Abstract:

AbstractAn overview is presented of gemstones from eastern Kazakhstan in terms of their geographical distribution, geological provenance and genesis, gemmological characteristics, historical use and current applications. Locally occurring precious, semi-precious and decorative stones were extracted and traded along the northern part of the Silk Road that traversed the area in earlier historical times. Currently, non-metallic minerals, which largely originate from mafic igneous and metamorphic bodies of the Altay and Kalba Mountains of Kazakhstan, still are insufficiently known and exploited in

Abstract:

Abstract The essay explores the role of gemstone merchants, jewelers and goldsmiths in the expropriation of diamonds, jewellery and precious stones from the Jewish population of Germany as well as German-occupied countries in the Nazi era. Their participation along with the possibility for them to profit from these efforts will be highlighted, and it will be shown in how far there is proof for the involvement of specific persons. Due to their changeable nature, many of the stolen pieces of jewellery are nigh impossible to trace. For this reason, the essay narrows its focus on individual gemsto

Abstract:

This paper will explore the perceived connection between gemstones and celestial potencies in particular magical currents in the cultures of the West, and the ritual use of gemstone talismans, amulets, and jewellery to invoke, persuade, learn from, or merge with celestial potencies. Underpinning this magical use of precious and semiprecious stones is the idea of correspondences or sympathies between the divine and the mortal realms, most emphasised through the significance of colour – itself understood, in certain currents of thought, to reflect the importance of sight as the organ of percepti

Abstract:

Gilgit-Baltistan has tremendous amount of gemstone wealth and thousands of miners are busy to explore this wealth, but due to unscientific and crude mining methods this mineral wealth goes into waste in many ways, like fractures, damages and total destructions of gemstone due to ill blasting methods and lack of proper training. Gemstone mining is done in all districts of Gilgit-Baltistan. According to a careful survey in July 2007, 32 types of Gemstones (Precious and Semiprecious) are found in GB, out of total production of gemstones produced in Pakistan 95% come from GB.

Abstract:

This paper describes a method for detecting defects inside high-refractive index gems. This method consists in immersion of a precious stone inside low-melting chalcogenide glass. After cooling, molten glass turns into a solid phase and is an optical cube. This cube can be photographed in layers and using OctoNus equimpment a 3D model of gemstone defects can be built. The proposed method allows you to effectively and accurately determine the coordinates of the defects in diamond and to offer the most profitable option for polishing a precious stone.

Abstract:

Oltustone is a semi-precious gemstone found only in the Late Cretaceous (Upper Maastrichtian) Dutlu Formation of Turkey. Microscopic examination of oltustone reveals that it consists of fossilized Agathoxylon wood (Araucariaceae). This represents one of the latest occurrences of the Araucariaceae in southern Eurasia and is also the southernmost recorded for the Laurasian continent.
