Bausch & Lomb 10x Illuminated Coddington Pocket Magnifier

Correction in the Coddington magnifier is achieved through the use of a single thick lens with a central groove diaphragm. This provides for sharp, crisp images.

A problem sometimes encountered in using a high power magnifier is the lack of sufficient light on the object. A bulb inserted in the groove of the Coddington lens illuminates the object being examined eliminating this problem. Requires two AA batteries (not included).

  • 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.
