Houston Fine Mineral Show: April 30 – May 2, 2010

The Houston Fine Mineral Show is an exclusive show highlighting over 50 top mineral dealers. Pala International’s Bill Larson and Will Larson will be attending this year’s show.

Event: Houston Fine Mineral Show
When: April 30 – May 2, 2010
Where: Embassy Suites Hotel, Houston, TX

Visit the Houston Museum of Natural Science

The Houston Fine Mineral Show allows us to promote one of our favorite museums and its stellar collection of mineral specimens: the Houston Museum of Natural Science. The museum’s Cullen Hall of Gems and Minerals “houses the world’s finest display-quality collection of gems and minerals,” according to its own website—and that’s no exaggeration. The hall’s display cases employ fiber-optic lighting and offer 360-degree views of more than 750 specimens that simply must not be forgotten while you’re in H-town.

See our story on a visit to the Cullen Hall by Pala’s Gabrièl Mattice in 2006; the snapshots she took will give a taste of what’s in store. And the gemstone enthusiast will want to catch the special exhibit “Fabergé: Imperial Jeweler to the Tsars,” which features the McFerrin Collection. [back to top]

Tourmaline from Nuristan, Gemstones from Pakistan

A follow-up on our last edition’s story

In our previous edition of Pala Mineralis, we featured a photo essay, “Tourmaline Mining in Afghanistan,” contributed by a correspondent in southwestern Asia.

Coincidentally, via a mutual friend, we received a reply on that story from another correspondent, in Pakistan, who we hadn’t heard from in some time. (He had last notified us about a December 2005 avalanche in a peridot-mining region of Kohistan, in the North West Frontier Province border region and had commented on the state of the gemstone industry in Pakistan at the time.)

From Paprok, Nuristan. This tourmaline from Afghanistan consists of four prominent attached crystals. Good luster with glassy terminations. It measures 6.6 x 4 x 2.4 cm. Inventory #18086. (Photo: John McLean)

Read his remarks on the tourmaline mining in the general area of the Mawi pegmatites in Nuristan Province.

And Pakistan?

Turning to another subject, and another country, we asked our contributor for a new assessment of Pakistan’s gem and jewelry industry. Four years ago, he’d admitted to being an optimist, but in the face of a reality that called for skepticism. Now, things are “still a little ‘rough’ but improving.” (Select the link above for the full story...)

From Shigar Valley, Baltistan. This specimen features a gemmy upper half and measures 11.4 x 2.6 x 2.3 cm. Inventory #18087. (Photo: John McLean)

“It’s all about the people…”

Cornell collaboration will involve Pala’s Bill Larson

We recently caught up with Elise Skalwold, gemological curator at Cornell University. Our readers may recall “Viking Compass and the Usambara Effect,” which we cherry-picked from her website last June. Well, when she’s not festooning that website with streaming video of growing hydrothermal sapphire in a diamond anvil cell, for the past year she’s been working on a gem and mineral project that remains under wraps. When the curtain is pulled back, however, it will involve among other things a publication featuring photographs by Jeff Scovil, and will include a foreword by Pala’s Bill Larson, who also has kindly provided ad hoc advice along the way.

Both originate from the Wah Wah Mountains, Beaver County, Utah (Cornell University gem and mineral collection). This appears in John S. White’s “U.S. Gemstones: An Overview” in the January/February issue of Rocks & Minerals. (Photo: Jeff Scovil)

Leaving the mystery aside, we were taken by Elise’s description of the work involved in the ongoing project—a series of collaborative connections. “The context is gems and minerals,” she tells us, “but it is all about the people and the process.” She is honored to collaborate and be co-author with her dear friend and leader of the project, Cornell’s William Bassett, professor emeritus of geological sciences, and recipient of the Mineralogical Society of America’s highest award, the Roebling Medal. Oh, and “one of the pioneers of diamond anvil cell high pressure research,” she reminds us. But then you would have gathered that when you visited the link above.

“Elephant” Emerald Unearthed in Zambia

The “elephant” has entered the room. A massive 6,225-carat rough emerald crystal has been pulled out of the Kagem mine in Zambia. The local Bemba people named the oversized green jewel “Insofu,” which translates as “elephant.” This remarkable specimen was found on February 5 and announced by the gemstone producer Gemfields. Evaluation of the true quality of this piece has not been released, but even from the simple picture below, one can see the strong color and high clarity. No doubt we will be seeing some mammoth faceted emeralds out of this very gemmy-looking piece of rough.

The “elephant” was named for its size, but also in honor of the World Land Trust’s “Wild Lands Elephant Corridor Project.” Promotion of the project will include the creation of “a bespoke collection of emerald jewellery, designed and created by the very best jewellers from around the world,” according to this International Colored Gemstone Association news item. See also this compelling preview of a forthcoming documentary on Asian elephants. (Photo courtesy Gemfields)

Zambia has become an important source for emeralds as the world’s thirst for these green jewels grows. Other major producers include Colombia and Brazil, which have produced some record-settling emeralds as well. Colombia unearthed a 7,025-carat emerald crystal that actually held the record, but Brazil supposedly found the largest uncut emerald in 1974 that weighed 86,136 carats, according to The Daily Telegraph (UK) and Mindat.

For an overview of gemstone mining in Zambia, see this 2007 briefing paper prepared by the NGO groundWork.

Ron Ringsrud on the Elephant and El Itoco

Our friend Ron Ringsrud, author of Emeralds, A Passionate Guide, had this reaction to the Zambian find: “I am so impressed with the transparency of the ‘Elephant Emerald.’ It is astounding. It reminds me of the gem-quality transparency of the Itoco emerald.”

Ron should know; he facilitated the Itoco’s display last year at Southern California museums, as we reported. [back to top]

Mineral Artists: Hildegard Könighofer and Gamini Ratnavira

Among several mineral portraitists to be featured at Tucson

The Tucson shows this year will offer exhibitions and a panel presentation by prominent mineral artists.

Westward Look will host the panel on Sunday, February 7. Panelists Eberhard Equit, Hildegard Könighofer, and Susan Robinson will join moderator Wendell Wilson for an overview of their work. The traditional pre-event cocktail hour will allow attendees to browse the work of several other artists, in a concurrent exhibition to feature Chris Hughes, Gail Spann, Fred Wilda, Gamini Ratnavira, Steve Sorrel, Brandy Naugle, Sarah Sudowski.

The Tucson Gem and Mineral Show exhibition of the four panelists’ work takes place February 11–14. According to the show brochure, the artists will “display some of their most impressive work next to the stunning gems and minerals that inspired them” and will spend time there to meet attendees.

We preview the work of two artists, Hildegard Könighofer and Gamini Ratnavira.

Hildegard Könighofer

A participant in both the Westward Look panel and TGMS exhibition, mineral portraitist Hildegard Könighofer will celebrate at Tucson the publication of a new book, The Mineral Art of Hildegard Könighofer. Accompanying 149 pages of the artist’s paintings are nine articles authored by twelve contributors on topics such as “Science vs Aesthetics,” “Appropriation and Reproduction,” and examinations of notable localities. The articles are presented in German and English, with German captions.

Two editions are available, but are likely to go quickly. At left is the gray-leather limited edition, which includes a slipcase. The book is offered exclusively in the U.S. by BlueCap Productions.

Austrian artist Hildegard Könighofer, along with her partner Dietmar Jakely (a contributor to the new book), is a mineral collector, and has illustrated her own specimens as well as those of the Naturhistorisches Museum Vienna, Landesmuseum Joanneum Graz, and many prominent local collections, according to this Mineralogical Record profile. Like Gamini Ratnavira, Könighofer also paints botanical subjects.
 

Gamini Ratnavira

Sri Lankan Gamini Ratnavira, whose life and work we profiled in December, is a close, close friend to Pala International, and in fact has his art studio and bird sanctuary on the Pala grounds. His paintings have focused on tropical plants and wildlife, but he has branched out into the world of mineral art with the help of Bill Larson’s choice subjects. He will be in Tucson, joining the group of mineral artists at this year’s Westward Look Show on Sunday evening.

Growing up near the Sri Lankan mines of Ratnapura (“city of gems”), Gamini developed an eye and appreciation for minerals and began painting tourmalines in the 1990s for a forthcoming book by Bill Larson. (Sixty out of a projected 100 of the paintings have been completed.) Additionally Gamini has painted dozens of originals for the renowned mineral dealer Dr. Rob Lavinsky and appears annually at the Tucson Gem and Mineral show. Internationally collected, his artwork can be visited at his website and at his gallery on BlueCap Productions.

Palaminerals.com

Pala International to debut website devoted to mineral specimens

Pala International will soon debut a new website, for the mineral devotee: Palaminerals.com. The website aims to offer the existing catalog (currently available from CollectorFineJewelry.com) in an updated format and with enhanced search capability.

We’ll notify both groups of our subscribers—minerals and gems—just as soon as the website goes online.

Will Larson, webmaster David Hughes, and Fallbrook IT pros Stephen Calia and Brent Dussia have guided the project through design and scripting phases. Features that users have come to rely on, via the sister site, Palagems.com, will be integrated into the site, including Mineral News from Pala International, which receives its new title and masthead, Pala Mineralis.

Why “Pala Mineralis”?

The literature of mineralogy predates the printing press of Johannes Gutenberg, himself a goldsmith and gem-cutter. Medieval mineralogical works, such as those by 13th century polymath Albertus Magnus, were some of the earliest to see the transition from manuscript to printed page, with his De Mineralibus Libri being published in 1476—only twenty years after the famous 42-line Bible. As stated in a bibliography by the late Curtis P. Schuh:

With Albertus Magnus' mineralogy, the study of minerals begins to emerge from its embryonic period into a full fledged science. The tradition of magical and curative powers in gems still permeates the text, but one feels the author fighting the superstitions of the ancient beliefs, and seeing the world in a new, more skeptical and practical view.

Although the coming renaissance would lead, as suggested above, to the Age of Reason, even Isaac Newton, as a scientist of his day, delved into alchemy and other esoteric investigations. And while the great age of the illuminated manuscript had since passed, illustrated manuscripts continued to be produced. One such work—perhaps at first glance more compelling for its arcane subject matter than its awkward imagery—is Cabala mineralis, a curious ~17th century alchemical treatise.

Alchemy was (is) concerned with investigation and, of course, transformation. And so it is both the curiosity-compelling and transformative power of nature’s creations, as we behold them, to which we pay homage in our echoing—rhyming, twinning—of a long forgotten alchemical text. Pala Mineralis. (Dulce et decorum est.)

The Virtual Museum beckons…

If the above discussion generates a jones for musty mineralogical tomes, a return visit to the Virtual Museum is in order.

Big Al. Yes, the Virtual Museum has a copy of De Mineralibus Libri; colophon: Patavii, Petrus Maufer for Antonius de Albricis, 20 September 1476.

It’s been some time since we looked at the Virtual Museum of the History of Mineralogy. According to the December 2009 Museum newsletter, the most recent additions to the collections have been in the categories most viewed by visitors to the virtual displays: goniometers and crystal models.

Since mid-summer, nine of the instruments have been added, as well as a mid-19th century set of twinned feldspar crystal models—a gift from a prominent Berlin collector to a prominent Berlin crystallographer. Also added was a lovely set of indicators for specific gravity measurement, circa late 19th century.

Earlier, during the first six months of 2009, the museum’s curators Paul Tambuyser and Claude Hootelé nearly doubled the size of the book collection, adding two dozen a month. View the images from Christian Ernst Wünsch’s 1781 Briefwechsel über die Naturprodukte... and then take me to task for my remarks above about “awkward” illustrations. The stuff is glorious. As are the other volumes featuring illustrations (highlighted in the museum’s July 2009 newsletter). These surely will accelerate anticipation of this month’s Mineral Artists Show at Tucson.     — David Hughes

The San Diego Natural History Museum is opening an exciting new exhibit for all those gem lovers out there. “All that Glitters: The Splendor & Science of Gems and Minerals” will include mineral specimens, faceted gemstones, and designer jewelry. It tells the story from the formation of gems within the Earth to Man’s creations employing all the wonderful gem materials. The exhibit will appropriately focus on the fascinating array of gems and minerals found in San Diego County, along with a wide variety from major gem producing regions around the Earth.

Over 100 gems and mineral specimens will be provided by Pala International. Prominent names in the industry like Tiffany & Co., Van Cleef & Arpels, and Cartier will provide a wide range of original jewelry pieces. Harvard University, the Smithsonian, the American Museum of Natural History, and the Museum of Fine Arts in Boston all will be adding to the extravaganza with more jewels and mineral specimens.

The exhibit opens May 15, 2010 and is scheduled to run through April 2012. “In addition to demonstrating the ‘splendor and science of gems and minerals,’ All That Glitters will have a playful side,” says Exhibition Curator and Graduate Gemologist Elise B. Misiorowski. “Jewels and carvings incorporating natural-history themes will give children as well as adults delightful surprises to hunt for. How many jeweled butterflies, birds, and flowers can you find? Which case contains the Faberge carved pig with diamond eyes?”

See the exhibition website for a look at the efforts underway to construct display installations as well as some of the pieces that will be included in the exhibition. The show’s inaugural week will culminate with the All That Glitters Gala. “The All That Glitters exhibition will seduce visitors with the beauty of these precious objects and fascinate them with the science of their formation, and the Gala will delight revelers with exquisite food, beautiful ambience and fantastic entertainment,” said Ellen Zinn, museum board member and Gala Chair, according to a press release containing more Gala details.

Mineralogical Almanac to Feature Bill Larson Article

Russian journal’s next edition planned for Tucson

In December, we featured Will The Younger’s report on the phenomenon of Mineralientage München. This month, another world-class venue, Tucson, will feature the appearance of the elder Larson’s take on the Munich show, courtesy of the Russian journal, Mineralogical Almanac. If all goes as planned, the Almanac’s Ludmila Cheshko and Michael Leybov will have copies in tow, at the show.

We’ve seen a proof of the nicely illustrated article, which shines the spotlight on the Indian Exposition, the centerpiece of the 2009 Munich show. Munich this year featured some colossal mineral specimens. “It’s amazing to see the many tons of relatively perfect Indian mineral specimens which would be somewhat common if not for their enormous size,” Larson writes. “There are Stilbites, Quartzes, Quartz geodes, Calcites, Apophyllite in large formations rarely seen.”

As we stressed in our pre-show news item in October, the Munich show has much to offer fans of colored gemstones. A companion article by Jacques Touret, of Paris’s Musée de Minéralogie–Ecole des Mines, includes a page of faceted and sculpted beauties: luscious Mahenge spinels, 25–40 carats, and two aquamarine carvings—a 15–20-cm gold-beaked, sapphire-sighted falcon perched on a ruby-topped pedestal of gold and jasper, and a “frozen” aquamarine, which, at 15,950 carats, surely melted the hearts of its viewers.
