Azurites-Beautiful Milpillas Finds
Azurites-Beautiful Milpillas Finds
Milpillas is now the world’s finest and most productive source ever of Azurite, without a doubt. We have pursued this mine since its first trickle of material in 2007, and continue to have a strong buying presence there.
Chinese Scheelites and Barytes
Chinese Scheelites and Barytes
Jan 21, 2015 - An update of beautiful and unusual new China finds: scheelites from a new find at the most famous mine in China, which although mined economically for tungsten has produced few good scheelites and two-toned barite crystals from Jiangxi.

Jan 19, 2015 - Rich blue plumbogummites are historically quite rare. Chinese mines have been producing these beautiful specimens recently using artisanal mining methods.
Chinese Purple and Green Combo Fluorites
Chinese Purple and Green Combo Fluorites
Fluorite on fluorite, showing a contrast of color and form that is simply unexpected, from an old commercial fluorspar mine in China. However, over many years of mining here, nobody had EVER seen anything like these pockets of curved purple crystals atop either massive or crystallized green fluorite matrix.
Vivid Green Demantoids
Vivid Green Demantoids
These deep green demantoid crystals reach 4 cm in size and seem to be the only species in their pockets. The best of them look like green disco balls. These appear to be artisanally mined by a few small groups of collectors.
Alkali-Rich Beryls
Alkali-Rich Beryls

July 13, 2014 - Alkali-rich beryls are an unusual beryl variety with strange morphology, found only a few other places. This update presents a significant amount of the high-graded material from the pocket found in mid-2012, which is the first reported find of this beryl in Pakistan. The specimens are truly unique, and fascinating crystals!

Peruvian Native Arsenic Specimens
Peruvian Native Arsenic Specimens
Nov. 9, 2014 - From a large but highly unusual find of pure arsenic in this historic mine, found in summer of 2013. Although we have seen many specimens from this mine, including fine orpiment, I had not previously seen pure native arsenic.

Moroccan Vanadinites
Moroccan Vanadinites
Aug 27, 2014 - These aesthetic tabular vanadinites from Mibladen, Morocco were hiding away in our warehouse since 2009. Rediscovered 5 years later, we're putting them up for sale at the old prices!

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.
