ELDARITE - GEMSTONE DICTIONARY Eldarite. Trade names for a type of rhyolite, a volcanic rock mainly consisting of quartz, feldspar, pyroxene (aegirine) and hornblende (amphibole). The material is often misnamed Jasper. Some dealers say it is a form of stromatolite of fossilized algae. Both of these theories have been proven wrong.

Spessartine Garnet. Orange to dark brownish-red garnet. Forms a series with Almandine and Pyrope (Pyralspite Series) Contrary to pyrope or almandine, spessartine is quite rare. As a species of its own spessartine has only been recognized at the end of the 19th century. In early gemmological literature spessartine is not mentioned, partly BOWENITE - GEMSTONE DICTIONARY Bowenite. A variety of the mineral antigorite, which belongs to the serpentine group. The serpentine group encompasses 20 minerals and their varieties. Best known is the fibrous chrysotile asbestos, which was used as a building material until the 1990ies before it was found to be carcinogenic.

The mine is located near the mining town of Newman, about 700 miles north east of Perth, the capital of Western Australia. Noreena jasper is silicified pelite (mudstone). The composition of jasper varies greatly. AQUAMARINE - GEMSTONE DICTIONARY Aquamarine is one of very few gems, whose price per carat may decrease as its size increases.

Gemstones in which the colouring elements are constituent parts of the chemical formula.

When white light passes through a coloured gem, certain colours will be absorbed more than others. The colours least absorbed combine to produce the colour of the gemstone. When viewed through a spectroscope, the absorbed wavelengths produce dark or black absorption bands at certain positions in the spectrum.GLASS-FILLED RUBY
Glass-filled Ruby AGL (American Gemological Laboratories) und GRS (GemResearch Swisslab) agree on nomenclature for glassfilled rubies. Background In 2003 the first glass-filled rubies appeared on the international gem markets. The raw material for these stones is low-grade ruby (so low-grade that the term "corundum" is actually more applicable) from East Africa. BOWENITE - GEMSTONE DICTIONARY - EDELSTEINE Bowenite. A variety of the mineral antigorite, which belongs to the serpentine group. The serpentine group encompasses 20 minerals and their varieties. Best known is the fibrous chrysotile asbestos, which was used as a building material until the 1990ies before it was found to be carcinogenic.

PERIDOT - GEMSTONE DICTIONARY - EDELSTEINE Peridot. Peridot is the name for the gem quality members of the olivine group, a group of miscible silicates with isomorphous replacement. The endmembers of the olivine group are an iron silicate called fayalite and tephroit, a manganese silicate. Other members are forsterite, glaucochroite, kirschsteinite, laihunite, monticellite andthe
GARNET - GEMSTONE DICTIONARY garnet is a complex group of miscible silicates with isomorphous replacement. Isomorphous means, that some elements in the chemical formula can be replaced by others without changes in the crystal structure. Thus the chemical composition of garnet varies withincertain limits.
TURQUOISE - GEMSTONE DICTIONARY - EDELSTEINE Turquoise. A hydrous copper-aluminium-phosphate. By isomorphous replacement iron (Fe 3+) can substitute for the aluminium, so the composition varies to some extent Turquoise shop Antique Persian Turquoise with matrix and Pyrite inclusions Origin of name: from the french word turquoise for "turkish", because Persian and probably also Egyptian (Sinai Peninsula) entered Europe by way of TurkeyVIENNA GEM CENTER
