Magnetic Susceptibility Index for Gemstones ©2010 Kirk Feral Magnetic Responses Are Standardized to 1/2" X 1/2" N-52 Magnet Cylinders
Magnetic Susceptibility Index for Gemstones ©2010 Kirk Feral Magnetic responses are standardized to 1/2" X 1/2" N-52 magnet cylinders. Colorless and extremely pale stones of any species tend to be Inert (diamagnetic). Black opaque stones of many species are strongly magnetic and may Pick Up or Drag. Pick Up and Drag responses are weight-dependent. Direct responses on the Index apply to gems 1-4cts. Larger gems may be too heavy to Pick Up or Drag. Smaller non-Garnet gems with strong magnetism may Pick Up.

An Exploration of Jade Abstract Abstract: This is a research paper studying the history of Jade carving during the Chinese Han Dynasty from 206 B.C to 220 A.D. The ap per explains the meaning of jade to the Chinese people and examines the origin of the precious stone for the Han people and other generations of dynasties. There is an accurate telling of Han beliefs followed by a descriptive passage on the history of religious influence on the Han people. There is an extensive study on the history of the Han people in general and a lengthy report on the different forms of jade and their functions for the Han people.

Mineralogy and Geochemistry of Nephrite Jade from Yinggelike Deposit, Altyn Tagh (Xinjiang, NW China)
minerals Article Mineralogy and Geochemistry of Nephrite Jade from Yinggelike Deposit, Altyn Tagh (Xinjiang, NW China) Ying Jiang 1, Guanghai Shi 1,* , Liguo Xu 2 and Xinling Li 3 1 State Key Laboratory of Geological Processes and Mineral Resources, China University of Geosciences, Beijing 100083, China; [email protected] 2 Geological Museum of China, Beijing 100034, China; [email protected] 3 Xinjiang Uygur Autonomous Region Product Quality Supervision and Inspection Institute, Xinjiang 830004, China; [email protected] * Correspondence: [email protected]; Tel.: +86-010-8232-1836 Received: 6 April 2020; Accepted: 6 May 2020; Published: 8 May 2020 Abstract: The historic Yinggelike nephrite jade deposit in the Altyn Tagh Mountains (Xinjiang, NW China) is renowned for its gem-quality nephrite with its characteristic light-yellow to greenish-yellow hue. Despite the extraordinary gemological quality and commercial significance of the Yinggelike nephrite, little work has been done on this nephrite deposit, due to its geographic remoteness and inaccessibility. This contribution presents the first systematic mineralogical and geochemical studies on the Yinggelike nephrite deposit. Electron probe microanalysis, X-ray fluorescence (XRF) spectrometry, inductively coupled plasma mass spectrometry (ICP-MS) and isotope ratio mass spectrometry were used to measure the mineralogy, bulk-rock chemistry and stable (O and H) isotopes characteristics of samples from Yinggelike. Field investigation shows that the Yinggelike nephrite orebody occurs in the dolomitic marble near the intruding granitoids. Petrographic studies and EMPA data indicate that the nephrite is mainly composed of fine-grained tremolite, with accessory pargasite, diopside, epidote, allanite, prehnite, andesine, titanite, zircon, and calcite. Geochemical studies show that all nephrite samples have low bulk-rock Fe/(Fe + Mg) values (0.02–0.05), as well as low Cr (0.81–34.68 ppm), Co (1.10–2.91 ppm), and Ni (0.52–20.15 ppm) contents. -

The Philippines is a consumer, source, and transit point for IWT, threatening endemic species populations, economic development, and biodiversity. The country has been a party to the Convention on Biological Diversity since 1992. The value of IWT in the Philippines is estimated at ₱50 billion a year (roughly equivalent to $1billion), which includes the market value of wildlife and its resources, their ecological role and value, damage to habitats incurred during poaching, and loss in potential -

Less than 250 adults in the wild, populations highly fragmented and declining; IUCN 2009) (last assessed Range: Philippines in 1996). Taxonomic Status The Philippine crocodile was described in 1935 by Karl Schmidt on the basis of a type specimen and three paratypes from the island of Mindoro (Schmidt 1935, 1938). Schmidt also described the closely related New Guinea freshwater crocodile (Crocodylus novaeguineae) in 1928 and later made a comparison of morphological differences between C. mindorensis, C. novaeguineae and C. porosus, maintaining C. mindorensis as a separate species (1956). However the Philippine crocodile has long been treated as C. novaeguineae mindorensis, a sub-species of the New Guinea crocodile, by other authorities. Hall (1989) provided new evidence of the distinctness of the Philippine crocodile and nowadays C. mindorensis is generally treated as a full species endemic to the Philippines. Figure 1.

In this report, the terms “gem” and “gemstone” mean any gemstones and on the cutting and polishing of large diamond mineral or organic material (such as amber, pearl, petrified wood, stones. Industry employment is estimated to range from 1,000 to and shell) used for personal adornment, display, or object of art ,500 workers (U.S. International Trade Commission, 1997, p. 1). because it possesses beauty, durability, and rarity. Of more than Most natural gemstone producers in the United states 4,000 mineral species, only about 100 possess all these attributes and are small businesses that are widely dispersed and operate are considered to be gemstones. Silicates other than quartz are the independently. the small producers probably have an average largest group of gemstones; oxides and quartz are the second largest of less than three employees, including those who only work (table 1).

Ecotown Scale-Up Project: Climate Resilient Green Growth Planning At
Ecotown Scale-Up Project: Climate Resilient Green Growth Planning at the Provincial Level Assessment of Outcomes, Mainstreaming and Next Steps Ecotown Scale-Up Project: Climate Resilient Green Growth Planning at the Provincial Level: Assessment of Outcomes, Mainstreaming, and Next Steps I. Overview The Ecotown Scale-Up Project, also referred to as the Climate Resilient Green Growth Planning Project (CRGG Project) was implemented by the Global Green Growth Institute (GGGI) and the Climate Change Commission (CCC) in the Provinces of Palawan and Oriental Mindoro from 2016 to 2018 to: a.) Enhance climate change resilience and promote inclusive green growth in participating provinces; and b.) Replicate climate resilient green growth planning and implementation models in other provinces to institutionalize the approach at the national level. The project built-on the lessons of the earlier Demonstration of Ecotown Framework Project implemented at the municipal level and the implementation of the CRGG Project at the provincial level was meant to attain scale in terms of number of LGUs that would be benefited. The Provinces of Oriental Mindoro and Palawan consist of 41 local government units (i.e., 2 Provincial Governments, 2 City Governments, and 37 Municipal Governments) and account for a population of almost 2 million. The two provinces were selected considering their exposure to natural calamities and their strategic importance to the rest of the country. Oriental Mindoro is considered the “Food Basket of the MIMAROPA Region” as it supplies most of the rice, fruits, and high value crops in the region. Agriculture is the main economic driver of the province, supporting 62% of its 840,000 population yet this sector is considered most vulnerable to climate change impacts.
