Mineral Sets, Assortments, &

Reference Specimens

Mineral Sets - these more or less materialize from whatever loose specimens happen to be sitting around in boxes at the moment (if any). What appears on this page is what we have available at the moment. If there's something you're looking for, though, give us a call (# is at top of most pages on this site) or send an email.

Reference Specimens:  these are lower-priced individual specimens that are good for teaching and/or learning geology and mineralogy.  They are also good for collectors who are just starting out.

For an explanation of abbreviations used, please see our guide to mineral sizes.

10-piece Short-Wave Fluorescent Minerals,
Miniature or large-TN size, all from Franklin & Ogdensburg, NJ.
A quality mini-collection containing ten short-wave fluorescent  specimens.  This one has a couple of rarities.

1.)  Microcline (fl. pale blue-gray SW) w/ Calcite (fl red-ora. SW) - Franklin, NJ.   Also contains a couple of NF minerals including andradite (honey-brown in daylight).

2.) Hyalophane (fl. magenta SW) w/ Willemite (fl. green SW) with dark plates of Hendricksite (mica, NF) -  Franklin

3.) Sphalerite var "Cleiophane" (fl. orange, blue SW, MW, LW, PH) w/ Calcite (fl. red-ora. SW) - Franklin, NJ

4.) Cuspidine (tiny specks) (fl. yel-orange SW) with spots of Hardystonite (fl. blue-violet SW) in Calcite (fl red-orange SW) - Franklin, NJ.  Rare.

5.) Hydrozincite (fl. blue-white SW) with non-typical fl. Calcite (fl. yellowish SW) - Sterling Hill, Ogdensburg, NJ.  This is an unusual secondary calcite from the old Passaic Pit area.

6.) Calcite (fl. red SW) & Willemite (fl. green SW) in a Franklinite (non-fl) matrix.  - Franklin, NJ

7.)  Hardystonite (fl. blue-violet SW) w/ some Willemite (fl. green SW) - Franklin, NJ.

8.)  Calcite & Willemite var. "Polka Dot Ore" - fl. red-orange SW spots in a non-fl matrix of pyroxene - Franklin, NJ.  Technically this wasn't really an ore rock, because there's not much willemite, no zincite, and no franklinite. 

9.)  Hyalophane (fl dull magenta SW) with Willemite (fl green SW) - a more shiny, semi-translucent variety of hyalophane with andradite garnet (NF).  Franklin, NJ.

10.)  Xonotlite (fl indigo-violet SW) on Hyalophane or Celsian (very weakly fl or NF) - Parker Shaft, Franklin, NJ.  Rare.

This is a unique set;  no other set will contain exactly these pieces, and probably not even the same assortment of mineral types. 

You will receive the actual set pictured. 

Please note that this set requires a short-wave (SW) lamp (not included) to see the colors.  Only one or two of the specimens will fluoresce in long-wave (LW).

Specimen sizes range from about 1 3/4 to 2 1/4 inches across max. dimension.

Fossiliferous Sandstone - Brachiopods (mixed moulds and casts) stained with "Limonite" and Hematite - Pennsylvania. Matrix is a compact, gray, Ordovician or possibly Silurian sandstone. Fossils are not our specialty, so it's up to you to figure out what types of brachiopod are here (if we had to make a wild guess, Sowerbyella and/or Dalmanella). These are nice to look at with low magnification (no more than 5x).
