The Arkenstone Heads West!

Our Spring West Coast Road Show is coming up fast, and we've enjoyed our annual San Fran trips over the last decade. This year, we're adding LA to our list, too. We hope to see you for minerals and light bites.  Please make sure to let us know if you're looking for anything specific, so we can pack with you in mind! This is also a great opportunity for us to hand-deliver specimens to clients who might be interested in delicate species that might be concerning to ship, as well.

Rare Earth: Crystalline Treasures

Rare Earth: Crystalline Treasures, ran through September 5th, 2022 at the Santa Barbara Museum of Natural History and featured more than 200 spectacular mineral specimens from around the world. Many of these were on loan from the renowned collector and mineral dealer, Dr. Rob Lavinsky. The exhibit was uniquely interwoven with various themes and stories that make inspirational connections between architectural design & earth materials, art+science+culture, carvings and illustrations, striking color, fanciful formations, and a few cases at the end that took a deeper dive into crystal form.

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.
