Heavy duty 3/4'' plain black nylon loupe lanyard with a quick release buckle and a split ring. This lanyard may be used for any purpose but we've had it custom manufactured specifically for use with the BelOMO loupe.
Important: We offer this lanyard for no additional charge when you buy the combo package of the BelOMO loupe with attached lanyard. Attaching the lanyard requires a screw to be removed so let us do it. We've been doing it for years and you save money!
Use the split ring on loupes with a mounting hook. To use the lanyard with a BelOMO loupe remove one screw on the support shaft of your BelOMO loupe, swivel the frame out of the way and slide the end over the support shaft then install the screw again. Don't use the split ring to attach the lanyard to the loupe. (We suggest that you purchase the loupe with the lanyard already installed.)

This informatice guide covers the five billiion years of history that have given the earth its present form, including:
Illustrated in full color, this guide is valuable for everyone interested in our planet, the ultimate basis of our present society.
A Classic Guide .... for All Ages.
Our review:''We highly recommends this little guide. It provides a consice overview of geology, rocks and minerals. Great illustrations to help you understand the concepts. This is great reference, carry it in the field.''
This is a great little pocket guide to rocks and minerals. It uses color drawings to illustrate the rocks and minerals which I find is far more handy that pictures of museum quality specimens. Rocks and minerals in the field often don't know what they're supposed to look like so they are more average than those museum exhibits!
In this book two renowned experts share their lifelong passion for geodes and their extensive knowledge of world-class geode deposits as they present the latest theories on the formation and occurrence of these amazing mineral gifts of nature.
The most comprehensive book ever written on geodes of the Americas - a definitive reference for serious collectors and a delightful mineral exploration for both experts and novices.
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.
California Gold & Gems Maps, Northern Edition is a comprehensive collection to assist the rockhound in locating 40 gem sites. The source of information has been taken from numerous publications. All known types of rock and gem deposits could not be included because of the numerous types and locations would be overwhelming. Some of the reported gold and gold districts are included as far back as 1850.
The first report of gold in California was published in Spain in 1510. California was believed to be an island north of Mexico where gold and precious stones were abundant. Gold was actually mined in California as early as the late 18th century but the "rush" did not begin until the discovery at Sutters Mill in 1848.
Rock and Gem collecting in California is virtually unlimited as illustrated by the key symbols on each USGS map section. A few counties that host exciting deposits are as follows: Siskiyou, Trinity, Tehama and Plumas.
The early maps included in this publication were located in various archival collections. The primary sources were the National Archives and the California State Library. The U.S. Geological Survey supplied the featured modern map. The design is planietric for clarity.
Map identifies locations of: gold and silver, actinolite, agate, amazonite, amethyst, apatite, apache tears, argonite, azurite, beryl, calcite, carnelian, chalcedony, chert, chrysocolla, epidote, feldspar, flourite, fossils, garnet, geodes, hematite, jade, jasper, kyanite, malachite, obsidian, opal, orthoclase, petrified wood, psilomelane, pyrite, quartz, rhondonite, rhyolite, serpentine, topaz, travertine, tourmaline, turquoise, and wollastonite.
