1-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.

Size: 2.5 x 1.75 x 1.5-inches
Notes:
Here is a small specimen of wollastonite from a find at the Noble Pit in the 1990s.  At the time I called this material “new find” wollastonite, for lack of any better name.  The wollastonite in this find is a darker yellow than you find in other localities in the mine.  The specimen is rich and also contains some fluorescent white aragonite on the top of the specimen.

Location: Midnight Owl Mine, Yavapai County, Arizona.
Size: 1.5 x 1.5 x .5-inches
Notes:
Here is a rich and bright eucryptite from the famous Midnight Owl mine in Arizona.   There are some pictures of me collecting at this site on my photograph page.  This specimen is a cut slab, which shows a fresh face of eucryptite on each side of the slab.  The eucryptite fluoresces a bright crimson red color under shortwave ultraviolet light.  The photograph looks more red than crimson, but the specimen does exhibit the typical crimson red response of eucryptite.  This piece would be excellant for cutting, polishing and mounting.

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: 1.75 x 1.5 x 1.5-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: 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: Hackmanite, Calcite, Dolomite?
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.  I have had some of this light blue material analyzed and it came back as dolomite.

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: Opal
Location:
Manhattan Mine, Napa County, California.
Size: 2 x 1.25 x 1.25-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 some 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

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.

Notes:
Here is a specimen of fluorescing green chalcedony from Arizona.  With a trace of uranium as an activator, this chalcedony fluoresces a bright green under shortwave ultraviolet light.  The area in the shortwave photograph that is white, is a small area where the chalcedony is even more bright than the surrounding chalcedony.  As a result, it was overexposed in the photograph.  In white light, the chalcedony is almost drusy in its appearance.

Name: Wollastonite
Location: Fengjiashan Mine, Hubei Province, China.
Size: 4 x 2 x 1.5-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 or violet.  It is most likely a rare earth activator that causes this midrange color response.
