Smith et al (2010) studied 20 diamonds (1-2 mm) from Capiibary where 10 of them were studied by CL, and their content in N. Four of them presented inclusions of olivines (Fo 93-94 as harzburgite in Archon lithosphere) and "olivine" with moderate Fo. (92).  As "olivine" with moderate Fo. found in super deep diamonds of Juina/other places Capiibary-"olivine" also present high content in Ca, Na and considerable of Mn and Cr -from Juina "olivines" Kaminsky et al, 2001 "interpreted" as inverted from spinel-structure (Mg,Fe)2Si2O4)).  The Capiibary-"olivine" was analyzed in the largest of the crystals (resorbed aggregate octahedron) -photo; the only diamond that was found to be Type II, where the CL exam shows a center with apparent parallel lines due to plastic deformation.
