      A 6 by 4 inch specimen of Calcite,Willemite, and Hardystonite from the     Sterling Hills Mine, Franklin, New Jersey.    






Fluorite Crystals from Weardale, England.







A beautiful thin crystal structure of deep red Calcite from Charcas, San Lois Postosi, Mexico.
 

                               

Wernerite from Ontario, Canada.


                 


                 

            Cupro - Scheelite (Green with yellowish tint) from Sharon-Marie Mines in Plumas County, California.  This specimen alone with other specimens of Scheelite, Powelite, and secondary Uranium ore came from my fathers Uranium mines in the 1940s.

Cupro - Scheelite usually fluoresces yellow with a faint tinge of green.  It is a Calcium Tungstate with Copper present and is usuallly quite hard.


                

      Scheelite from the Sharon-Marie Mines in Plumas County, California.        



                     
             

Coarse grained Willemite on Hardystonite from the Sterling Hills Mine, New Jersey.




     

A 1 inch in diameter gem quality Sodalite sphere from the Tunulliarfik area in Greenland.  The specimen was enlarged to show the detail of the Sodalite.  The black matrix is unknown.

    
 
 A 3" by 3" by 2" deep specimen of gem quality Tugtupite with Analcime from Kvanefjeld Mountain in the NW corner of the Llimasussaq Complex in Greenland.

                 
A very fine 6" by 4" specimen of gem quality Tugtupite and traces of Polylithionite from the Kangerlusrsuk Fjord near the Southeast boundary of the Limaussaq Complex in Greenland.
                      



A 4" by 3 1/2" by 1 1/2" clear Calcite Crystal of optical quality that fluoresces a deep blue color.  It will also phosphoresce a very brilliant vivid pale blue color that lasts for 40 seconds and fades when the shortwave ultraviolet light is turned off.  This piece of Calcite came from Terlingua, Mexico.




A 2" by 1 3/4" specimen of Scheelite (rich powder bluish-white fluorescents) on Muscovite from Pingu Sichuan Province, China.

 

         A  4" by 3" specimen of coarse-grained Sphalerite showing a fine pinkish- orange        fluorescense  with a trace of Wellimite and Hardystonite from the Sterling Hills Mine, Franklin, New Jersey.



 

 

 

This is a 6" by 3" specimen of Pectolite which fluoresces a pale blue-green-pinkish color from Lake County, California.  This specimen has a unique phosphorescent color when the shortwave ultraviolet light is turned off.  The Pectolite then phosphoresces a Brilliant splashy pastel blue-green-pinkish color that lasts for about 5 seconds.  This is an exceptional specimen of Pectolite.


        

A 7" by 3" rare specimen of Esperite, Willemite, and Hardystonite from the Sterling Hills Mine, Franklin, New Jersey.



A 5" by 4" specimen of thin Selenite Crystals from the Red River Floodway, Winnipeg, Manitoba, Canada.

A 3" by 1 1/2" specimen of a rich granular mass of Fluorescent Barite (white) on Calcite (red) from the Sterling Hills Mine, Franklin, New Jersey.

 

          

  A 3" by 3" specimen of clear rectangular optical Calcite fluorescing a deep red color from Claypool, Arizona.



Two specimens of Calcite, one fluorescing a Brilliant Blue White (2" by 1") and the other a pale pinkish blue from Arizona.  When the ultraviolet light is shut off the phosphorescence is a very vivid powder blue color and fade in about 40 seconds.
 

 

Hydrozincite fluorescing a brilliant blue-white from Nevada.



Calcite fluorescing  a yellow-green from the Manhatten Mines in Lake County, California.




A specimen of Aragonite Crystals (fluorescing bluish-white) on Sulfer (fluorescing a dull
                                               red) from Racuimuto, Sicily, Italy





A  3" by 1 1/2" specimen of Dakite (Uranium Oxide, a  secondary deposit fluorescing a bright green) on matrix.  This specimen
came from the Sharon Marie Mines in Plumas County, California.  At 1" with an open window Beta-Gamma radiation detector the specimen reads 0.15 mr/hr.


             A 6" by 4" specimen of Sodalite from the Ilimaussaq Complex in Greenland

 
                


"The Universe" displayed by a 4" by 3" specimen of Phlogopite (green fluorescense) and
Diopside (blue-white fluorescense) from Newcomb , New york.  The blue-white represents brilliant blue classification of very hot stars in the early formation of the Universe.  As these giant stars became super nova they ejected gases and mass (green) to form the asteroids, planets, comets, and dark mass left over during the formation of our Universe.
