Titanite with Ilmenite

Initially I thought it was hematite, but the material was analyzed by Ricardo Scholz in Minas Gerais and the result was Ilmenite.
Few samples purchased from this mining with this cluster have good crystals of Titanite or Ilmenite, most have a lot of condensed ilmenite with small crystals of Titanite, with about 60 samples purchased, only 7 are good enough for more advanced collections.
