Messaggeria in lingua italianaCuprian Elbaite aggiungere nota alla pagina

3rd Mar 2016 11:16 UTCFerdinando Giovine

Su Rivista Gemmologica Italiana 1/2006 pag.65 c'è un articolo di Abduriyim A., Kitawaki H., Furuya M., Schwarz D.: Nomenclatura delle tormaline "Paraiba" (da Gems & Gemology - spring 2006) nel quale si afferma giustamente che il colore di questa tormalina va dal blu elettrico al verde elettrico.

E' proprio questa sua caratteristica, oltre la rarità, che la rende impareggiabile e la più costosa tra le tormaline.

Di questa caratteristica del colore non c'è traccia sulla pagina di Cuprian Elbaite http://www.mindat.org/min-10295.html e nemmeno su http://www.gemdat.org/gem-10295.html

Io penso che andrebbe aggiunta, ma non ho il livello giusto per poterlo fare

http://www.mindat.org/min-10295.html says:

"This material, when used as a gemstone, has been assigned a new formal commercial trade name by the Laboratory Manual Harmonization Committee (LMHC), a group of 7 gemmological laboratories worldwide - Paraíba Tourmaline, regardless of locality of occurrence."

Were you looking for the following page?

http://www.mindat.org/min-29238.html

It was defined as a synonym - have changed it now to a variety, so it will be easier to find.
