“liquid-like magnetic flow” found in the mineral Herbertsmithite

Quantum Spin Liquid, a third type of magnetism, was demonstrated in December of 2012 by a team at MIT, in the form of synthetic herbertsmithite. Herbertsmithite is believed to be a two-dimensional quantum spin liquid: a solid material whose atomic spins continue to have motion, even at absolute zero temperature. This exciting research has potential to improve technology, another wonderful scientific advance related to the study of mineralogy. While this form of magnetism is limited to the pure synthetic herbertsmithite, the minerals found in nature are quite interesting in their own right.

We noticed a beautiful example of this rare mineral available on eBay by the seller MineralMan999. This sample shows some big crystals for the typical material.

This uncommon Copper Zinc Hydroxide Chloride named to honor Dr. G. F. Herbert Smith (1872-1953) of the Natural History Museum, London, England, who discovered the mineral paratacamite.

The blog “Nanoscale Views”, written by Douglas Natelson, had the best article about understanding quantum spin liquids in a easy to digest fashion. On the subject of the experiments,

So what did the experimenters do? They grew large, very pure single crystals of herbertsmithite, and fired neutrons at them. Knowing the energies and momenta of the incident neutrons, and measuring the energies and momenta of the scattered neutrons, they were able to map out the properties of the excitations, showing that they really do look like what one expects for a quantum spin liquid.

Glenn Rhein’s Amazing Mineral Discovery in Amity New York

During the Tucson Gem, Rock and Mineral show, we met up with Hershel Friedman to discuss our joint workings on the New York/New Jersey Mineral show exhibit organization. That is, the two of us have selected people to put in collections of minerals from New York, New Jersey, Pennsylvania, Vermont, Connecticut and Massachusetts.

While we were going over this subject, we got to talk about how excited we were for Glenn Rhein to show off his mineral finds from his property in Amity, New York. Huge Scapolite crystals, Spinel and all sorts of wild things are being found and will be on display at the NY/NJ show in April 2013.

This video documents the recent discovery of new minerals from Glenn Rhein in the classic locality of Amity, New York, near Warwick. Glenn discovers amazing crystals while excavating on his property, and reaches out to the mineral community for help in figuring out what they are. Glenn then becomes an expert in the deposit and starts finding amazing minerals. Produced and documented by Hershel Friedman of Minerals.net, and filmed by Mark Gilden of Rombus Digital.

Great Video showing the Amazing Finds by Glenn Rheim in Upstate New York!

We hope you enjoyed that video, be sure to share it with your friends. It would even make a great video to show your rock club next time a speaker is unavailable! Thanks to Minerals.net for making this video and promoting a great story! We are looking forward to more videos from minerals.net

Thanks for visiting Wheretofindrocks.com!

Visiting the Tucson Gem and Mineral Show with the Staff from the Los Angeles Natural History Museum

Tucson Rock and Gem time again, from the end of January until well into the month of February tens of thousands of people involved in minerals, rocks and gemstones flock to Tucson for the annual three weeks of trade shows. During this time the buyers and the sellers need to be housed, fed, and entertained, in addition to the countless hours everyone spends going from one show to another, visiting with friends and going to dinner parties, it is a whole world apart for many individuals in this line of work.

Several people post updates about the Tucson show, like Jolyon Ralph of MinDat.org or John Veevaert of MineralShows.com.

The set of show reports we like the best are the ones from the ladies of the Los Angeles Natural History Museum.

Assoc. Curator Eloise Gaillou, work-study student Caroline Im and Collections manager Alyssa Morgan of the LANHM 2013

In these three blog entries, Elouise, Caroline and Alyssa share with the general public the life of three los angeles museum workers during the Tucson show. Though, I am pretty sure no mention of the cramped sleeping quarters are mentioned.

The first report is on the AGTA and GJX gem shows

This is the bracelet I’d do terrible things for. Red Beryl and Montana Sapphires. Ouch.

The next blog entry is about the various mineral shows around the Tucson area, from the Inn Suites (Hotel Tucson) to Riverpark and onwards to some of the more…less visited areas of the Tucson Gem Show.

Roy Foerster, donating a flat of Pyrite crystals the LANHM

There were neat pyrites from Merelani, Tanzania, with interesting morphologies. Roy Foerster, Gem and Mineral Council Treasurer bought us a flat of them. Thanks Roy!!

Then, finally, the BIG show, the Tucson Gem and Mineral Society Show at the Convention Center, which caps off the whole event. A behind the scenes look at one of the important parts that makes the TGMS so legendary, the display cases.

Not to brag or anything, but you KNOW my team here in LA walked away with the GRAND PRIZE for professional educational exhibits

Los Angeles NHM Tucson Gem Show Exhibit 2013

So, while other show reports talk about what minerals are new, why prices are so high and so forth, these reports give you a much better look into the lives of the professionals who make Tucson their home, for a large percentage of their total lives, in the month of February.

The Fundamentals of Mining for Gemstones and Mineral Specimens

The Fundamentals of Mining for Gemstones and Mineral Specimens
By Jim Clanin

Published in January of 2013, just in time for the Tucson Gem and Mineral Show, this will certainly be a hot seller, as readers get to thumb through the 400 page book full of bold colorful pictures of minerals, mining, graphics and a well presented layout overall.

Book Cover of The Fundamentals of Gemstones and Mineral Specimens
Fresh from the printer on January 15th 2013, you can purchase a copy directly from FortySevenPress at the bottom of this article.

The glossy full color, hardcover book resembles a textbook and well compared, as the text inside details with first hand knowledge the vast majority of information someone interested in most forms of mining, hard rock and alluvial. Twelve chapters present technical information, from geology of gem deposits to tips for buying and mining in developing countries. The book details machinery used, safety equipment, haulage, ventilation, in rich detail, with plenty of illustrations and photos to go along with the text. A modern day replacement for the classic “Blaster’s Handbook”, this text gives you plenty of information on proper modern day usage of explosives in mining, along with a chapter devoted to MSHA, Mine Safety & Health Administration and the ATF&E. The book has a chapter that takes the reader from the removal of the mineral in the pocket of the mine to the final marketing of the specimens at a major mineral show.

A Sample Page of The Fundamentals of Mining for Gemstones
This is a sample page from the book, available for purchase at the link below.

The second half of the book is divided into eight sections, each devoted to a profile of a mining operation. You are taken around the world in search of Rubies, Tourmaline and Fluorite. Some of the sections are short, just a few pages and photos, while two of them, namely, the Cryo-Genie and the Rogerly Fluorite Mine, are full length stories, complete with day to day happenings and amazing behind the scenes photos. I particularly enjoyed those two chapters as they captured unique times at both mines. The Cryo-Genie was producing the famous BAT pocket, containing what would become the major museum pieces, while the Rogerly chapter captured the year after the major specimen mining began in 1999.

The book is worth it for if nothing else, publishing this photo!

We have this book available for direct shipping to any US resident for $62.95, shipped priority mail.

The iconic Steamboat Tourmaline – an American Treasure

In 1907 the famous Steamboat Tourmaline was unearthed by Frank Barlow Schuyler in San Diego County in a rich tourmaline-bearing pocket zone in the mine which was named the Tourmaline King. It was then sold by Schuyler to Washington A. Roebling and it is now housed at the Smithsonian Institution.

Although the Steamboat Tourmaline is well known, few people are aware of its discovering in California by Schuyler. Schuyler was born on August 20, 1872 in Falls City, Nebraska. Schuyler took up the same work as his father, a machinist and manufacturer of mechanical tools and married his wife Ella S. Libby in San Luis Rey, California in November of 1894. Then in 1897, their only son Gerald Barlow Schuyler was born.

Schuyler teamed up with D.G. Harrington of Oceanside, California in March of 1903. The pair was exploring the Pala Chief Mountains in San Diego County for pegmatites. During their exploration, they stumbled upon a huge tourmaline deposit which they named the Tourmaline King Mine. Schuyler and Harrington began to construct an underground drift into the pegmatite directly under their surface discovery in 1904. About 60 feet underground and a few years later, the team found a gigantic tourmaline crystal-filled pocket. It extended almost 30 feet in length, about 10 feet wide and was uninterrupted for about 30 feet down dip. This single zone produced around 8 tons of pink tourmaline. The bulk of this discovery was sold to the Imperial Chinese government for a considerable price of $187.50 per pound.

Schuyler presented and sold his tourmaline gems that he had extracted from the Tourmaline King Mine, at the 1915 Panama Pacific international Exposition in San Francisco. His slogan during the exposition was “wear a tourmaline for luck”. Schuyler also sold and presented other specimens that he had extracted from the Tourmaline King Mine in San Diego County at the exposition.

Robert Max Wilke, a California mineral dealer, purchased the patent grant deed from Schuyler in 1916 for rights to the Tourmaline King Mine so he could work it himself. This purchase by Wilke is the end of Schuyler’s involvement with the Tourmaline King Mine. Wilke went on to discover large amounts of lepidolite, morganite, tourmaline and kunzite at the mine. Wilke eventually abandoned the Tourmaline King Mine in 1922.
