Passing…
Gem Dealer Dana Schorr Dies at 63
It is with a heavy heart that we announce the passing of our longtime friend and fellow gem dealer Dana Schorr.
Dana passed away from complications from a massive heart attack on August 5. Dana will always be remembered as a friend with a true passion for this industry. He loved gemstones and more importantly, he loved people. His infectious smile and hearty laugh were always accompanied by a twinkle in his eye. He will be sorely missed by all of us.
Rest in peace, Dana.
Your loving friends at Pala International
Dana Schorr
Dana Schorr was born in 1952 in Santa Monica, California, and his formative years were spent in New York and Santa Barbara. He was known to be an activist in the gemstone community, but his rabble-rousing began early, having involved himself in Students for a Democratic Society, according to a tribute by his good friend Richard W. Hughes. It was his political involvement as a propagandist that drew him into the printing field, and from there he branched out into gems in the 1980s after selling some stones for a friend, at a profit, according to an obituary by National Jeweler.
For more than seven years, Dana was a partner in an office in Arusha, Tanzania, trading in tanzanite, and having a cutting factory in Sri Lanka with the same partner. His work in Tanzania as well as travels to many gemstone-producing countries put him in touch with artisanal miners, who he then championed, refusing to defer to what he felt were wrong-headed attempts at industry ethics reforms. He told me that he suspected the gemstone industry might have been made a guinea pig for regulation that could be applied to other fields. (For details on Dana's mission, see January's "Ethics Heckling: Digging Deeper, Sustainably Speaking.") Dana was due a follow-up call from me on this subject, but alas, that chance is missed. Missed also will be the delight he obviously took in life even as he examined the underbelly of our nature.
In addition to Dana's interest in gemstones, he was a music enthusiast, being a member of the Santa Barbara Jazz Society, as well as an avid dancer. And his name can be found in the agenda of the Santa Barbara City Council. He is survived by his mother Emmy, sister Wendy, and brother-in-law Roger Lebow. Expressions of condolence can be sent to The Schorr Family, 197 N. Mountain Trail, Sierra Madre, CA 91024.

Victoria & Albert Museum: India & Burma
To celebrate the twenty-fifth anniversary of the opening of its Nehru Gallery, which displays objects from the Victoria & Albert Museum's important South Asia collection, the V&A is in the midst of an India Festival. Fabrics, jewels, photographs, paintings and the performing arts all are represented. We look at two of the offerings that should interest gemstone lovers.
Captain Linnaeus Tripe: Photographer of
India and Burma, 1852–1860
Linnaeus Tripe (1822–1902) joined the East India Company Army in the late 1930s, returning in 1850 to Britain, where he took up photography in 1852. He returned to south India in June 1854, being stationed in Bangalore. His first photographs of India were taken while he was on leave that December. Photos of previously unphotographed temples were exhibited in February 1855, in a juried show that brought him acclaim and the attention of the Madras Photographic Society. In June Tripe was sent to Burma, where he faced the challenge of the heat melting the wax on his negatives as well as prostrating his assistants. He returned to Madras, becoming its government's official photographer in December of 1857, but by mid-1859, funding ran out. Tripe's technique is summed up below, from the V&A news release for its exhibition, which runs through October 11, 2015. (See more about his technique here.)
Tripe's photographs are technically complex and he is known for his innovative precision with the camera, paying close attention to both his composition and its realisation when printing. To evoke atmospheric effects Tripe retouched most of his negatives by applying pigment in thin layers and included in the exhibition are a selection of waxed-paper negatives that reveal these working methods. Also on display will be a segment of a panoramic scroll showing the inscriptions around the base of the Great Pagoda temple in Tanjore. Composed of more than 20 prints assembled and mounted onto a long canvas scroll, it is now regarded as a considerable technical achievement, given the physical and climatic conditions of the time.
Bejewelled Treasures: The Al Thani Collection
Last fall, the Al Thani Collection visited the Metropolitan Museum of Art; this fall it has a stop at the V&A, November 21, 2015 through March 28, 2016. Even if you saw it in New York, you'll want to catch it in London, because forty more objects are added to MoMA's previous sixty. The jewels come from the private collection of Sheikh Hamad bin Abdullah Al-Thani.
The V&A exhibition is divided into sections titled The Treasury (late 16th to early 17th century Mughal creations featuring stones of size), The Court (commissioned pieces whose influence endures), Enamel (bringing enamel work out of the shadow of bejewelled pieces), The Age of Transition (Indian jewelry influenced by European designs), Modernity (ditto, but in reverse), andContemporary Masters (a mash-up). Bhagat, a mash-up master (see above image) is interviewed in one of three films that were commissioned for this exhibition.
Road Show: Inspiring Beauty
Editor's Note: While the subject of this article does not deal with gemstones specifically, it does concern itself with the issue of African Americans' relationship with fashion in general and, by inference, with the larger world from which Black people had been prohibited in the first half of the twentieth century—a legacy that lingers.
In 1946, nine years before he would become editor of The Nation magazine, Carey McWilliams shocked the likes of Minneapolis mayor Hubert Humphrey by calling the city "the capitol [sic] of anti-semitism in the United States," in the pages of Common Ground, a periodical that had introduced the term ethnicity as a less-charged alternative to race. Indeed, the next year, even a member of the Mayor's Council on Human Rights—a realtor by trade—was found to have discriminated against Jews wanting to buy a home in the suburb of St. Louis Park. Ironically, that same suburb later would have a significant Jewish population, as depicted in Joel and Ethan Coen's feature film A Serious Man (2009).
The fact that Minnesota, as early as 1888, had enacted a ban on discrimination in public accommodations based on race or color did not keep restaurants—and even a summer camp for the blind—from barring African Americans in 1947. In 1951, Black journalist Carl T. Rowan wrote a remarkable series of articles for the Minneapolis Tribune as he traveled the Jim Crow South, yet upon his return he would admit, "The fear of physical harm lessens" when crossing the Mason-Dixon line. "But the step across the boundary really is a barely discernible transition from flagrant displays of bigotry to the more subtle, surreptitious variety of prejudices." Despite this, and despite the fact that the non-white population of Minneapolis comprised less than two percent of its half a million inhabitants, the city had a vibrant African American community, with its own newspaper, the Minneapolis Spokesman, which gave voice to several engaging writers.
This, then, is part of the background to a traveling exhibition that just closed yesterday in St. Paul's Minnesota History Center, "Inspiring Beauty: 50 Years of Ebony Fashion Fair." (The show moves on to Detroit; Rochester, New York; Bellevue, Washington; and Washington D.C.) Begun in 1957, Ebony’s fair leapt off the pages of the magazine's existing fashion coverage when Jessie Dent, wife of Dillard University president Albert Dent, suggested the magazine put together a fashion benefit. As of 1976, according to Jet magazine, "the ultimate fashion show tours 154 cities in the U.S. with a dozen dazzling models laden with 200 of the most luxurious creations imaginable." Caption placards in the "Inspiring Beauty" exhibition state that the Fair traveled to more than 180 cities at its height, yet in the early years, the show's directors "faced discrimination from fashion designers, who feared clients' reactions to seeing exclusive designs on black bodies." According to Ebony publisher John H. Johnson, Fair organizers had to "beg, persuade, and threaten [for] the right to buy clothes."
An exhibition news release credits the Fashion Fair with "ultimately help[ing] to redefine the concepts of beauty, style and empowerment for African Americans." The show's curator, Joy Bivins, said, "Fashion was always the draw but the opportunity that the show provided black women to see fantastic fashion on women who looked like them was equally important. On the Ebony Fashion Fair runway, black women were the beauty standard."
In an accompanying video, produced by the Minnesota Historical Society, Lisa Tittle, of the Alpha Kappa Alpha Sorority, one of several Fair hosts, remarks, "There were so many models of color, of all sizes as well." Marvin Roger Anderson, a stagehand for early fairs, says, "The Ebony Fashion Fair represented a certain achievement status of the African American community; African Americans can put on this first-class show."
"Inspiring Beauty" presents nearly one hundred objects such as ensembles, accessories and archival photographs. Themes explored in the exhibition are vision, innovation and power. An accompanying catalog also is available.

Pala’s Featured Stones: Pezzottaites from Madagascar
This month we feature not only one, but two world class pezzottaite pieces from Madagascar. This is a truly rare collectible gem that was only identified in 2003 by Dr. Federico Pezzotta in Madagascar at the Sakavalana Mine. A newcomer to the gem world with extremely intense and saturated colors unlike any other, it is one of nature's rare beauties. Pezzottaite is a cesium (Cs) rich member of the beryl group. Pezzottaite is in the trigonal crystal system, while beryl falls into the hexagonal system.
We just recently picked up the cat's eye pictured above at this summer's Sainte-Marie-aux-Mines show and Pala International's Bill Larson pulled the kite shape out of his personal collection to offer it on the market. Pezzottaite is often included in large sizes, and in the cat's eye those inclusions lined up well enough to create a nice chatoyancy. The faceted gem is huge for the species and represents some of the best color to be found. See more on pezzottaite at Gemdat.org.

GIA Laboratory Bangkok: Lights, Camera, Action
The GIA laboratory Bangkok has had a website makeover, bringing it in line with GIA's main site. In the course of the facelift, the lab has added content, including many streaming videos from its various field research trips. (The lab established a field gemology department in 2008, and we have pointed to its reports over the years.) The most recent posting, "On the Track of Africa Hidden Gems," weaves together footage from expeditions in 2012 and 2014 to Madagascar, Kenya, Tanzania, Zambia and Mozambique. If you were interested in BBC's look at sapphire mining in Madagascar, which we pointed to last month, you'll enjoy "Sapphires from Ilakaka, Madagascar," also based on those two expeditions.
Written reports also abound. Two posted in June discuss ruby synthesis and spinel treatment: "An Analysis of Synthetic Ruby Overgrowth on Corundum" and "Cobalt Diffusion of Natural Spinel." And if you're visiting Bangkok, you can plan around periodic GIA Gemstone Gatherings; those in 2015 have included the film The Italian Jewellers, Jade Nomenclature by Shane McClure, Australian Sapphire by Terrence Coldham, and more.
The Micro-World of Gems & Gemology: A Delicious Blend of Science and Art
By Elise A. Skalwold
The Summer 2015 issue of Gems & Gemology is hot off the press and, simply put, from cover to cover, it is stunning. Since it became large format in 1981, the covers of each and every issue over the years have featured the breathtaking work of famous gem photographers, including nearly exclusively those of Harold and Erica Van Pelt who from 1981 to 2009 graced the covers of 93 issues; a fine tradition which has continued ever since with the work of others such as the celebrated photographer Robert Weldon of GIA.
The current issue marks the third time in the journal's history that the work of photomicrographers has taken its place in this prestigious lineup. More than three decades ago, master photomicrographer John I. Koivula—a pioneer of this specialized art form and of the science of inclusion study itself—had his image of a euhedral spessartine garnet crystal seemingly floating in a quartz universe featured on the cover of the Fall 1981 issue (above left), heralding one of his early articles on photomicrography within: "Photographing Inclusions."
Twenty-two years later, Koivula's phenomenal rendering of a Deer Creek fire agate's micro-features found its way onto the cover of the Spring 2003 issue (above right) containing his now classic article "Photomicrography for Gemologists." As some readers may already know: mineralogist, chemist, and gemologist John I. Koivula is the analytical microscopist at GIA and is a Fellow of the Royal Microscopical Society. In addition to hundreds of articles and peer-reviewed scientific papers, Koivula is author of the book The MicroWorld of Diamonds and co-author of the three-volume set Photoatlas of Inclusions in Gemstones, which features over 5,000 of his unique photomicrographs.
Mentored by Koivula himself, Nathan Renfro makes a grand debut with the third photomicroscopy cover (right): a splendid image of modified trigons on the surface of a Kelsey Lake diamond crystal. Geologist and gemologist Renfro is the analytical manager of the gem identification department and an analytical microscopist in the inclusion research department at GIA in Carlsbad, California.
Following Koivula's earlier publications, which in turn cover advances in techniques and instrumentation over those decades, in this issue Renfro contributes a masterful updated article entitled "Digital Photomicrography for Gemologists." Together with the '81 and '03 issues, this triad will become an enduring reference for professional and budding photomicrographers everywhere. Not only that, the techniques taught within all three will advance microscopy skills at all levels.
As one well-known gemologist/appraiser wrote to this author: "Thanks, Elise, for highlighting this fabulous article by Nathan Renfro, a protégé of John Koivula who, along with Edward J. Gübelin, is a top name in photomicrography of the internal world of gemstones. A study of this article alone is all that is needed to bootstrap one's self to a high level of competence and skill in this wonderfully rewarding, artistic and scientific field of endeavor. Nathan has covered it all, and nothing of significance has been omitted." (Michael D. Cowing, Owner, A. C. Associates)
Nathan Renfro’s photomicrography is no less beautiful nor less scientifically accurate than his great friend and colleague's, but neither does it mimic those of his mentor. Renfro's work is uniquely his own style, and just as Koivula's does, transcends simple recording of gemological features and finds its itself crossing specialties—arguably taking its place in high art itself as the following images from his portfolio attest:
Not stopping there, Nathan Renfro is Lead Editor of an all-new quarterly column along with John Koivula and this author as Contributing Editors: G&G Micro-World. The column features images, techniques and new findings contributed by various authors including those of its Editors. As G&G's Editor-in-Chief Duncan Pay writes in his editorial for this issue: "With this new regular feature, section editors Nathan Renfro, Elise Skalwold, and John Koivula aim to foster the wider appreciation of inclusions and to bolster practicing gemologists' observational skills by providing concise reports accompanied by stunning photomicrographs of specially chosen specimens. The authors invite gemologists to take a closer look at the astounding beauty and variety of inclusions in gems."
The outpouring of positive feedback has been gratifying, including this from a retired lawyer enrolled in GIA's distance program: "Hello Elise, I am so engaged by the Micro-World article and photos in [the] G&G summer issue that I decided to subscribe to get the hard copy issues. While the online downloads are great, I am so impressed by these super cool images that I plan to put the issues out in my living room for guests to peruse. Table top worthy!" (Kimberly Arpaia, owner Arpaia Jewelry)
I am so thrilled by this comment especially. It speaks to the continued need and desire for hardcopy journals, as well as appreciation for an idea John I. Koivula proposed to me nearly two years ago which has finally come to fruition and a warm welcome under Nathan Renfro's leadership.

Lydia Ainsworth's "Rock" Music
Joan La Barbara is a giant in the world of avant-garde music. The "extended vocal techniques" for which she is famous have been featured in her own works as well as those by John Cage, Steve Reich, Philip Glass, Lou Harrison, and even The Living Theatre and Sesame Street. One of La Barbara's students at New York University, Lydia Ainsworth, might not have incorporated voice into her own compositions for film had it not been for La Barbara's encouragement in 2011. That vocal work eventually led to an invitation of Ainsworth to perform that same year at a party; problem is, she had no songs. No stranger to composition, of course, she wrote a couple, and they formed the heart of her 2014 debut pop collection, Right From Real.
Like singer-songwriter Björk, whom Ainsworth counts among her influences, two songs from her album have mineral references. In "Moonstone," she sings in 6/8 time of walking to "the city of jade," facing danger and moving through the dark toward light. The chorus is a recitation of thirty-two names of colored gemstones and minerals. "Malachite" has a single reference to that mineral: black "with veins of green." Its anachronistic chorus—inspired by Verdi's Requiem—announces the demise of the Internet. We're grateful the Net's not dead, since it provided us introduction to Lydia Ainsworth.

Mining Hazards
Two stories about mining in South America caught our eye recently…
Paraiba Plunder
London's Telegraph (and other sources) reported two months ago on a multi-million pound tourmaline mining operation in Paraíba, Brazil's São José da Batalha. Problem is, the mining was conducted illegally, with operators being arrested after a six-year investigation. Six out of eight suspects were nabbed, including a state deputy named João Henrique de Sousa, who was permitted to mine the Paraíba state's famous tourmaline, but who allegedly did not declare the mining output to the national department of mineral production.
After being mined in Paraíba, the stones were moved one state north, to the city of Parelhas in Rio Grande do Norte. There they received licensing illegally before being moved south to the state of Minas Gerais for cutting. Using a network of offshore accounts, the operators sold the stones in Bangkok, Hong Kong, Houston and Las Vegas. Ten million pounds in assets were seized.
Colombia Collision
Meanwhile, in Colombia, the Washington Post reported on August 9 about that country's largest emerald mine, two years after it was bought out by Charles Burgess and his Houston-based Minería Texas Colombia, or MTC. Controlling interest was obtained from "emerald czar" Victor Carranza, who died in April 2013. Carranza was a peace-keeper, but without his protection MTC is seeing its shafts seized by locals.
After reciting the recent history of emerald mining and Carranza's place in it (see our own story from 2012), the Post turns to Burgess, who was a newcomer, and who was married to a Colombian woman by the same archbishop who brokered Carranza's peace deal in 1990. Carranza seemed to think that the outmoded emerald mining could use a modern shot in the arm. Burgess, who had no experience, provided that remedy, but with those changes came resentment. Like the gleaners of Mogok ruby mines, local Colombians had been used to picking over mining waste, but that changed with new mining processing that leaves little left over except a residual resentment. The Post tells of mobs invading the mines. Obviously, a new peacekeeper is needed.
Burma Bits
Jade Jottings
Jade dealers in Mandalay are complaining about a severe slump in sales. Myanmar Times on July 29 quoted traders as saying this was the worst market in years, that jade could not be sold at a profit. And the quality is no good as well. One dealer said he was selling at prices twenty-five percent less than in previous years.
This sentiment echoes that of traders exiting the most recent gemstone emporium, conducted earlier this summer, as reported by Nikkei Asian Review. Jade sales at the emporium were down sixty percent compared with last year. The article blamed two factors: imposition of austerity measures in China that dampen enthusiasm for luxury goods and the seemingly eternal warfare in jade-producing Kachin state.
On the other hand, the pearl emporium, held in conjunction with the gems sale, saw its most successful result in years, according to another July 29 story by Myanmar Times. Ninety-eight percent of the total offering was sold, at $3.3 million. One lot, offered at €7,000 went for four times that price—€30,000. Other lots did nearly as well.
