Imagine going into the diamond bourse and you see thousands of carats being sold with one expression as the only guarantee: “Mazal”. With this, the deal is concluded. No written proof or contract is needed. “Mazal” is the insurance for an agreed price. In such a way each year thousands of stones change hands in all confidence. This is the Jewish tradition, as Mazal means good luck. Another tradition is the offering of a diamond to celebrate a happy event such as birth, engage- ment, and marriage. A beautiful tradition, also for the diamond trade. It has stimulated the market for centuries and has made it become as powerful as it is nowadays. Behind that market is a profession © H.A.

All materials are listed alpha- betically with two columns on a page. The following criteria are to assist in the selection and judging of material names on exhibit labels. 1. The name of any listed material (except tigereye), which has been cut to show a single chatoyant ray, may be preceded by “CAT’S-EYE”; the name of any material which has been cut to show asterism (two or more crossed rays) may be preceded by “STAR”, i.e.: CATS-EYE DIOPSIDE, CAT’S-EYE QUARTZ, STAR BERYL, STAR GARNET, etc. 2. This list is not all-inclusive as to the names of Lapidary materials which may at some time be exhibited. If a mineral or rock not included in this list is exhibited, the recognized mineralogical or petrological name must be used. The names of valid minerals and valid mineral varieties listed in the latest edition of the Glossary of Mineral Species by Michael Fleisher, or any other authorized reference, will be acceptable as Lapidary names. Varieties need only have variety name listed and not the root species.

    SES 201 6 Twelfth Scientific Conference with International Participation SPACE, ECOLOGY, SAFETY 2– 4 November 2016, Sofia, Bulgaria USE OF MINERALS IN THE ENVIRONMENT AND THEIR ROLE IN HEALTHCARE Mirjana Despotovic Jovanovska, Jane Velkoski GAPE Institute – Skopje, Republic of Macedonia e-mail: [email protected] Key words: mineralogy, crystals, human energy Abstract: Mineralogy is one of the basic branches of Geology, which studies the minerals, their chemical composition, crystal structure and physical properties.Some mineralogy disciplines include processes of appearance and formation of minerals, their classification, geographic spread, as well as the possibility of their use. Scientists dealing with mineralogy are called mineralogists. The minerals and crystals are everywhere around us and they have a wide range of use – in the creation of art works and decorative objects, in cosmetics, in official medicine, in modern technology, industry etc. All these uses include the application of crystals and minerals in treatment of people and the environment. Introduction A mineral is a chemical element or a compound which is normally crystallized and was created by the influence of geological processes; it has a certain chemical compositions, which does not have to be constant and a defined crystal condition which does not have to be crystallized.
