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: Smithsonite, Willemite, Hydrozincite, Sphalerite
Location: Nellie James Mine, Miller Canyon, Huachuca Mountains, Cochise County, Arizona.
Size: 5.5 x 3.5 x 2-inches
Notes:
Here is a nice specimen from the Nellie James Mine in Arizona.  The main face of the specimen contains crimson red fluorescing smithsonite as well as green fluorescing willemite.  There is some longwave fluorescing orange sphalerite as well, but I did not photograph it.  On the back side of the specimen there is some sky blue fluorescing hydrozincite.  The specimens true value however, comes from the crimson red smithsonite located on the main face.  A nice rich specimen if your Arizona collection needs a smithsonite from the Nellie James Mine.

Name: Sphalerite
Location: Horn Silver Mine, San Francisco Mountains, Beaver County, Utah.
Size: 3 x 3 x 1.5-inches
Notes:
Here is a fine grained 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.  With this fine grained specimen, you can even spell your initials, using the phosphorescence and the 405nm laser!

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: Challenger Cave, Nuevo Leon State, Mexico.
Size: 2.5 x 2 x 1.5-inches
Notes:
Here is a small cleaved rhomb of calcite from the Challenger Cave locality in Nuevo Leon, Mexico.  This calcite is a “Terlingua Type” calcite, named for the famous calcite found from Terlingua, Texas.  This type of calcite exhibits a pinkish blue or blue response under shortwave ultraviolet light, and a more pinkish response under longwave ultraviolet light.  Some Challenger Cave calcite exhibits yet a third color under midrange ultraviolet (330nm best).  This specimen fluoresces a pinkish blue under shortwave (not quite as blue as in the photograph), and a very pale pink under longwave.  The specimen will also show phosphorescence after exposure to shortwave ultraviolet light.

Notes:
Here is a very nice small specimen of calcite from the Boccheggiano Pyrite Mine in Italy.  Many years back Tom Warren sold this material as strontian-aragonite.  The material has since been identified as calcite.  The Boccheggiano Mine is closed now, and good specimens from there rarely hit the market.  I had some very good ones for sale awhile back, and this was one from that batch that was a bit too small for a Showcase.

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
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: Wickenburgite, Willemite, Fluorite
Location: Potter-Cramer Mine, Maricopa County, Arizona.
Size: 3.5 x 3 x 1.5-inches
Notes:
Here is a specimen from the Potter-Cramer mine, a mine that I have owned since 2002.  This mine is the Type Locality for the mineral wickenburgite.  Wickenburgite is a rare silicate found in oxidized hydrothermal veins where galena was present.  Wickenburgite fluoresces under shortwave ultraviolet light.  The fluorescent response ranges from Bazooka bubble gum pink to crimson red.  At the Potter-Cramer mine the wickenburgite is commonly found with several other fluorescent minerals, including fluorite, willemite and chalcedony.  The willemite from this locality can range in fluorescent response from almost white, to green, with creamy yellow/green being most common (probably a combination of white and green fluorescing willemite). This specimen contains a nice balance of wickenburgite, willemite and fluorite.  The willemite is also phosphorescent in this specimen.  No Arizona collection is complete without a representative specimen of wickenburgite from this mine.

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.

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: 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.

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.

Size: 2.5 x 2 x 1-inches
Notes:
Here is an unusual specimen I picked up as part of a large collection.  It is from the famous Castle Dome Mining District, where the Hull Mine is located.  At first I thought the specimen contained fluorite, quartz and caliche.  However, when I checked the specimen with longwave, there was no fluorescent purple.  Not sure what is fluorescing purple in this specimen under shortwave.  The quartz (or agate) fluorescing green and the caliche fluoresces orange.

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.

Size: 3 x 2.5 x 1.5-inches
Notes:
Here is a nice 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.  There may also be some currently unknown minerals mixed in with the willemite and calcite.
