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: 4 x 2 x .25-inches
Notes:
Here is a nice multi-colored idrialite specimen from the Eureka Mine in California.  The specimen is a sawcut slab.  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.

Name: Calcite, Scheelite
Location: Bonito Mine, Near Oracle, Arizona.
Size: 4 x 4 x 2.5-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.

Size: 3 x 2.5 x 1.25-inches
Notes:
Here is a beautiful glassy green opal from a new find in Wyoming.  The mine owners have named it the King Green Opal Mine.  Much more glassy in appearance than the green opal from the Peacock Mine in Virgin Valley, Nevada.  The fluorescent response is an extremely bright green, under shortwave and longwave ultraviolet light.  So bright you can read by this material!  The specimens are difficult to obtain from the seam, especially larger specimens.  Power equipment must be used, and great care must be taken in order to keep the specimens from damage.  There is also a white opal that is mixed with the apple green.  It fluoresces very well, but not quite as nice as the apple green.

Name: Wollastonite, Aragonite?
Location: White Knob Quarry, Lucerne Valley, San Bernardino County, California.
Size: 3 x 2.5 x 1.5-inches
Notes:
Here is a nice two color specimen from the White Knob Quarry in California.  The specimen contains a yellow fluorescing wollastonite, with a beautiful violet/blue aragonite?  Several years back I had this fluorescing violet material analyzed twice, at two different places.  The analysis in both cases came back wollastonite.  However, this violet 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.

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: Sphalerite
Location:
Horn Silver Mine, San Francisco Mountains, Beaver County, Utah.
Size: 4.5 x 2.5 x 2.5-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: 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: Selenite
Location: Near Benson, Arizona.
Size: 3 x 1 x 1.25-inches
Notes:
Here is a specimen of fluorescing yellow selenite from the well known selenite locality near Benson, Arizona.  Many fine specimens have come from this locality.  The locality is bittersweet to me as a long time friend and geologist colleague was killed there a few years ago while collecting selenite.  The outcropping has apparently become very dangerous now so please do not try to collect there.

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.

Name: Powellite, Chalcedony, Aragonite
Location:
Near Picacho, Pinal County, Arizona.
Size: 5 x 4 x 3-inches
Notes:
Here is a very nice specimen from a new find in Arizona.  The specimen consists of a bright creamy yellow fluorescing powellite, green fluorescing chalcedony and some grayish fluorescing aragonite.  It is not often that you see material with the color combination of creamy yellow and green, so I am excited about this new find.
