Answer 1

In the Guiness world records book the largerst registered tourmaline is 51.77 cts, found in June 2009, othervise tuormaline inside the smoky qurtz iz measured for about 11 kilos. I've found the in 2005 apiece oif riverstone from river Drava near Maribor , Slovenia , EU a pice of tourmaline with 7315 cts ( as Slovnia is well knowna home laned od dravite-tourmaline /tschermak, 1883, dobova near Dravograd/drauburg ) , without the X-rays spectrography, this one piece could be ferrodravite, chroma dravite or exceptionally schroll.verdelite ( as the mountain of Pohorje is near this place- with the pegamatite and granite geol.ogic environment ). Be so or not to be so- I don't allow any cut-off for spectrography to reduce the weight of that stone ). I've named this stone Marica's Tourmaline ( or MARIZITE (') due the 110th anniversary of Slovene soubrete soprano Marica Brumen Lubejeva, the first poerformer of Floramye by Ivo Tijardtovich,in 1926 -otherwise due my late autnt Marica Kuss ne Cernej, died and residing before at 1094 Bromley Avenue , 0766 Teaneck , New Yersey, who was my donator- for master degree finishing in 1998 at Faculty of Econnomics ;University of Ljubljana): best greatings to Mme Dorothy and Kathleen MIchelle Kuss ( Mote Marine Laboratorise, Sarasota, FL ) and prof. Anthony Milton Jenkins ( University of Baltimore, John Merrick Business Scool - I was his student here in Ljubljna's University ). Basis data are _ 7315 cts, density 3.1 g/cm3, hardness at least 7 , ferromagnetic , piezzomagnetic and pyromagnetic effects are present ( the last one up to 3 h and 17 minutes of duration ).
