Since that time, elbaite been found in many parts of the world. In 1994, a major locality was discovered in Canada, at O’Grady Lakes in the Yukon. Within the metaphysical realm of minerals, elbaite, along with all other minerals in the tourmaline group, dispel fear and negativity, calms the …

Alkali-free tourmaline in the system MgO-Al2O3-B2O3-SiO2

An end member of the tourmaline series with a structural formula (Mg 2 Al)Al 6 (BO 3) 3 [Si 6 O 18](OH) 4 has been synthesized in the system MgO-Al 2 O 3-B 2 O 3-SiO 2-H 2 O where it represents the only phase with a tourmaline structure.
