  • Floridas Geological Treasures

    Florida is a land of geological wonders, from its little-known earthquake history to the rich new fossil hunting grounds constantly being revealed by commercial development and quarrying activity. Much more than a fashionable resort or retirement destination. Florida ranks fifth in mineral production among all the United States. Florida's surprising mineral wealth ranges from commercial mines to coral islands; from valuable industrial metals like zirconium and titanium to such collectible treasures as chalcedony, ivory, petrified wood, and stunning crystals. You can gather Florida's mineral riches from the waters of the state's 34 major rivers, or find them waiting in the darkness of its 375 dry caves. Alongside a wondrous number of fossil remnants of such prehistoric creatures as jaguar, tapir, and mammoth, you will unearth arrowheads, stone knives, and other relics of the tools early man hunted them with. This book will tell you where to collect every type of mineral and fossil in Florida, and explain how they got there. Maps of the collecting areas, tips on carving, collecting, tools, and techniques for identifying and preserving your finds will help you prepare to uncover the remarkable variety, beauty, and wealth of Florida's geological treasures. Iris Tracy Comfort is the author of eight previous works of fiction and nonfiction, including two other books about rocks and minerals. She has worked as a reporter and scriptwriter, and has published numerous magazine articles and syndicated features. A frequent lecturer and seminar teacher on writing, she lives in Orlando, Florida.

  • Rockhounding Utah

    Author William A. Kappele shows you the grandeur of Utah's exposed formations, its canyon walls etched with fossils, and the spires and arches of the Needles District in Canyonlands National Park. Each description includes concise information on the material to be found there, the tools to bring, the best season to visit, the vehicle to drive, or when a remote find suggests it's time to lace up the hiking boots. Readers will glean new insights into the obsidian of the Black Rock sites, jasper at Hell's Backbone, petrified wood at Bullfrog Turnoff, and fossils of sea lillies along the Wasatch Range. May your journeys be fruitful and your bag be heavy on the way home. Somewhere in that bag among your rocks, we hope you haven't forgotten your copy of Rockhounding Utah.

  • Mineral Hardness Scale Ruler

    The Mineral Hardness Ruler is a stimulating visual aid, educates in one phase of mineralogy, and provides the standard ruler measurement scales needed in classes.


    Rockhounds, mineral enthusiasts, students, teachers, geologists, and any one interested in rocks and minerals will find the Mineral Hardness Ruler a handy visual aid for quick information on mineral hardness.



    The two-sided, flexible, glossy, vinyl ruler consists of five scales: three measurement scales and two mineral hardness scales. The measurement scales are in standard ruler measurements of tenths of inches, sixteenths of inches, and millimeters. Mohs' relative hardness numbers are integrated into the inch scales, while a separate scale exists for an absolute mineral hardness scale by Rosiwal.


    On one side of the ruler are pictures of the ten common minerals, in full color, selected by Mohs for his relative hardness scale. On the reverse side of the ruler are six common items with their relative hardnesses. These items, along with known minerals, can be used as a handy field kit to test the relative hardness of an unknown mineral.


    Hardness is one property of a mineral that can be used to distinguish among similar minerals. A given mineral can scratch any other mineral of the same or softer hardness. Over a hundred years ago, the German mineralogist Frederick Mohs devised the relative hardness scale that has found favor with mineralogists for over a century. Others, such as Rosiwal, formed absolute hardness scales using the same minerals as Mohs. For example, diamond, the hardest substance in Nature is not twice as hard as apatite, 10 versus 5, but over twenty thousand times as hard, 140,000 versus 6.5.

  • Deluxe Moh's Mineral Hardness Pick Set

    The Deluxe Moh's Hardness Pick Set now comes in two case types. The wooden case is small enough to carry and the top screws into the base to make a perfect desk stand. The plastic case is longer but the thinner size makes it easier to carry in your field tool set.

    Hardness is an important and quantifiable physical characteristic of a mineral and in your effort to identify an unknown mineral, the hardness, if known, combined with other properties, can narrow your search to just a handful of possibilities. Simply scratch a smooth surface of your unknown mineral with the picks of various indicated hardness. As an example, if a No. 5 pick scratches the mineral, but a No. 4 pick does not, then your mineral hardness is 4.5. Then compare this against a table of minerals listing hardness values to aid in identifying the unknown mineral.
    The Deluxe Mohs' Hardness Pick Set from Mineralab is unique in that, unlike other mineral hardness test tool that use minerals or crystal points, Mineralab picks are made of metals and alloys of hardness values equal to 2 through 9 on Mohs hardness scale. Because the picks are made of metal, they are easily ground to sharp points which will not break off and which can be easily sharpened.

    What is included in the Mineralab's Deluxe Mohs' Hardness Pick Set?

    • Four double-ended picks with eight points comprising 2 and 3, 4 and 5,
      6 and 7, 8 and 9 on Mohs’ hardness scale.

    • High quality brass pinch vises.

    • A glass plate (hardness of about 5.5) which, when scratched,
      quickly distinguishes hard from soft minerals.

    • A second hardness plate with a hardness value of 3.5.

    • A streak plate for testing a mineral’s streak color.

    • A magnet to test magnetic rocks such as magnetite and pyrrhotite.

    • A 100 grit polishing stone to keep the points sharp.

    • An attractive, mahogany-finished and compact wooden case.

    • Complete usage instructions.


    Other Features:

    • All points are stamped with the indicated hardness value, and each double-ended
      pick body is color coded for quickly finding the desired pick.

    • Hardness points can be easily and inexpensively replaced without having to
      replace the pick bodies.

    • Compact. The wooden storage case is only 7" tall by 2.5" wide.

    • Also use to test hardness of various materials encountered in the industrial,
      excavation, and archeological fields.

    • 1 Year Warranty
    If you are ordering only a Deluxe Moh's Hardness Pick Set you can save money on shipping by choosing USPS Priority Mail. We will use a USPS Priority Mail Small Flat Rate Box and I'll adjust your total to pass the savings back to you.

  • Prospectors Rock Hammer

    Prospector's Rock Hammer

    The Prospector's Rock Hammer is a very light duty rock hammer with a 22 oz. drop forged head and a tubular handle with rubber grip. The hammer head is larger than the Estwing Rock Hammers. The pointed end is not tapered to the extent of nor is it as long as the Estwing Rock Hammers. This is not a tip for digging fossils as it is not tapered enough to really penetrate into sandstone. The larger hammer face, the thin grip, and the duller pointed end make it a great starter rock hammer for children when you're not sure the young geologist is going to stay interested.

    Cheap enough that you can throw one in each of your vehicles just in case you come across an interesting roadcu.., er..., outcrop.

    The Prospector's Rock Hammer is for light duty or use with soft rock. The hammer head is pressed onto a tubular steel handle. Since it isn't one solid piece of drop forged steel like the Valley Rock Hammer or Estwing Rock Hammers it can't be used for prying out specimens. As with any two piece hammer, after a little use the head will become detached from the handle. Best used as a hammer for young children without the upper body strength to really swing a hammer with any force. Consider this a toy or a one time use hammer.
