Interesting minerals of charoite rocks. Sticite-Stacy

Sticite is a mineral that occurs in charoitites as an accessory impurity, but is the reason for their rejection by the level of radioactive radiation due to the presence of thorium in its composition as one of the mineral-forming elements (K0.3 (Na, Ca) 2ThSi8O20). But, despite its radioactivity, this mineral is used not only as a mineralogical collection material, but also in the form of collectible jewelry cuts. Sticite has a light yellow color and bright green luminescence in ultraviolet rays. The mineral was discovered in 1982 in samples from the igneous massif (Mont Saint-Hilaire) collected at the Poudrette mine in Quebec, Canada. Authors of the discovery: Guy Perrault (1927-2002) , a Canadian mineralogist from Ecole Polytechnique Université de Montréal, University of Montreal, and Jan Tomasz Szymański (born 1938), Canadian mineralogist and crystallographer from the Mineralogical Science Laboratory at the Department of Energy, Mines and Resources of Canada (Mineral Sciences Laboratories, CANMET) in Ottawa. The mineral was named after Harold Robert Steacy (1923-2012), a staff member of the Mineral Sciences Laboratories (CANMET) in Ottawa and deputy curator of the national mineralogical collection of the Geological Survey of Canada. Harold Stacy was one of the initiators of the study of the mineralogy of the rocks of the moon. Also in the world of mineral lovers, Harold Stacy was known as a lover of "magic" jokes and practical jokes, acting as an illusionist.

В геммологической практике бывают весьма увлекательные случаи с диагностикой ювелирных вставок

Но помимо редкости цвета и высокой стоимости таких камней, многие розовые камни выделяются одной замечательной особенностью – они проявляют плеохроизм, то есть в зависимости от положения осмотра камня он может иметь дополнительные оттенки – оранжевый или пурпурный.

Currently, gemstones are produced by two fundamentally different technological methods - the High Pressure - High Temperature method (“HPHT”, High-pressure & High-temperature) and the Chemical Vapor Deposition (“CVD”, Chemical vapor deposition) method. The "HPHT" method is the most tested classical synthesis method, which can be used both carbon deposition on diamond from flux melts and catalytic reactions. In "CVD" synthesis, diamond growth occurs on a seed during carbon deposition mainly from a gaseous medium at relatively low temperatures and pressures.

Jewelry and precious stones are just such a category of goods, when buying which you need to pay attention to many criteria.

Sogdianite is a rather rare mineral and more often it can be found as a collection material (moreover, in systematic collections), and it is extremely rare in jewelry.
