Triphylite

Triphylite is the iron end member of the Lithiophilite-Triphylite Series and isostructural with olivine. It is a lithium iron phosphate. It is usually massive, but it rarely forms greenish-gray to dark brown, resinous to vitreous, orthorhombic, stout prismatic, translucent crystals with rough faces. It was named in 1834 by Johann Nepomuk von Fuchs from the Greek word, "tria", (threefold), and "phylon", (family), because it was thought to contain three cations (Fe, Li, Mn). The type locality for triphylite is Hennenkobel mine, Rabenstein, Zwiesel, Lower Bavaria, Bavaria, Germany. Triphylite occurs as a primary mineral in granite pegmatites; it is often completely altered to a variety of secondary phosphates. Some notable localities include: Newry, Oxford Co., and Estes quarry, Cumberland Co., both in Maine, USA; the Palermo No.1 mine, Grafton Co., and Newport, Sullivan Co., in New Hampshire, USA; the Tip Top and Bull Moose mines in Custer Co., and at Keystone, Pennington Co., all of South Dakota, USA. Other world-wide regions where Li pegmatites occur include: Galileia region, Minas Gerais, Brazil. Bohemia, Czech Republic; Bavaria, Germany; Haute-Vienne dept., France; Triphylite occurs less commonly in pegmatites of Sweden and Bolivia.

You can buy these rare greenish-gray crystals online from The Arkenstone, www.iRocks.com to add fine mineral specimens to your collection.

Collector Profile: Dr. Erika Pohl-Stroher

Dr. Erika Pohl-Ströher collected the minerals in her collection over a period of more than 60 years. The specimens are arranged according to geographical regions. Considering that Dr. Pohl-Ströher had no intention of exhibiting her mineral collection and therefore did not make a conscious effort to ensure that she obtained specimens from all over the world, she has succeeded remarkably well in setting up an extensive, comprehensive and magnificent collection that includes minerals from every continent.

Why “Collector Gems” are Enchanting

Besides their inherent beauty, gem collections are appealing for their scientific information. Collectors can learn much about a mineral’s chemical composition and geological origins from a gem’s size, color and clarity. Each of the stones in the Arkenstone auction is a true mineralogical wonder—not just in the geological sense but also as a representative of the species itself.

The Art of Collecting

The team at The Arkenstone has been busy with our recent collaboration with the Santa Barbara Museum of Natural History on our RARE EARTH installation, bringing together specimens from the museum, Dr. Lavinsky's personal collection, UCSB's Woodhouse collection, and private collectors. With permission from museum president Luke J. Swetland, we're sharing a bit of a recent article he wrote about his father-in-law (and Arkenstone customer) David Byers.

Photo Atlas of Mineral Pseudomorphism

We just received notice that Photo Atlas of Mineral Pseudomorphism will be pulled from the Elsevier publication list due to plagiarism in the main introduction of the text. Intellectual scholarship demands integrity, both of which I hold in the utmost respect. I assisted with photos for the books, and related captions for those photos, and in appreciation of this assistance, I was listed as one of the authors on the publication for this narrow scope of contribution. The portions of the text under scrutiny for plagiarism are from the main text of the book, which were outside the scope of my contribution.

Rare Earth: Santa Barbara

Far more than a dazzling display of gems and minerals, Rare Earth tells the story of how we can value the natural world in a new light.  Copper may be worth a few dollars per pound, but a beautiful piece in its (remarkable) natural form is worth far more than that.  The question is why? We humans inherently assign value to beautiful things above and beyond their utility. It’s why we value impressive minerals like these higher than their price as a mere commodity. Whether it’s a mineral, a tree, or an ecosystem, viewing nature purely in terms of “price per pound” undervalues the resource and deep down, we know it. The minerals and crystals you see here are treasures in their own right, worthy of being displayed (and valued) like any other fine art.

Rare Earth: The Art and Science of Chinese Stones

Collecting rocks and stone carvings has been popular in China for thousands of years. This tradition is rooted in the philosophical and spiritual inspiration drawn from the artistic beauty of natural stones, such as jade. Unusually-shaped stones called “Scholars rocks” or “Philosopher’s Stones” carved by natural processes have also been long valued in China. Seen as embodiments of the dynamic transformational processes of nature, these stones were also admired for their resemblance to mountains or caves, particularly the magical peaks and subterranean paradises believed to be inhabited by immortal beings.
