Ammosov, Institute of Finances and Economics, Sakha (Yakutia), Russia 4 Peter the Great St. Petersburg Polytechnic University, St Petersburg, Russia Abstract. The paper analyzes the condition of electrical grids in the west of the Republic of Sakha (Yakutia); data sampled for the last 10 years. It demonstrates the geographic location of grids, which defines the scale of the study. Technical indicators are presented for 10 years; they reflect an increase in the fixed assets. The paper derives mathematical models of the wear of transmission equipment used in the western grids. It proves that the condition of equipment will deteriorate further unless its maintenance is properly funded. The paper analyzes the prospects of electrical grids in the Republic of Sakha (Yakutia). It presents a program for local energy optimization. The costs associated with five alternative development scenarios are calculated and presented in a tabular format. 1 Introduction 30% of the total heat in the Republic. HPPs account for 37.5% of the installed capacity. -

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.

HIGHLIGHTS and BREAKTHROUGHS Sapphire, A
1 HIGHLIGHTS AND BREAKTHROUGHS 2 Sapphire, a not so simple gemstone 3 F. LIN SUTHERLAND1* 4 1Geoscience, Australian Museum, 1 William Street, Sydney, NSW 2010, Australia. 5 *E-mail: [email protected] 6 Abstract: Sapphire is a gemstone of considerable reach and is much researched. It still delivers scientific surprises, as exemplified by a 7 recent paper in American Mineralogist that re-interprets the origin of needle-like rutile inclusions that form “silk” in sapphires. 8 Understanding of variations in sapphire genesis continues to expand. Keywords: Sapphire, inclusions, trace elements, genesis 9 Sapphire as a gem variety of corundum has wide use in the gem trade as one of the more historically valuable colored gem stones 10 (CGS) and is mined from a great variety of continental gem deposits across the world. A masterly compendium on this gemstone and its 11 ramifications is recently available (Hughes 2017). As a gem, sapphire ranges through all the colors of corundum, except where 12 sufficient Cr enters its α-alumina crystal structure and causes the red color of the variety ruby. Sapphire, as a key pillar in a wide 13 economic network of gem enhancing treatments, jewelry and other manufacturing enterprises, has elicited numerous scientific and 14 gemological enquiries into its internal nature and natural genesis and subsequent treatments. A further use of sapphire as a synthetic 15 material with a great variety of purposes also has triggered a proliferation of detailed studies on its growth, properties and other element 16 substitutional effects (Dobrovinski et al. 2009). Even with this vast range of studies, this apparently simple gemstone still yields 17 controversies and breakthroughs in understanding its genetic formation. -

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. -
