Updated 2012 American Federation of Mineralogical Societies AFMS Approved Reference List of Lapidary Material Names “Gem List” August 1996 Updated January 2003 AFMS Pubications Committee B. Jay Bowman, Chair Internet version of Approved Lapidary Material Names. This document can only be downloaded at http://www.amfed.org/rules APPROVED NAMES FOR LAPIDARY LABELS Prepared by the American Federation Nomenclature Committee and approved by the American Federa- tion Uniform Rules Committee, this list is the authorized guide and authority for Lapidary Label Names for exhibitors and judges in all competition under AFMS Uniform Rules. All materials are listed alpha- betically with two columns on a page. The following criteria are to assist in the selection and judging of material names on exhibit labels. 1. The name of any listed material (except tigereye), which has been cut to show a single chatoyant ray, may be preceded by “CAT’S-EYE”; the name of any material which has been cut to show asterism (two or more crossed rays) may be preceded by “STAR”, i.e.: CATS-EYE DIOPSIDE, CAT’S-EYE QUARTZ, STAR BERYL, STAR GARNET, etc. 2. This list is not all-inclusive as to the names of Lapidary materials which may at some time be exhibited. If a mineral or rock not included in this list is exhibited, the recognized mineralogical or petrological name must be used. The names of valid minerals and valid mineral varieties listed in the latest edition of the Glossary of Mineral Species by Michael Fleisher, or any other authorized reference, will be acceptable as Lapidary names. Varieties need only have variety name listed and not the root species. Names in this list that are indented belong to the generic name that precedes them. Either name may be used, but not both. Consult the Uniform Rules for the approved references. Refer to the Uniform Rules for additional information required to complete the label and note the following items (3) and (4). 3. Guide to capitalization. Gem names when used in labels, titles or headings, are written in all capital letters, but when used within text material, they are not capitalized. 4. Descriptive terms may be placed on the label, in parentheses if so desired, and will be judged for accuracy, spelling and punctuation, i.e. AGATE, (Crazy Lace) or AGATE Lace; AGATE, (Botswana) or AGATE, Botswana; JASPER (Biggs) or TOURMALINE (Bi-Color), or TOURMALINE, Bi-Color, etc. Guide to stones with inclusions (i.e. EPIDOTED QUARTZ) not found in list, see item (5). 5. If a material is cut and polished as a gem stone, then the name of the base material and the inclusions shall be given, i.e., EPIDOTE in QUARTZ, GOLD in QUARTZ, COPPER in CALCITE, COPPER in DATOLITE, MARCASITE in AGATE, GOETHITE in AGATE, GOETHITE in QUARTZ, etc. Guide to synthetic and artificial stones: See items (6) and (7). 6. Any artificial (no natural counterpart) material not listed below must be preceded by MAN-MADE, i.e., MAN-MADE GLASS 7. Any synthetic (having a natural counterpart) material not listed below must be preceded by SYNTHETIC, i.e., SYNTHETIC RUBY. Internet version of Approved Lapidary Material Names.

  • Age and Origin of Silicocarbonate Pegmatites of the Adirondack Region
    minerals Article Age and Origin of Silicocarbonate Pegmatites of the Adirondack Region Jeffrey Chiarenzelli 1,*, Marian Lupulescu 2, George Robinson 1, David Bailey 3 and Jared Singer 4 1 Department of Geology, St. Lawrence University, Canton, NY 13617, USA 2 New York State Museum, Research and Collections, Albany, NY 12230, USA 3 Geosciences Department, Hamilton College, Clinton, NY 13323, USA 4 Earth and Environmental Sciences, Rensselaer Polytechnic Institute, Rensselaer, NY 12180, USA * Correspondence: [email protected]; Tel.: +1-315-229-5202 Received: 24 July 2019; Accepted: 19 August 2019; Published: 23 August 2019 Abstract: Silicocarbonate pegmatites from the southern Grenville Province have provided exceptionally large crystal specimens for more than a century. Their mineral parageneses include euhedral calc–silicate minerals such as amphibole, clinopyroxene, and scapolite within a calcite matrix. Crystals can reach a meter or more in long dimension. Minor and locally abundant phases reflect local bedrock compositions and include albite, apatite, perthitic microcline, phlogopite, zircon, tourmaline, titanite, danburite, uraninite, sulfides, and many other minerals. Across the Adirondack Region, individual exposures are of limited aerial extent (<10,000 m2), crosscut metasedimentary rocks, especially calc–silicate gneisses and marbles, are undeformed and are spatially and temporally associated with granitic pegmatites. Zircon U–Pb results include both Shawinigan (circa 1165 Ma) and Ottawan (circa 1050 Ma) intrusion ages, separated by the Carthage-Colton shear zone. Those of Shawinigan age (Lowlands) correspond with the timing of voluminous A-type granitic magmatism, whereas Ottawan ages (Highlands) are temporally related to orogenic collapse, voluminous leucogranite and granitic pegmatite intrusion, iron and garnet ore development, and pervasive localized hydrothermal alteration.

  • The Wittelsbach-Graff and Hope Diamonds: Not Cut from the Same Rough
    THE WITTELSBACH-GRAFF AND HOPE DIAMONDS: NOT CUT FROM THE SAME ROUGH Eloïse Gaillou, Wuyi Wang, Jeffrey E. Post, John M. King, James E. Butler, Alan T. Collins, and Thomas M. Moses Two historic blue diamonds, the Hope and the Wittelsbach-Graff, appeared together for the first time at the Smithsonian Institution in 2010. Both diamonds were apparently purchased in India in the 17th century and later belonged to European royalty. In addition to the parallels in their histo- ries, their comparable color and bright, long-lasting orange-red phosphorescence have led to speculation that these two diamonds might have come from the same piece of rough. Although the diamonds are similar spectroscopically, their dislocation patterns observed with the DiamondView differ in scale and texture, and they do not show the same internal strain features. The results indicate that the two diamonds did not originate from the same crystal, though they likely experienced similar geologic histories. he earliest records of the famous Hope and Adornment (Toison d’Or de la Parure de Couleur) in Wittelsbach-Graff diamonds (figure 1) show 1749, but was stolen in 1792 during the French T them in the possession of prominent Revolution.

  • Economic Dimensions of Precious Metals, Stones, and Feathers: the Aztec State Society
    ECONOMIC DIMENSIONS OF PRECIOUS METALS, STONES, AND FEATHERS: THE AZTEC STATE SOCIETY FRANCES F. BERDAN In the spring of 1519, Hernán Cortés and his band of Spanish conquistadores feasted their eyes on the wealth of an empire. While resting on the coast of Veracruz, before venturing inland, Cortés was presented with lavish gifts from the famed Aztec emperor Mocte· zuma IV- While only suggestive of the vastness of imperial wealth, these presents included objects of exquisite workmanship fashioned of prized materials: gold, silver, feathers, jadeite, turquoise.2 There was an enormous wheel of gold, and a smaller one of silver, one said to represent the sun, the other the moon. There were two impressive collars (necklaces) of gold and stone mosaic work: they combined red stones, green stones, and gold bells. s There were fans and other elabo­ 1 Saville (1920: 20-39, 191-206) provides a detailed summary of the many accounts of the gifts presented to Cortés on this occasion. 2 Up to this point in their adventure, sorne of the conquistadores apparently had been sorely disappointed in the mainland's wealth. Bernal Diaz del Castillo repeatedly refers to the gold encountered by the Hernández de Córdova and Gri­ jalva expeditions (1517 and 1518, respectively) as "Iow grade" or "inferior", and small in quantity (Díaz del Castillo, 1956: 8, 22,23, 25, 28). While Díaz, writing many years after the events he describes, seems especially critical of the quality of the gold avaiJable on the coast, the friar Juan Díaz's account of the Grijalva ex­ pedition betrays no such dísappointment.

  • The Hydrous Component in Andradite Garnet
    American Mineralogist, Volume 83, pages 835±840, 1998 The hydrous component in andradite garnet GEORG AMTHAUER* AND GEORGE R. ROSSMAN² Division of Geological and Planetary Sciences, California Institute of Technology, Pasadena, California 91125, U.S.A. ABSTRACT Twenty-two andradite samples from a variety of geological environments and two syn- thetic hydroandradite samples were studied by Fourier transform IR spectroscopy. Their 2 spectra show that H enters andradite in the form of OH . Amounts up to 6 wt% H2O occur in these samples; those from low-temperature formations contain the most OH2. Some 42 ↔ 42 features in the absorption spectra indicate the hydrogarnet substitution (SiO4) (O4H4) whereas others indicate additional types of OH2 incorporation. The complexity of the spectra due to multi-site distribution of OH2 increases with increasing complexity of the garnet composition. 42 ↔ 42 INTRODUCTION tution (O4H4) (SiO4) .

  • Christie's Presents Jewels: the Hong Kong Sale
    FOR IMMEDIATE RELEASE October 28, 2008 Contact: Kate Swan Malin +852 2978 9966 [email protected] CHRISTIE’S PRESENTS JEWELS: THE HONG KONG SALE Jewels: The Hong Kong Sale Tuesday, December 2 Christie’s Hong Kong Hong Kong – Christie’s announces the fall sale of magnificent jewellery, Jewels: The Hong Kong Sale, which will take place on December 2 at the Hong Kong Convention and Exhibition Centre. This sale features an exquisite selection of over 300 extraordinary jewels across a spectrum of taste and style, from masterpieces of the Belle Époque to contemporary creations, and from the rarest of white and coloured diamonds to important coloured stones. COLOURLESS DIAMONDS Leading the auction is a rare pair of D colour, Flawless diamonds weighing 16.11 and 16.08 carats (illustrated right, estimate: HK$40,000,000-60,000,000 / US$5,000,000-8,000,000). These marvellous stones are also graded ‘Excellent’ for polish, symmetry and cut grade, making them exceedingly rare for their superb quality. Classified as Type IIa, these diamonds are the most the chemically pure type of diamonds known, with no traces of the colorant nitrogen. The absence of this element, seen in 98% of diamonds, gives these stones a purity of colour and degree of transparency that is observed only in the finest white diamonds. The modern round brilliant cut is the diamond’s most basic and popular shape, as it allows the potential for the highest degree of light return. But more importantly, the round diamond sustains the highest value as its production requires riddance of the greatest amount of diamond rough.

  • The New IMA List of Gem Materials – a Work in Progress – Updated: July 2018
    The New IMA List of Gem Materials – A Work in Progress – Updated: July 2018 In the following pages of this document a comprehensive list of gem materials is presented. The list is distributed (for terms and conditions see below) via the web site of the Commission on Gem Materials of the International Mineralogical Association. The list will be updated on a regular basis. Mineral names and formulae are from the IMA List of Minerals: http://nrmima.nrm.se//IMA_Master_List_%282016-07%29.pdf. Where there is a discrepancy the IMA List of Minerals will take precedence. Explanation of column headings: IMA status: A = approved (it applies to minerals approved after the establishment of the IMA in 1958); G = grandfathered (it applies to minerals discovered before the birth of IMA, and generally considered as valid species); Rd = redefined (it applies to existing minerals which were redefined during the IMA era); Rn = renamed (it applies to existing minerals which were renamed during the IMA era); Q = questionable (it applies to poorly characterized minerals, whose validity could be doubtful). Gem material name: minerals are normal text; non-minerals are bold; rocks are all caps; organics and glasses are italicized. Caveat (IMPORTANT): inevitably there will be mistakes in a list of this type. We will be grateful to all those who will point out errors of any kind, including typos. Please email your corrections to [email protected]. Acknowledgments: The following persons, listed in alphabetic order, gave their contribution to the building and the update of the IMA List of Minerals: Vladimir Bermanec, Emmanuel Fritsch, Lee A.

  • Thank You, Shaun Shelton, for a Very Informative Program on Cleaning Specimens with an Impressive Array of Minerals Displayed
    Volume 57 Number 8 August 1, 2016 From Da Prez: Thank you, Shaun Shelton, for a very informative program on cleaning specimens with an impressive array of minerals displayed. We learned a lot, even who is ready with a short joke once asked! A large group of 11 travelled to Marshall, NC for the month’s field trip to Little Pine Garnet Mine. I believe it was about 6 degrees cooler there at 90 degrees, and even cooler inside the mine, of course. The mine has changed and weathered considerably in the last few years. Digging in the creek bank proved to be the most productive as Steve Smith and Mike Smagner found. At least they gave us a group discount rate. Unless more of the mine is opened up, I don’t know that it will be cost effective as a destination, but always good to get outdoors and find a few specimens. We hope many of you can make it for the Grassy Creek Show and to Crabtree Mine while in the area of Little Switzerland and Spruce Pine. [ The] August meeting will offer a rare look into the history of the club, offered by Joe Maguire [Gary Parker, Ed Deckert, Joyce Patton, Steve Smith, John Hiller, Mary Pendergraph, and others.] See you soon!
