  • 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.

  • Preliminary Investigation of Purple Garnet from a New Deposit in Mozambique
    GIT GEMSTONE UPDATE Preliminary Investigation of Purple Garnet from a New Deposit in Mozambique By GIT-Gem testing laboratory 11 May 2016 Introduction In March 2016, a group of Thai gem dealer led by Mr. Pichit Nilprapaporn paid a visit to the GIT and informed us about a new garnet deposit in Mozambique, that was discovered near the western border with Zimbabwe. They also displayed a large parcel of rough and a few cut stones claimed to be the material found in this new deposit (Figure 1). According to the stone’s owner, these garnet specimens were unearthed from an unconsolidated sediment layer, just a few meters below ground surface. This brief report is our preliminary investigation on the interesting vivid purple garnet from the new deposit in Mozambique.

Shapiro Feb. 7, 2018 4:12 p.m. ET The fancy color diamond market is on the upswing, according to a report, with blue diamonds seeing the largest gains. Blue diamonds saw a 5.9% increase in value in the fourth quarter of 2017 in a year-over-year comparison, according to data published on Feb. 1 by the Fancy Color Research Foundation (FCRF). Pink and yellow diamond prices decreased slightly in the same period, at 0.8% and 1.8%, respectively. The market overall was up 0.1%. A fancy vivid blue diamond ring (est. $14-18 million) goes on view at Sotheby's on Oct. 13, 2017 in London. ILLUSTRATION: GETTY IMAGES FOR SOTHEBY'S In November 2017, Christie’s sold a 8.67-carat fancy intense blue diamond ring in Geneva, Switzerland for $13.2 million. The reason for this disparity has less to do with demand, than it does with the rarity of the stone, says FCRF Chairman Eden Rachminov. Demand for yellow and pink diamonds is actually higher, but the amount of blue diamonds being mined is decreasing. “Almost nothing is coming out of the ground,” he says. Pink diamonds have seen the highest gains in the last 13 years with an overall appreciation of 361.9%, according to FCRF’s index, which is compiled through survey data provided by manufacturers and brokers.

  • Get Reactive in System 96!
    Get Reactive in System 96! Uroboros has created two unique glass formulas for System 96 that are designed to create an interface color, or a reac on, when melted against certain other colors. This occurs when ions from the two adjacent glasses migrate and mingle when the gl asses become hot and ß uid. Given the right glass chemistry, the comingled ions form a very thin colored line, or reac on. Since our formulas react to create a no ceably reddish hue we named them Red Reac ves: as in Red Reac ve Transparent, and Red Reac ve Opal. The primary ingredient needed in a glass to generate a reac on color with our Reac ve glass is Copper. Copper is present in many blue and blue-green glass colors, but in some cases in too low a concentra on to create a no ceable reac on. For simplicity, all System 96 colors have been graded for their poten al to react into three categories: Strong, Medium, and Mild. See them all listed in the chart on the back of this page. You will Þ nd that the intensity of the reac on color will get stronger with longer, ho er, or repeat Þ rings. This is because the copper ions have more me to mingle with their friendly reac ve partners in the adjacent glass. The chart rankings are based on a typical single Þ ring cycle. You could get a Medium reac on from a color graded as Mild by Þ ring it ho er, or Þ ring mul ple mes.

    Piece Mold, Lost Wax & Composite Casting Techniques of the Chinese Bronze Age Behzad Bavarian and Lisa Reiner Dept. of MSEM College of Engineering and Computer Science September 2006 Table of Contents Abstract Approximate timeline 1 Introduction 2 Bronze Transition from Clay 4 Elemental Analysis of Bronze Alloys 4 Melting Temperature 7 Casting Methods 8 Casting Molds 14 Casting Flaws 21 Lost Wax Method 25 Sanxingdui 28 Environmental Effects on Surface Appearance 32 Conclusion 35 References 36 China can claim a history rich in over 5,000 years of artistic, philosophical and political advancement. As well, it is birthplace to one of the world's oldest and most complex civilizations. By 1100 BC, a high level of artistic and technical skill in bronze casting had been achieved by the Chinese. Bronze artifacts initially were copies of clay objects, but soon evolved into shapes invoking bronze material characteristics. Essentially, the bronze alloys represented in the copper-tin-lead ternary diagram are not easily hot or cold worked and are difficult to shape by hammering, the most common techniques used by the ancient Europeans and Middle Easterners. This did not deter the Chinese, however, for they had demonstrated technical proficiency with hard, thin walled ceramics by the end of the Neolithic period and were able to use these skills to develop a most unusual casting method called the piece mold process. Advances in ceramic technology played an influential role in the progress of Chinese bronze casting where the piece mold process was more of a technological extension than a distinct innovation. Certainly, the long and specialized experience in handling clay was required to form the delicate inscriptions, to properly fit the molds together and to prevent them from cracking during the pour.

The features of the five peaks due to phonon sidebands of the main peak. emission and excitation spectra of the orange-yellow flu- – orescence of these sodalites are independent of the locality. Keywords Sodalite Á Photoluminescence Á S2 center Á The emission spectra at 300 and 10 K consist of a broad Heat treatment Á Fine structure band with a series of peaks and a maximum peak at 648 and 645.9 nm, respectively. The excitation spectra ob- tained by monitoring the orange-yellow fluorescence at 300 Introduction and 10 K consist of a main band with a peak at 392 nm. The luminescence efficiency of the heat-treated sodalite Natural sodalite represented by the ideal formula Na8Al6 from Xinjiang is about seven times as high as that of un- Si6O24Cl2 or 3(Na2OÁAl2O3Á2SiO2)Á2NaCl is a well-known – treated natural sodalite. The emission spectrum of the S2 fluorescent mineral emitting orange-yellow fluorescence center in sodalite at 10 K consists of a band with a clearly under ultraviolet (UV) light.
