Bob Jones Tribute

It is with great sadness that I must report the passing of a mineral legend. Mr. Robert W. Jones Jr. (Bob Jones) passed away on May 31, 2024, at 97 years young. Not only was Bob a great friend of mine, he was also a great friend to the fluorescent mineral community. As many of you may know, Bob was a mineral legend to the white light and crystal collectors. However, his love and interest in fluorescent minerals helped to give the fluorescent mineral hobby some respect (something that was severely lacking in the white light mineral collecting circles).

Like many of us, Bob’s first encounter with minerals was when he first saw a fluorescent mineral display at the Yale Peabody Museum in 1935. That encounter propelled his interest in the mineral world. Bob went on to teach for over 30 years. He first began his writing career with a column “Collecting Fluorescent Minerals” in Rocks and Minerals magazine in 1960 and by this time had built a significant fluorescent mineral collection. His first two mineral publications were about fluorescents – “Luminescent Minerals of Connecticut” (1960), which was also his master’s thesis, and “Nature’s Hidden Rainbows” (1964). Bob went on to share his knowledge and passion for the mineral collecting hobby through the many books he authored, hundreds of mineral articles and columns (primarily in Rock and Gem magazine from 1971-2024), numerous mineral videos, countless live presentations, and as host of BlueCap Productions “What’s Hot in Tucson”. His articles appeared in many magazines including Rocks and Minerals, Rock and Gem, The Mineralogical Record, Lapidary Journal, Arizona Highways and Le Monde et Minereaux. Bob was on the Tucson Gem and Mineral Show Committee for over 40 years, making him an expert on the history of the largest mineral show in the world. He shared that knowledge in a book entitled “50-Year History of the Tucson Show”, published by the Mineralogical Record in 2004.

In 2022 Bob was inducted into the Fluorescent Mineral Society Hall of Fame for his work that inspired a generation of new fluorescent mineral collectors, at a time when the hobby was in its infancy. Prior to his passing he was Editor Emeritus at Rock and Gem magazine. Among his many honors and awards, the most prestigious is the Carnegie Mineralogical Award, presented in 1998 to honor his work. At the time, the Carnegie Museum’s mineral section curator Marc Wilson was quoted as saying “Bob Jones’ selfless dedication to the hobby and science of mineralogy is exemplary. His grassroots efforts as a lecturer, author and editor have inspired generations of budding mineralogists”. The mineral bobjonesite was named in his honor in 2003. He was an honorary or life member in numerous mineral clubs and societies. With over 80 years of mineral collecting all over the world behind him, Bob certainly has earned the title of a Mineral Legend!

Two Favorite Personal Stories

In the late 1990s I was working on putting together a fluorescent mineral education kit for kids. I wanted the kit to be the best one available on the market. I knew it had to have a longwave ultraviolet lamp with it, but at the time, it was difficult to find a good quality but inexpensive longwave (BLB) lamp. When I finally was able to complete the kit at the quality I required, I showed it to Bob. I told him this was my way of getting young kids into the fluorescent mineral hobby. Bob’s eyes lit up when he saw it and was very impressed with the kit. He really enjoyed the fact that the kit came with an educational pamphlet that I wrote inside. I certainly didn’t expect anything from Bob except maybe some kind words of encouragement. To my surprise, Bob wrote an article about the kit in the December 2001 issue of Rock and Gem Magazine! That’s the type of guy Bob was. Thank you again Bob!

In March 2007 I received a call from Bob. He said, “hi George, this is Bob Jones and I think I have some nice rocks you may want”. Apparently, an old friend of Bob’s passed away back in Connecticut. The mans widow contacted Bob to see if he could help disperse the mineral collection. I told Bob he was welcome anytime to stop by and show me what he had. I think he came by the next day! Bob brought with him several fantastic willemite/calcite vein pieces from the Buckwheat Dump in Franklin, New Jersey. Bob told me they were collected around the time of World War II (WOW). He also brought over several nice esperite specimens that he knew I would want. After some negotiations, we reached a deal and the specimens became mine. I was honored that Bob thought highly enough of me to offer these specimens for my collection. After the deal was made, we sat in my living room and talked rocks for another hour or so.

For those of you who have seen my museum room at the house, the large willemite/calcite vein piece at the top center of my Franklin, New Jersey display is one of the specimens I purchased from Bob that night. To this day it is one of my favorite specimens.

I, along with everyone who knew him, will miss him dearly. He was one of a kind and a true mineral legend. Rest in peace Bob and may God bless.

34 new fluorescent minerals to the Green Envy Mine Showcase

Today I am excited to offer for sale 34 specimens from a new mine in Arizona.  The mine is called the Green Envy (the Mine) and is a newly discovered locality for the rare lead silicate wickenburgite.  As you may recall, the Potter-Cramer mine is the Type Locality for wickenburgite, having been identified in 1968.  



So far, the fluorescent minerals that have been identified at the Mine are wickenburgite, willemite, calcite and caliche.   Like the Potter-Cramer mine, the wickenburgite can fluoresce anywhere from a Bazooka bubble gum pink to a crimson red.  Unlike the Potter-Cramer mine, the willemite fluoresces more of a creamy yellow green to a bright vivid green (hence the name Green Envy).  Under midrange and longwave ultraviolet light, the willemite can fluoresce yellow.  After exposure to shortwave ultraviolet light, the willemite exhibits a long duration sustained luminescence (aka phosphorescence).



Another difference between the Mine and the Potter-Cramer mine is that fluorescent orange-red calcite can be found with the fluorescent wickenburgite and willemite.  The Potter-Cramer mine did not have calcite but had significant amounts of fluorescent fluorite, which has yet to be found at the Mine.



So far, the Mine has been hand mined starting at the ground level.  The owners hope that if sales of these specimens go well, they can conduct further mining efforts.  We do not know how many more quality specimens the Mine will produce.   Polman Minerals will continue to hand pick each specimen for sale based on quality, richness and aesthetics.



A history of the Mine, as well as other information, can be found at the beginning of the Showcase page which has been dedicated to specimens from the Mine.  If you have any questions about this new locality in Arizona, please let me know.


I am currently photographing specimens for a new US Showcase.  As always, those on my email list will be notified the moment these new specimens are uploaded to my site.  

43 new fluorescent minerals to the Franklin/Sterling Hill Showcase

1) Today I have added 43 new specimens to the Franklin/Sterling Hill Showcase page of my website.  Some sample photographs are included above.  I recently acquired a very nice collection of Franklin/Sterling Hill specimens.  This collection included such Franklin mine classics as margarosanite, “third find” as well as fibrous wollastonite, esperite, barite, xonotlite, prehnite, roeblingite, manganaxinite, 3 and 4-color specimens, hardystonite crystals etc.   This collection also included the well-known “Snoopy” piece of calcite, hardystonite and esperite featured in Manny Robbins’s first book (#61, plate 16).  Specimens from the Sterling Hill mine included such classics as “beta” willemite, exsolution willemite, calcite/barite, mylonitic ore etc.

2) It’s not often quality specimens like these from the Franklin mine become available for purchase.  My advice would be to purchase them while you can!   

3) I am currently photographing specimens from a new mine in Arizona that I am very excited about.  Information about this new mine will be included on my website when the time comes to release specimens for sale.  As always, those on my email list will be notified the moment these new specimens are uploaded to my site.  

New Blog on website

Instead of the What’s New page on my website, I have decided to turn that into a blog page.  All the information about new minerals posted that I put in my customer emails, I will now make part of the blog page as well.  This way people who view my website, that are not on my email list, will get the opportunity to read the information I provide in my customer emails.  Also, people can always go back to read an earlier post if there is some information that they forgot.

36 new fluorescent minerals to Worldwide showcase

Today I have added 36 new specimens to the Worldwide Showcase Page of my website.  There are four main batches to this update, as well as many single specimens.  A description of some of the larger batches is provided below.


A) Aragonite from Sicily – Just got in a new batch of Sicilian aragonite specimens directly from Italy.  These specimens are mostly display and large display size specimens.  They range in fluorescent longwave response from pale pink to dark pink and even red/pink.  They all exhibit a nice color change to pale greenish/white when under shortwave ultraviolet light.  After exposure to shortwave ultraviolet light, the specimens exhibit a sustained luminescence.

B) Amber from Indonesia – Deep brown amber from the Oligocene Epoch (30 mya).  Under longwave ultraviolet light this amber fluoresces a beautiful cornflower blue.  Although not a mineral, fluorescent amber sometimes makes a nice addition to a fluorescent mineral collection.

C) Tugtupite from Greenland – A couple of nice tugtupite specimens from Greenland, including a real aesthetic specimen with a uranyl activated green mineral from Kvanefjeld.  Tugtupite fluoresces a beautiful pinkish red color under shortwave ultraviolet light with a nice color change to orange under longwave ultraviolet light.D) Calcite and willemite from Australia – A couple of nice multi-colored specimens from the Puttapa Mine in Australia.   The willemite in these specimens fluoresces in a range of colors.  Some of the willemite  also has a nice color change to yellow under longwave ultraviolet light.  The willemite also exhibits a long duration sustained luminescence.

43 new fluorescent minerals to United States Showcase

Today I have added 43 new specimens to the United States Showcase Page of my website.  A description of some of the larger batches is provided below.

A) Sphalerite from Pennsylvania – I was recently able to obtain a nice batch of multi-colored sphalerite specimens from a new find in Pennsylvania.  As with the sphalerite I sold awhile back from the new find in Montana, these sphalerite specimens require a longwave LED flashlight to really enjoy the fluorescent colors.  As noted in the notes section below each photograph, these sphalerite specimens were photograph using a C8+ longwave LED flashlight.  I do have these flashlights for sale if you would like to purchase one along with a specimen.

According to the field collector of these specimens there are two veins.  In one vein the sphalerite can fluoresce red, orange and pink (and rarely blue).  In the other vein the sphalerite fluoresces orange and pink.  In both veins you can also get a cherry red fluorescing dolomite.  Some specimens contain secondary hydrozincite, smithsonite and in some cases cerussite.  The sphalerite is triboluminescent as well.  The collector of these specimens has told me that if there appears to be a good demand for these, he can provide me with more specimens.

B) Sphalerite from the Sweet Home mine in Colorado – Over the past few years my good friends at Collector’s Edge minerals have been putting aside for me the best specimens of fluorescent sphalerite from the Sweet Home mine.  These specimens are the result of the trimming process as they work to expose the rhodochrosite.  As a result, some specimens have sawcut faces.  Although these sphalerite specimens fluoresce under longwave tube lighting, they really are bright and beautiful under longwave LED lighting.   These specimens were photographed using a C8+ longwave LED flashlight.  Specimens may also contain fluorescent violet fluorite (in some cases chlorophane).

C) Willemite, Calcite, Fluorite from the Purple Passion Mine in Arizona –  For this batch I put together a few nice “A” grade pieces from the Purple Passion Mine in Arizona.  I also included a nice large display piece that would be perfect for a center piece of a display.  Some of the calcite from the Purple Passion Mine fluoresces more brightly under midrange ultraviolet, although shortwave ultraviolet alone is still alright for this material.

D) Eucryptite from the Midnight Owl mine in Arizona –  I grabbed a few nice specimens of crimson red fluorescing eucryptite from my stock.  These pieces come from the famous Midnight Owl pegmatite mine in Arizona.  Some of these specimens also contain a fluorescing spodumene (spodumene can typically alter to eucryptite).   Capturing the brilliant crimson fluorescent color of eucryptite with digital cameras is tricky.  As a result, I put a note saying that the specimens did not photograph well.

My tribute to Claude Poli

It is with great sadness that I must pass on the news that my dear friend Claude Poli passed away on February 15, 2024.  Claude lived in New Jersey and was a long-time collector of Franklin/Sterling Hill minerals.  I think the first time I met Claude was at the Franklin Mill Site in the early 1980s.  We became very good friends shortly thereafter.  Not only did we share our love for fluorescent minerals, but we shared our love for classic rock and roll and our favorite band, The Who.  We would spend hours on the telephone, first talking about any new fluorescent minerals I had for sale, and then always finishing up the conversation about The Who and rock and roll in general.  Whenever I found a new book or video on The Who I would always send him a copy, which he greatly appreciated.  The last time I saw Claude was in 2019.  I had traveled east with three of my dear friends from Arizona.  We were attending the September Franklin mineral show.  When we arrived in New Jersey our first stop was to visit Claude.  My friends enjoyed meeting Claude and had a wonderful visit.  Claude not only had many stories to tell but had great minerals to see and to purchase.  We all appreciated his hospitality and kindness.  It was a visit I don’t think my friends will forget and I am glad they all got to meet him.
 
I greatly admired Claude’s ability to field collect.  He was incredibly aggressive with both his field collecting and his purchasing of fluorescent mineral specimens.  His love for the hobby was unmatched as he put together amazing collections.  Over the years he would provide me with large quantities of self-collected specimens for my business.  I still have lots of these specimens in my inventory today.  My personal collection is also filled with specimens I have purchased from Claude over the many years I have known him.   I’m sure there are many people in the hobby that can say the same thing.  To me he was an icon in the Franklin community and will be missed by many.  I know I will miss him and his bandana and suspenders!  I will also miss the hour-long telephone conversations I have had with him.
 
Rest in peace my good friend, may God bless.  Till we meet again.

 37 new fluorescent minerals added to the Worldwide Showcase

Today I have added 37 new specimens to the Worldwide Showcase Page of my website.  A description of some of the larger batches is provided below.

A) Marialite from Afghanistan – I was recently able to obtain a nice batch of yellow fluorescing marialite crystal specimens from Afghanistan.  Along with the yellow fluorescing marialite can be found sky blue fluorescing diopside and in some specimens a red fluorescing calcite.

B) Multi-colored specimens from Greenland – This batch contains some specimens rich in ussingite with associated minerals tugtupite, sodalite, analcime, polylithionite as well as chkalovite. 

C) Cerussite from Morocco – This batch contains the typical tan colored cerussite crystals with associated barite and galena on matrix.  Some cerussite specimens from Morocco fluoresce best under longwave ultraviolet light while others fluoresce best under midrange ultraviolet light.

D) Calcite and Dolomite from Austria – This batch contains interesting patterns of secondary calcite within a dolomite matrix.  The collector of these specimens calls them “Network Calcites”.  The material was found at an outcropping in Salzburg, Austria.  The calcite fluoresces a bright white in both shortwave and longwave ultraviolet light, with some of the calcite fluorescing red under shortwave ultraviolet light.  The white fluorescing calcite exhibits sustained luminescence.
